Description
FIELD OF THE DISCLOSURE

This disclosure relates to footwear, and more specifically to foot supporting structures for footwear having features that improve the comfort for the wearer during standing, walking and running. The disclosure has particular applicability for use in connection with reducing or eliminating pain from plantar fasciitis and will be described in connection with such utility. Although other utilities are contemplated.


BACKGROUND AND SUMMARY

Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue which supports the arch of the foot. It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. Pain also is frequently brought on by bending the foot and toes up towards the shin. The pain typically comes on gradually, and it affects both feet in about one-third of cases.


The cause of plantar fasciitis is not entirely clear. Risk factors include overuse, such as from long periods of standing, an increase in exercise, and obesity. It is also associated with inward rolling of the foot, a tight Achilles tendon, and a sedentary lifestyle. It is unclear if heel spurs have a role in causing plantar fasciitis even though they are commonly present in people who have the condition. Plantar fasciitis is a disorder of the insertion site of the ligament on the bone characterized by micro tears, breakdown of collagen, and scarring.


Most cases of plantar fasciitis resolve with time and conservative methods of treatment. For the first few weeks, those affected are usually advised to rest, change their activities, take pain medications, and stretch. If this is not sufficient, physiotherapy, orthotics, splinting, or steroid injections may be options. If these measures are not effective, additional measures may include extracorporeal shockwave therapy or surgery.


Between 4% and 7% of the general population reportedly has heel pain at any given time: about 80% of these are due to plantar fasciitis. Approximately 10% of people reportedly have the disorder at some point during their life.


Cuboid pads have been used in podiatry and orthotic construction for many years. Cuboid pads are used to treat cuboid foot pain and prevent the cuboid bone from excessive plantar movement during walking. Referring to FIGS. 1 and 2, cuboid 100 is a bone on the lateral side of the foot 104 and is jointed at its heelward or posterior end to the calcaneus 106, and to the bases 108, 110 of the 4th and 5th metatarsals at its toeward end.


The peroneus longus tendon 112 is the connection of the peroneus longus muscle (on the lateral side of the lower leg) to the insertion points on the inferior surface 116 of the human foot. From the lateral side 118, the tendon 112 makes a turn medially directly under the cuboid 100. From the cuboid 100 to the medial side 120 of the foot 104, the tendon 112 connects to the base 122 of the 1st metatarsal and to the medial cuneiform bone 124. Its action is to stabilize the entire 1st ray 126 to the ground during the second half of single support phase. Tendon 112 uses the cuboid 100 as a fulcrum point to provide mechanical advantage for the 1st ray 126 support against ground reactive force. On the inferior surface of cuboid 100, there is a notch 130 known as the peroneal groove or notch, and this is where the tendon 112 changes direction from a vertical to horizontal direction.


In accordance with the present disclosure, we provide a foot supporting surface such as a footwear sole with a cuboid pad having a groove or notch on a superior surface of the pad and aligned with the axis of pull of the peroneus longus tendon. The notch or groove on the superior surface of the cuboid pad, which in a preferred embodiment is in the form of a flattened cylindrically shaped groove or notch, essentially the location mirrors the peroneal sulcus of the cuboid, thus accommodating the peroneal tendon, to permit its normal function during weightbearing activities. The orientation of the groove or notch in the cuboid pad is critical to its function. The axis of the groove or notch on the cuboid pad runs obliquely from the lateral to medial side of the foot and is arranged to align with the location of peroneus longus tendon so as to direct the angle of pull of the peroneus longus tendon to the base of the 1st metatarsal cuneiform. Even though the cuboid pad is oriented to run generally from heel to toe, the groove or notch on the superior surface of the cuboid pad is obliquely angled at about 50° to an imaginary line drawn from heel to toe and oriented laterally to medially.


The cuboid pad is placed on the superior or outer surface of the footwear sole in the midfoot area and is configured to lie essentially immediately below the central inferior cuboid bone. The cuboid pad ranges in thickness from about 0.5 to about 2 mm at its maximum height. Cuboid pads have been used in the past for addressing various foot pain symptoms. However, prior art cuboid pads were all shaped as a convex surface extending into the interior of the footwear.


By providing an obliquely running concave surface, or groove or notch on the superior surface of the cuboid pad, in accordance with the present disclosure, we provide a cuboid pad and its advantages without restricting the motion of the perineal tendon.


More particularly, in accordance with the present disclosure there is provided a human shoe sole having foot supporting upper surface including a first region for supporting the first, second, third, fourth and optionally fifth metatarsal heads of the foot of the wearer when the human shoe sole is worn; a second region for supporting the wearer's heel when the shoe sole is worn; and a section bridging the first section and the second section, wherein the shoe sole includes a cuboid pad immediately forward the second section configured to underlie essentially the central interior cuboid bone of the wearer, wherein the cuboid pad includes an obliquely running concave surface or groove or notch on a superior surface of the cuboid pad arranged to align with the peroneus longus tendon of the wearer.


In one aspect the groove or notch on the superior surface of the cuboid pad is in the form of a flattened cylindrically shaped groove or notch.


In another aspect the groove or notch on the superior surface of the cuboid pad runs at about 50° to an imaginary line bisecting the human shoe sole, and oriented laterally to medially of the shoe sole.


In yet another aspect, the human shoe sole is formed as an integral structural element of a shoe or boot.


In a further aspect the human shoe sole is formed as an insole of a shoe or boot.


