The present invention is directed to a footwear fitment and more particularly to a footwear fitment that is an upper-foot carried orthotic that improves foot comfort by helping position footwear worn on a foot carrying the fitment and/or helping snug footwear around a foot wearing the fitment.
The human foot is a relatively complicated part of the human body that we use every day when we stand, walk, work, dance, jog, and run using our feet. The foot is elongate and formed of three distinct regions including a hindfoot or rear foot region at the rear of the foot, which includes the heel formed of the calcaneus or heel bone and a posterior part of the ankle that includes the talus or ankle bone, a forefoot or front foot region at the front of the foot, which includes the toes, metatarsal bones and ball of the foot, and a midfoot or middle foot region forming the middle of the foot extending between the hindfoot and forefoot, which includes an arch and instep along the underside of the foot and a bridge along the top of the foot together with tarsal bones that form an anterior part of the ankle or anterior ankle. The foot has a dorsal side extending along the top of the foot that also can be referred to as the dorsum (the surface of the midfoot and forefoot that faces upwardly while standing), a plantar side extending along the sole or bottom of the foot that also can be referred to as the planum (the surface of the foot that faces downwardly while standing), a distal side along the front of the foot where the toes are located, a proximal side along the rear of the foot where the heel is located, a medial side along an inboard side of the foot along where the arch of the foot is located, and a lateral side along an outboard side of the foot. The foot is connected to the bones of the leg, namely the tibia and fibula, by the ankle with the anterior ankle being part of the midfoot region of the foot that extends from the anterior ankle forwardly or distally to the Lisfranc joint where the tarsal and metatarsal bones connect.
Many specialized types of footwear, mostly specialized types of shoes and boots, have been developed over the years that are designed to protect our feet, improve performance for the type of activity for which they are intended to be worn, absorb and reduce foot impact forces transmitted to other parts of the body, encourage proper posture, and increase safety all while typically being aesthetically pleasing. Examples of different types of shoes include dress shoes, such as oxfords and bluchers, heeled shows, such as high heeled boots or high heeled shoes like stilettos and slingbacks, for women, sneakers, loafers, tennis shoes, track shoes, baseball and football cleats, boat shoes, steel-toed shoes, and other types of shoes which substantially enclose each foot of a person wearing them. Examples of different types of boots include hiking boots, military or combat boots, logger boots, cowboy boots, steel-toed boots, high heeled boots, chukkas and Chelsea boots which substantially enclose each foot and typically a lower portion of the leg of a person wearing them.
Shoe and boot footwear are typically designed to substantially enclose or encapsulate the foot of the person wearing them. They are commonly composed of an elongate sole that underlies and supports the corresponding elongate fore-aft or medial-distal extending lengthwise extent of a sole or bottom of a foot and an upper extending upwardly from the sole which forms an enclosure or housing that wraps around the rest of the foot typically covering substantially the entire hindfoot, midfoot and hindfoot regions of the foot. The sole of the shoe or boot typically includes an insole upon which the sole of the foots rests, an outsole contacting the ground or floor during use and which can include a heel at the rear that underlies a heel of the foot, and which can further include a midsole between the insole and outsole. The shoe or boot upper includes a counter along the rear that wraps around and can cup the heel of the foot, side panels or quarters that extend along opposite sides of the foot, a vamp that extends along the dorsum, dorsal, top or upper portion of the foot with the vamp typically including a toe-box or toe-puff enclosing the toes and which also can have an elongate tongue extending between the quarters or side panels outwardly toward an ankle of the foot. Where the footwear is a boot, the tongue of the vamp can also extend upwardly to and along part of the leg.
The relatively complex structure of the foot along with variations in size, shape and structure common amongst the population combined with differences in footwear construction, design, material performance and durability characteristics, wear patterns, stability, support and the like make choosing footwear that not only fits properly when purchased but which retains adequate fit after break-in and during prolonged usage remains an incredibly difficult challenge. While fitting problems are common with people who have narrower Fitting problems are well known with people who have narrower or wider than average feet. However, it is not uncommon for footwear that appears properly fitted at purchase to lose proper fit due to stretching, sole compaction or wear over time for everyone, not just those with narrow or wide feet.
