The present disclosure relates to footwear and, more particularly, relates to an article of footwear with an upper having a member with a support arm.
Articles of footwear usually include an upper and a sole structure. Generally, the upper can receive the wearer's foot and secure the footwear to the foot. Also, the sole structure can provide traction for the footwear. Moreover in some embodiments, the sole structure can be resiliently compressible to provide cushioning to the wearer's foot.
More specifically, the upper can include one or more sheet-like sections of material that define a cavity for receiving the wearer's foot. The upper can also include laces, straps, buckles, buttons, and other similar components for securing the footwear to the wearer's foot.
Also, the sole structure can include a midsole. The midsole can include resiliently compressible members, such as foam, a fluid-filled bladder, or other similar members. As such, the midsole can resiliently compress under the weight of the wearer or due to impact with a ground surface. This can help distribute the resulting loads across the sole assembly and/or attenuate the loads to provide cushioning.
The sole structure can additionally include an outsole. The outsole can be made from relatively high friction material such that the outsole can readily grip the ground with firm traction. The outsole can also include grooves, sipes, recesses, or other features that increase surface area of the ground engaging surface, that can channel water away from the ground engaging surface, or otherwise increase such traction for the article of footwear.
An article of footwear having a medial side and a lateral side is disclosed. The article of footwear can include a sole structure. The article of footwear can further include a first member that extends away from the sole structure. The first member can at least partially define the medial side and the lateral side. Moreover, the second member can have a body, a first support arm, and a second support arm. The body can be attached to the first member such that the first member and the body cooperate to define a void that is configured to receive a foot. The body can also be attached to the sole structure. The first support arm can be attached to the first member on the medial side, and the second support arm can be attached to the first member on the lateral side.
Moreover, an article of footwear is disclosed that can include a sole structure and a first member that extends away from the sole structure. The first member can have a lower peripheral edge that is adjacent the sole structure. Additionally, the article of footwear can include a second member with a body and at least one support arm that extends away from the body. The body can be attached to the lower peripheral edge such that the body and the first member cooperate to define a void that is configured to receive a foot. The body can also attach to the sole structure. The at least one support arm can extend away from the sole structure, and the at least one support arm can be layered on and attached to the first member.
Still further, a method of manufacturing an article of footwear is disclosed. The method can include providing a first member having a lower peripheral edge. The method can also include providing a second member having a body and at least one support arm that extends away from the body. The body can define a sole engaging surface. The method can additionally include attaching the body of the second member to the lower peripheral edge such that the body and the first member cooperate to define a void that is configured to receive a foot. Additionally, the method can include layering and attaching the at least one support arm on the first member. Still further, the method can include attaching the sole structure to the sole engaging surface of the body of the second member.
Other systems, methods, features and advantages of the present disclosure will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description and this summary, be within the scope of the present disclosure, and be protected by the following claims.
The present disclosure can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the present disclosure. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
Example embodiments will now be described more fully with reference to the accompanying drawings. As will be discussed, an article of footwear is disclosed below according to exemplary embodiments of the present disclosure. The article of footwear can be relatively lightweight. Also, the article of footwear can include a relatively small number of parts. Moreover, multiple features of the footwear can be combined into a single part. Accordingly, the footwear can be comfortable to wear. Also, the wearer is less likely to be weighed down by the footwear during running, jumping, or other ambulatory activities. Moreover, manufacturing efficiency can be increased due to the features discussed below.
Referring initially to
For reference purposes, the article of footwear 10 may be divided into three general regions: a forefoot region 16, a midfoot region 17, and a heel region 18. Forefoot region 16 can generally support forward portions of the wearer's foot, including the toes and joints connecting the metatarsals with the phalanges. Midfoot region 17 can generally support middle portions of the wearer's foot, including an arch area. Heel region 18 can generally support rear portions of the wearer's foot, including the heel and calcaneus bone. Footwear 10 can also include a lateral side 22 and a medial side 20. The lateral side 22 and medial side 20 can be disposed on opposite sides of a longitudinal axis 24 of footwear 10. The forefoot region 16 and the heel region 18 can be disposed on opposite sides of a transverse axis 26 of the footwear 10. Also, lateral side 22 can correspond with an outside area of the wearer's foot, and medial side 20 can correspond with an inside area of the wearer's foot. Forefoot region 16, midfoot region 17, heel region 18, lateral side 22, and medial side 20 are not intended to demarcate precise areas of upper 10. Rather, forefoot region 16, midfoot region 17, heel region 18, lateral side 22, and medial side 20 are intended to represent general areas of upper 10 to aid in the following discussion.