In yet another aspect, the human shoe sole is formed as a separate removable element of a shoe or boot product.


In a further aspect the human shoe sole is formed as a sock liner or removable insole for a shoe or boot.


In another aspect the human shoe sole is formed as an aftermarket insole for a shoe or boot.


In a further aspect the human shoe sole is formed as a custom or prefabricated foot orthotic.


In yet another aspect the human shoe sole is formed directly into the foot supporting surface of a shoe or boot.


1 In a further aspect, the human shoe sole is part of a shoe which comprises a sandal, a flip-flop or a molded footwear product.


In yet another aspect, the cuboid pad is 1-2 mm at its highest point.


In a still further aspect, the cuboid pad groove or notch is about 1 mm deep measured from a high point on the cuboid pad.

FIG. 4 is a perspective view of the footwear pad of FIG. 3; and



FIG. 5 is a top plan view showing details of a footwear sole of FIG. 3, with contour lines taken at 0.2 mm superimposed thereon.





DETAILED DESCRIPTION

As used herein the term “foot supporting surface” is used interchangeably with “sole” and “inner sole”, and may include full, or three quarter soles, and half soles or heel pads and may be a structure built into or forming an integral element of a footwear product such as an insole board, or as a separate element, including, e.g. a sock liner or removable insole, an after-market insole device, or a custom or prefabricated foot orthotic, which may be inserted into a footwear product post-manufacture. The element also may be molded into or formed in the foot supporting surface of a shoe such as sandal or flip-flop or other form of molded footwear product.


Referring to FIGS. 3-5 of the drawings, there is disclosed a left foot footwear sole 10 having a cuboid pad in accordance with the present disclosure. It will be understood by one skilled in the art that the right footwear sole will be a mirror image of the illustrated left footwear sole.


The footwear sole has a heel section 12 which starts at the back of the sole 10 and runs forward towards the front of the sole and is configured to underly the heel of the wearer's foot and includes medial and lateral regions 11 and 13, respectively, corresponding to the inner and outer sides of the sole 10. The forefront section 16 essentially starts at point 18 where the head of the first metatarsal head of the wearer's foot overlies the sole 10. A midsection 14 bridges the heel section 12 and the forefoot section 16 and is configured to underly the arch of the wearer's foot. The forefoot section 16 includes a depression or area of reduced support 30 configured to underlie the first metatarsal head of the wearer, i.e., in accordance with the teachings of U.S. Pat. No. 8,166,674, issued May 1, 2012 to Howard J. Dananberg, one of the inventors hereof, the contents of which are incorporated herein by reference The region of depressed area 30 may be formed of a resiliently deformable material that offers less resistance to downward movement than the regions surrounding the depressed area 30, or may be formed as a depression or contour.


Insole 10 includes a heel cup 35 made in accordance with the teachings of our prior U.S. Pat. No. 10,702,008, issued Jul. 7, 2020, the contents of which are incorporated herein by reference. Heel cup 35 is in the form of an asymmetric generally round shaped depression and includes a forward depressed extension region 38 on its medial side, which serves to reduce pressure on the plantar facia of the wearer's foot as it travels from its attachment on the medial calcaneus to the proximal phalanges. Heel cup 35 typically is 1-4 mm deep at its lowest point, preferably 2-3.5 mm deep, more preferably 2.5-3 mm deep.


In accordance with the present disclosure, we provide a cuboid pad 50 immediately forward the heel cup 35 on the lateral side of the heel cup, i.e., on the lateral side in the midfoot region. Cuboid pad 50 is configured to fall essentially immediately below the central inferior region of the cuboid bone 100 (see FIGS. 1 and 2) of the wearer. Cuboid pad 50 typically is about 20 mm long, and 1-2 mm at its highest point, preferably 1-1.5 mm high, more preferably 1-1.25 mm high. Cuboid pad 50 includes a groove or notch 54 about 12.5 mm wide, and about 1 mm deep, running from the lateral to medial side of the foot at an oblique axis angle of 50° relative to an imaginary line 52 running from the center of the heel section 12 to the center of the forefoot section 16 of the footwear sole 10, and is arranged to align with the peroneus longus tendon of the foot of the wearer. While the cuboid pad 50 is oriented slightly oblique to imaginary line 52 from the center of heel section to the center of the toe section of footwear sole 10, groove or notch 54 on the superior surface of the cuboid pad 50 is oriented to run close to 90° perpendicular to the elongate orientation of the cuboid pad 50 and is oriented essentially to run in a direction of within about 50° to a lateral to medial orientation. As so formed, the peroneal tendon of a wearer is accommodated within the groove or notch 54 and is free to assume its normal function. Thus, we are able to correct for over supination, without causing or exacerbating plantar fasciitis.


Various changes may be made in the foregoing disclosure without departing from the spirit and scope thereof. For example, while the footwear sole has been described as comprising a full footwear sole, underlying the heel, arch and forefoot regions of the wearer's foot, the footwear sole could comprise a shortened sole such as a ¾ sole, i.e., essentially extending from the heel to line 60. Also, the foot supporting surface having a cuboid pad in accordance with the present disclosure may be formed in a heel piece only, i.e., essentially extending from the heel to line 62. The cuboid pad and heel depression also may be formed in a molded footbed such as for a flip-flop or sandal.


Various other changes may be made without departing from the spirit and scope of the present disclosure.