In the past, numerous different types of devices have been tried with mixed success to improve foot comfort, relieve foot and joint pain, provide arthritis relief, help promote injury healing, facilitate injury rehabilitation, prevent overuse, provide orthopedic correction, reduce odor, or improve athletic performance. In almost all instances, these devices are in the form of foot orthotics or foot orthosis that are configured for in-shoe placement, typically in the form of a shoe insert, e.g., shoe orthotic insert, which is inserted into the shoe so it overlies the shoe insole and underlies the foot of a person wearing the shoe in which the insert has been placed.
Unfortunately, choosing from myriad types of available shoe inserts is often a trial and error process that is as challenging as it is confusing such that it is not uncommon for a person to purchase several, sometime several dozen, different types, constructions and shapes of shoe inserts until they find one that helps. While shoe sizes are supposed to be uniform, there often are slight but significant variations in width, length, contour, fit, and the like amongst shoes of a given size sometimes making it very difficult to find a shoe that fits, let alone an insert that fits. Even if the insert fits, these shoe size variations can slightly offset the proper location of the insert in the shoe relative to a foot received in the shoe thereby reducing or even negating the effectiveness of the insert. Even when a shoe insert helps, it often does not completely solve all of the problems that led them to shoe inserts in the first place.
This is especially true of many types of women's shoes, particularly high-heeled boots. Many women report foot, knee, hip, and lower back pain while wearing high heeled boots. Such pain tends to be caused by increased pressure on the toes and ball of the foot due to the foot sliding forward in high-heeled shoes, the increased amount of time the ball of the foot is on the ground during each step, the increased pressure high heeled shoes cause to be put on the medial or big toe side of the foot, the use of a flattened heel pad in high-heeled shoes, the significantly increased strain placed on the Achilles tendon during each step wearing high-heeled shoes which tends to want to shorten Achilles tendon length, the failure to properly extend the knee through its full range of motion, during each step, e.g., lack of terminal knee extension with gait, and the adverse impact high-heeled shoes can have upon lower back curvature, e.g., increased lumbar lordosis, over time. Prior attempts have been made to add cushioning or change the shape of high-heeled shoes to decrease the pain and other such maladies associated with high-heeled shoe use have met with limited success. While there also have been many prior attempts at designing shoe inserts for high-heeled shoes, such designs not only possess limited effectiveness, they are also very difficult to make that fit all types of high-heeled shoes for a given size.
While wearers of boots and other types of shoes have fewer problems than high-heeled shoe wearers, problems nonetheless persist. While many of the myriad shoe insert orthotic devices out on the market do provide some relief, quite often they too do not address all of the problems suffered by the wearer. This is because virtually all of these shoe inserts do nothing to correct fore-aft foot location misalignment that typically occurs with improperly fitting shoes and boots. And virtually all of these shoe inserts do nothing to compensate for problems with shoes and boots that fit poorly because they are too large or have become too large for the foot of the wearer with extended use.
What is needed is an orthotic device that overcomes one or more of the above-shortcomings of existing in-shoe placed orthotics. What is needed is an orthotic device suitable for use with heeled shoe wearers, particularly high-heeled shoe wearers, to alleviate at least some of myriad problems typically experienced by them. What also is needed is an orthotic device that helps properly align the shoe on the foot and/or the foot in the shoe. What is still further needed is an orthotic device that compensates for shoes and boots that have too large of a fit or become too large over time due to stretching, wear and the like as typically occurs the longer the shoe or boot is worn by a user. What also is needed is a device that addresses one or more of the above-shortcomings of in-shoe placed foot orthotics like shoe inserts whose use and operation is not limited by subjective personal preferences and differences in shoe variations for a given shoe size.