In some embodiments, the footwear 10 can have a very low total weight. As such, the footwear 10 can allow the wearer to run faster, to run longer distances with less fatigue, to jump higher, or to otherwise enhance the wearer's performance. Moreover, the footwear 10 can be sleek and can conform closely to the wearer's foot for added comfort and for aesthetic appeal. Also, the footwear 10 can include several features that provide reinforcement, robustness, and strength to the footwear 10. Accordingly, the footwear 10 can withstand high stress and can be used over a long period of time without tearing or otherwise failing.
Moreover, some embodiments of the article of footwear 10 can include a part that extends continuously from one area of the footwear 10 to a different area. For example, a part can be included that extends continuously between the medial side 20 and the lateral side 22. In additional embodiments, a part can be included that extends continuously between the forefoot region 16 and the heel region 18. Thus, this part can interconnect two opposite areas of the article of footwear 10. This configuration can help to reinforce the article of footwear 10 and also provide additional structure to the article of footwear 10. This configuration can also help to provide additional support to the wearer's foot.
In some embodiments, the part can, in essence serve two functions: helping to join an upper with a sole structure, while at the same time, providing additional structural support to the upper 12. Because this part can serve multiple functions, redundant components can be eliminated. Also, components that would otherwise be used to reinforce the footwear 10 or support the wearer's foot can be eliminated. Accordingly, the footwear 10 can be made lightweight, and yet, the footwear 10 can provide sufficient support to the wearer's foot and can be sufficiently robust.
Generally, the article of footwear 10 can include an upper 12 and a sole structure 14 that are attached together. The upper 12 can define a void 76 that can receive the wearer's foot, and the sole structure 14 can be disposed underneath the upper 12 and, thus, underneath the sole of the wearer's foot. As such, the sole structure 14 can provide traction, protect the sole of the wearer's foot, provide cushioning, attenuate impact forces, or provide other benefits.
Referring now to
The outsole 31 can include one or more pads of high friction, resiliently elastic material. Also, the outsole 31 can define a ground engaging surface 35 that engages the ground, floor, running track, or other supporting surface. The ground engaging surface 35 can include grooves, ridges, sipes, projections, cleats, or other features that increase traction, that increase flexibility of the outsole 31, or that channel water away from the outsole 31. Moreover, the outsole 31 can define an upper engaging surface 40 that faces in an opposite direction from the ground engaging surface 35. The upper engaging surface 40 can attach to the upper 12 as will be discussed. Still further, the outsole 31 can define a peripheral side surface 37 that extends between the upper engaging surface 40 and the ground engaging surface 35. In some embodiments, the outsole 31 and the sole structure 14 can incorporate one or more of the features disclosed in U.S. Patent Publication No. 2015/0068063 A1, entitled “Outsole With Stepped Projections For Article of Footwear” (U.S. patent application Ser. No. 14/025,351, which was filed on Sep. 12, 2013 and lists Bryan N. Farris as the inventor), and which is incorporated by reference in its entirety.
Referring now to
Some embodiments can include provisions for reinforcing the upper 12. In some cases, these reinforcing features may be integrated with other components. In some embodiments, a reinforcing feature may be associated with second member 52. In some cases, this reinforcing feature may be a device or component attached to second member 52.
As shown in the embodiments shown in
The first member 50 of the upper 12 will now be discussed in detail according to exemplary embodiments. As shown in
Also, the first member 50 can include an ankle opening 74 that is defined by a rim 72 and that provides access into and out of the internal void 76 within the upper 12. Additionally, the first member 50 can include a throat opening 82 that extends along the longitudinal axis 24 between the medial side 20 and the lateral side 22. The throat opening 82 can be elongate and can include a forward end 84 and a rear end 86. The forward end 84 can be disposed in the forefoot region 16, and the rear end 86 can be disposed adjacent the ankle opening 74. As will be discussed, the size of the throat opening 82 can be selectively varied. For example, the width or girth of the throat opening 82 along the transverse axis 26 can be selectively changed. As such, the footwear 10 can be widened for inserting and removing the wearer's foot from the footwear 10, and the footwear 10 can also be tightened around the wearer's foot for securing the foot within the footwear 10. Moreover, the first member 50 can include a lower peripheral edge 54, which is shown in
As shown in
The first panel 64 can also include a throat edge 78 and an upper edge 44, and the second panel 66 can include a throat edge 80 and an upper edge 48 in some embodiments as shown in
In some embodiments, the first panel 64 and/or the second panel 66 can be made from lightweight material. For example, the first panel 64 and the second panel 66 can be made from mesh-type material as represented in
In some embodiments, first member 50 can also include a collar 88. The collar 88 can be a strip of material that is attached to the first panel 64 and/or the second panel 66, adjacent the ankle opening 74. For example, the collar 88 can be folded over and attached to the upper edge 44 of the first panel 64 and the upper edge 48 of the second panel 66. In some embodiments, the collar 88 can extend continuously from the first throat edge 78 to the second throat edge 80 so as to substantially encircle the ankle opening 74 and to define the rim 72 of the opening. The collar 88 can be attached to the first panel 64 and the second panel 66 using adhesives, stitching, fasteners, or any other suitable fixation device.