The present invention is directed to a foot-carried shoe orthotic in the form of a footwear comfort improving fitment that is carried or worn on a top portion of a foot received in an article of footwear, such as a shoe or boot, disposing the fitment between the top portion of the foot and a top portion of an upper or vamp of the footwear for snugging up the footwear around the foot thereby improving comfort by improving fit of the footwear on the foot. The fitment includes at least a plurality of pairs, i.e., at least three, layers that include a pair of outer layers and at least one inner layer between the outer layers that is a pad that provides a spacer giving thickness or volume to the fitment to provide footwear snugging when worn on top of a foot inserted into the footwear. In a preferred embodiment, the fitment is retained against the skin of the top portion of the foot, preferably a midfoot region adjacent the ankle, by hosiery, such as a sock, worn over the foot before placement into the footwear with the hosiery maintaining proper location of the fitment relative to the top portion of the upper or vamp of the footwear worn by the foot.
In one preferred embodiment, the outer layers of the fitment are constructed of cloth or fabric and the one or more inner layers are composed of two or more layers of wool, cotton, or a synthetic material that can be of woven or nonwoven construction. In a second preferred embodiment, a first outer layer of the fitment covers a first surface of the fitment intended to face and be in contact with skin of the top of the foot of a person wearing the fitment with the first outer layer being composed of a material possessing increased friction that engages with the skin on the top of the foot to prevent the fitment from sliding relative to the foot during footwear snugging use. In the second preferred embodiment, a second outer layer is composed of a lower friction slippery material that is covered by hosiery, e.g., sock, covering the foot thereby preventing the fitment from being moved by the hosiery relative to the foot against which the fitment is disposed. In the second embodiment, the at least one inner layer is composed of a foam layer, such as a foam layer made of a urethane foam, which can be an open cell foam, but which preferably is a closed cell foam.
The fitment preferably is oblong, flexible and transversely oriented relative to a lengthwise fore-aft extent of the foot when placed on top of the foot during positioning the fitment on the foot in wearing the fitment on the foot. The fitment is flexible for being conformable to a three-dimensional contour of the top of the foot and preferably also to be conformable to the part of the upper or vamp of the footwear worn on the foot covering or overlying the fitment. The oblong fitment has a central base with a thickness provided by the pad that functions as a spacer which helps snug the footwear on the foot in a fore-aft or proximal-distal direction preferably thereby also preventing fore-aft or proximal-distal movement (i) of the foot within the footwear relative to the footwear, and/or (ii) of the footwear worn on the foot relative to the foot. The oblong fitment has a pair of wings extending oppositely outwardly from the central base that also have a thickness, preferably also provided by the pad, which correspondingly extend transversely along a portion of opposite sides of the foot at, along or adjacent the ankle that help snug the footwear on the foot in a side-to-side or medial-lateral direction preferably thereby also preventing side-to-side or medial-lateral movement (i) of the foot within the footwear relative to the footwear, and/or (ii) of the footwear worn on the foot relative to the foot.
Another preferred embodiment of a fitment constructed in accordance with the present invention is a width and thickness adjustable fitment assembly that has a fitment pad carrier that is oblong in shape and transversely oriented across the top of the foot upon which it is worn with the fitment pad carrier having a pocket formed therein for releasably receiving and retaining a slidable thickness-increasing fitment adjuster pad in the pocket. The fitment adjuster pad can be slide into or out of the pocket in trombone fashion to vary the width and thickness of the adjustable fitment assembly to vary the amount of snugness desired.
The fitment pad carrier is of the same or like construction as one of the preferred fitments described hereinabove having a flexible, compressible and resilient foam or fabric thickness-providing pad within that serves as a spacer to space an overlying portion of the upper or vamp of the footwear away from an underlying portion of the midfoot or ankle region of the foot during fitment use and operation. The fitment adjuster pad also is of the same or like construction as one of the preferred fitments described hereinabove that also has a flexible, compressible and resilient foam or fabric thickness-providing pad within.
During fitment adjustment, the fitment adjuster pad can be fully inserted into the pocket in the fitment pad carrier such that no part of the fitment adjuster pad extends outwardly beyond the periphery of the fitment pad carrier thereby providing increased thickness, preferably imparting two times or double the thickness, to the central base of the fitment assembly. The fitment adjuster pad can be slidably extended from the pocket causing part of the fitment adjuster pad to extend outwardly beyond the periphery of the fitment pad carrier thereby increasing the surface area of the adjustment fitment in a fore-aft or proximal-distal direction preferably also helping to further snug the footwear up with the foot in a fore-aft or proximal-distal direction. When the fitment adjuster pad is disposed in such a partly extended adjustment position, the thickness of the adjustable fitment assembly is greater than the thickness of the fitment pad carrier alone and the width of the adjustable fitment assembly is greater than the width of the fitment pad carrier alone. The fitment adjuster pad can be further extended until only a portion of the fitment adjuster pad is retained or received in the pocket such that when fully extended the thickness is about the same as the thickness of the fitment pad carrier and the width is between one and one-half and two times the width of the fitment pad carrier.
Other advantages, benefits and features of the present invention will become apparent to those skilled in the art upon reading the detailed description and viewing the related drawings.

Such a footwear comfort-enhancing fitment 40 of the present invention also is flexible, so as to be foot-conforming, and oblong, so at least part of the fitment 40 underlies an upper portion of the footwear 46 worn on a foot 44 carrying the fitment 40. The fitment 40 is formed with a footwear-snugging pad 42 that has a thickness sufficient to displace an adjacent upper portion of the footwear 46 overlying the fitment 40 to snug up the footwear 46 around the foot 44, is flexible to conform to a three-dimensionally contoured shape of an upper portion of the foot 44 carrying the fitment 40, is resilient for maintaining sufficient thickness to ensure continued snugging of the footwear 46 during months and preferably years of use of the fitment 40, and is padded or cushioned to help ensure that the fitment 40 itself is comfortable to wear.
The flexible, resilient, cushioned shoe snugging pad 42 of the fitment 40 has a thickness, T, which enables the pad 42 to help snug the footwear 46 on the foot 44 thereby advantageously helping prevent sliding relative movement between the foot 44 and footwear 46 worn on the foot 44 even when the pad 42 is substantially compressed between the foot 44 and the footwear 46 by the pad 42 functioning as a spacer 52 that spaces at least an adjacent portion of a top portion of an upper 102 or vamp 103 of the footwear 46 (
The fitment 40 is made of at least a plurality, preferably at least a plurality of pairs of, i.e., at least three, layers 66, 68 with a preferred fitment 40 having a pair of durable, flexible and resilient outer cloth or fabric layers 66, 68 and at least one thickness-providing inner layer not shown in

Where there previously was shoe-foot mislocation when the foot 44 was received within the shoe 48 without use of any fitment 40, such shoe-foot mislocation can undesirably allow relative movement between the foot 44 and shoe 48 to occur during walking, running or the like causing foot fatigue, and which can further result in rubbing, blistering, bruising, or other foot discomfort or even foot injury occurring from walking, dancing, jogging or running. Where the shoe-foot mislocation is fore-aft shoe-foot mislocation, relative movement occurs between the foot 44 and shoe 48 is in a longitudinal or fore-aft direction where the foot 44 slides or moves relative to the shoe 48 within the shoe 48 forwardly and/or rearwardly during walking, dancing, jogging or running causing foot fatigue, foot discomfort, crushing of toes of the foot 44, rubbing, blistering, bruising, callousing or the like. Such fore-aft foot-shoe mislocation can be caused by a shoe 48 being sized too large for or relative to the length of the foot 44, the length of the shoe 48 being too large relative to the length of the foot 44 even though the shoe 48 is technically of the correct shoe size, stretching of the shoe 48 that can occur over time during use of the shoe 48, and/or looseness of fit that can arise from wear of the shoe 48 during use.
While a footwear-snugging fitment 40 constructed in accordance with the present invention can be configured as an elongate, generally rectangular, flexible, cushioned shoe-snugging pad 42 having rounded corners (not shown), a shoe-snugging fitment 40 of the present invention preferably is configured with an elongate, oblong, flexible, padded shoe-snugging pad 42 having a generally oblong, preferably generally rhomboid pad body 62 with a width along its widest part sufficient to overlie at least a quarter, preferably at least one-third, more preferably at least one-half, of the width of the midfoot 60, with such midfoot width measured in a fore-aft direction and/or along a lengthwise direction of the foot 44. In order to be configured to cover or overlie that much of the width of the midfoot 60, a fitment 40 with such a cushioning compressible and flexible foot and shoe locating pad 42 of the present invention is constructed to have a relatively wide pad width of at least two and one-half inches, preferably at least two and three-quarter inches, and more preferably about three inches ±½ inch. The midfoot 60 extends transversely the width of the foot along the part of the foot 44 containing the navicular, cuneiform, talus and cuboid bones of the tarsal bones of the foot and is formed by or of these bones. Such a relatively wide pad width crucially produces a foot-snugging pad 42 of the invention having oppositely outwardly facing foot and shoe spacing and locating surfaces 64 of the pad 42 with enough surface area to space or forwardly displace a substantial part of the top front portion 56 and/or vamp 58 of the shoe 48 in a forward direction relative to the foot 44 received in the shoe 48 thereby snugging up a rear portion 74 of the shoe 48, such as preferably the heel or counter 76 of the shoe 48, against a heel 78 of the foot 44. Such a shoe-snugging pad 42 preferably also has a minimum cross-sectional thickness 50 of at least two millimeters, preferably at least three and one-half millimeters, more preferably at least five millimeters when compressed to its minimum thickness at or adjacent a center of the pad 42 crucially configuring the pad 42 with a sufficient enough thickness to space the front portion or vamp of the shoe far enough forwardly away from the front portion or midfoot of the foot to snug up the shoe on the foot preventing relative fore-aft movement therebetween and compensating for fore-aft foot-shoe mislocation (or even remedying fore-aft mislocation).
It is crucial that the fitment 40 of the present invention be constructed with such an elongate oblong shape having such a minimum thickness inboard of the edging or border 70 and/or in the center of the pad 42 when the pad 42 is maximally compressed, and configured for transverse placement as described and shown in
The fitment 40, including the pad 42, more properly and/or more accurately helps locate the foot 44 within the shoe 48 by the thickness 50 of the pad 42 helping to accommodate or take up undesired or excessive space between the shoe 48 and foot 44 that could have caused mislocation therebetween the pad 42 of the fitment helping to snug up a top front portion of the shoe 48 with a top front portion, e.g., midfoot 60, of the foot 44. Such a fitment 40 crucially and advantageously not only spaces a top front portion or part of the vamp 103 of the shoe 48 from an adjacent top front portion, preferably midfoot 60, of the foot 44 helping to snug up the front portion of the shoe 48 with the front portion of the foot 44, but in doing so the fitment 40 advantageously can and preferably does help ensure there is a gap or space between the toes 107 of the foot 44 and a forward part, e.g., of the shoe 48, such as the toebox, or other portion of the upper 102 of the shoe 48 surrounding or enclosing the toes 107 of the foot 44 thereby advantageously preventing toe-pressure, rubbing and/or crushing of the toes 107 within the shoe 48 from occurring.

When centered over and placed on or against the midfoot 60, the fitment 40 and pad 42 are configured with a wider central fore-aft foot spacing or fore-aft shoe-snugging base 55 from which narrower side foot spacing or side shoe-snugging rounded spacer wings 88, 90 oppositely outwardly extend, the fitment 40 and pad 42 are configured not only to provide fore-aft foot location compensation relative to the shoe 48 and fore-aft shoe snugging, but also to provide side-to-side or medial-lateral foot location and side-to-side or medial-lateral shoe snugging. In use and operation, when the fitment 40 and pad 42 are placed on the midfoot 60 of the foot 44 with the fitment 40 and pad 42 oriented generally perpendicularly relative to the lengthwise extent of foot 44, the flexible, padded, cushioning, resiliently compressible central base 55 of the pad 42 overlies a top front portion of the midfoot 60, e.g., center of the midfoot 60 providing fore-aft mislocation compensation and/or correction, one of the flexible, padded, cushioning, resiliently compressible wings 88 extends about and downwardly along part of one side of the foot 44, preferably along at least a portion of one side of the midfoot 60, helping provide side mislocation compensation and/or correction, such as when the foot 44 is narrower than the shoe 48, and the other one of the flexible, padded, cushioning, resiliently compressible wings 90 extends about and downwardly along part of the opposite side of the foot 44, preferably along at least a portion of the other side of the midfoot 60, also helping provide side mislocation compensation and/or correction. When the pad 42 is placed on the midfoot 60 with the pad 42 oriented generally perpendicularly relative to the foot 44, the flexible, padded, cushioning, resiliently compressible central base 55 of the fitment 40 and pad 42 overlies a top front portion of the midfoot 60, e.g., center of the midfoot 60 providing fore-aft shoe snugging, one of the flexible, padded, cushioning, resiliently compressible wings 88 extends about and downwardly along part of one side of the foot 44, preferably along at least a portion of one side of the midfoot 60, helping provide side shoe snugging, such as when the foot 44 is narrower than the shoe 48, and the other one of the flexible, padded, cushioning, resiliently compressible wings 90 extends about and downwardly along part of the opposite side of the foot 44, preferably along at least a portion of the other side of the midfoot 60, also helping provide shoe-snugging in a transverse or side-to-side direction. When the fitment 40 and pad 42 are placed on the midfoot 60 with the fitment 40 and pad 42 oriented generally perpendicularly relative to the lengthwise fore-aft extent of the foot 44, the flexible, padded, cushioning, resiliently compressible central base 55 of the pad 42 of the fitment 40 overlies a top front portion of the midfoot 60, e.g., center of the midfoot 60 helping more properly fore-aft locate the foot in the shoe and prevent relative fore-aft or front-back relative movement therebetween, one of the flexible, padded, cushioning, resiliently compressible wings 88 extends about and downwardly along part of one side of the foot 44, preferably along at least a portion of one side of the midfoot 60, helping more properly side-to-side locate the foot 44 in the shoe 48 and prevent relative sideway relative movement therebetween, such as when the foot 44 is narrower than the shoe 48, and the other one of the flexible, padded, cushioning, resiliently compressible wings 90 extends about and downwardly along part of the opposite side of the foot 44, preferably along at least a portion of the other side of the midfoot 60, also helping more properly side-to-side locate the foot in the shoe and prevent relative sideway relative movement therebetween.
When so positioned, each wing 88, 90 is configured as a spacer disposed between an adjacent one of the sides 104, 106 of the shoe sidewall 108 and an adjacent one of the sides 80, 82 of the foot 44, preferably adjacent one of the sides of part of the midfoot 60. Each wing 88, 90 spaces the adjacent corresponding side 104, 106 of the shoe sidewall 108 away from the respective adjacent portion of the side 80, 82 of the foot 44, preferably midfoot 60, thereby side snugging the shoe 48 around the foot 44. Being configured with such side-spacer wings 88, 90 that provide such side-snugging of the sides of the shoe 48 around the foot 44 help correct improper loose fit between the shoe and foot caused by the foot being too narrow for the shoe. Such a fitment 40, preferably along with its pad 42, is configured with such side-mislocation reducing spacer wings 88, 90 each of which also advantageously helps prevent side-to-side relative movement from occurring between the foot 44 and shoe 48.

Thickness-increasing add-on fitment adjuster pad 122 preferably is of substantially similar construction to fitment 40, e.g., fitment adjuster pad carrier 124, with the thickness-increasing fitment adjuster pad 122 being of flexible, resilient, compressible, and padded or cushioned construction having a pair of outer fabric or cloth layers sandwiching at least one pad-thickness providing inner layer within the fitment adjuster pad 122. Thickness-increasing fitment adjuster pad 122 is generally oval as shown in