Moreover, the first member 50 of the upper 12 can include a tongue 90. The tongue 90 can be disposed within throat opening 82 and can extend between the first throat edge 78 and the second throat edge 80.
For example, as shown in
Also, as shown in
Additionally, the article of footwear 10 can include a closure member 142 or securing device that can be used to selectively secure the footwear 10 to the wearer's foot. The closure member 142 can be of any suitable type, such as shoelaces, a strap, hook-and-loop tape such as VELCRO™, buttons, snaps, buckles, hooks, or any other type of closure member 142.
For example, the footwear 10 can include a shoelace 143. The shoelace 143 can alternate between the first throat edge 78 and the second throat edge 80 as the shoelace 143 extends between the rear end 86 and the forward end 84 of the throat opening 82. Also, the shoelace 143 can be secured to the first throat edge 78 and the second throat edge 80 in any suitable fashion. For example, the shoelace 143 can be received in eyelets, grommets, or loops, the shoelace 143 can be fastened around hooks, or the shoelace 143 can be attached to the first throat edge 78 and the second throat edge 80 in another way. Thus, the shoelace 143 can be tightened to make the upper 12 more narrow for securing the upper 12 to the wearer's foot. The shoelace 143 can also be loosened to make the upper 12 wider for releasing the upper 12 from the wearer's foot.
In the embodiments illustrated in
As shown in
As stated, the upper 12 can also include the second member 52, which cooperates with the first member 50 to define the void 76 of the upper 12. As will be discussed, the second member 52 can include one or more areas that attach to the first member 50. These areas of the second member 52 reinforce the first member 50. These areas can also provide additional support to the wearer's foot. Moreover, in some embodiments, the second member 52 can extend continuously between opposing areas of the first member 50 as will be discussed. Thus, the second member 52 can interconnect opposing areas of the first member 50 to distribute loads through the upper 12. Also, the second member 52 can be configured to combine certain structural features included in traditional articles of footwear. As such, the article of footwear 10 can be assembled from fewer parts than other traditional articles of footwear. Additionally, the second member 52 can reduce the weight of the article of footwear 10 as will be discussed in detail.
In some embodiments, the second member 52 can be made from a sheet of material, such as leather, suede, fabric, or other material. Also, the second member 52 can include an upper surface 101 that faces away from the sole structure 14. The second member 52 can further include a lower surface 103 that faces in an opposite direction from the upper surface 101. The lower surface 103 can engage and attach with the sole structure 14 in some embodiments.
As shown in
In some embodiments represented in
Additionally, as shown in
The second member 52 can be attached to the first member 50 such that the body 55 covers over the underfoot opening 33 of the first member 50. Also, in some embodiments, the body 55 can attach to the first member 50 along the lower peripheral edge 54 of the first member 50.
Moreover, the first arm 56 can extend along the medial side 20 of the first panel 64 of the first member 50. More specifically, the upper surface 101 of the first arm 56 can attach to the exterior surface 63 of the first member 50. In some embodiments, the first arm 56 can be long enough such that the second end 102 is adjacent the third layer 136 of the tongue 90 near the throat opening 82. Also, the first arm 56 can extend over the first member 50 such that the first arm 56 reinforces the midfoot region 17 and is substantially centered on the arch area of the wearer's foot. Accordingly, the first arm 56 can support the wearer's arch.
Additionally, the upper surface 101 of the second arm 58 can extend over and can attach to the exterior surface 63 along the lateral side 22 of the second panel 66 of the first member 50. In some embodiments, the second end 106 can be spaced from the fifth layer 140 of the tongue 90 as shown in
Furthermore, the upper surface 101 of the third arm 60 can extend over and attach to the exterior surface 63 along the forefoot region 16 of the first member 50. In some embodiments, the third arm 60 can overlap the first seam 68 such that the first seam 68 is substantially shielded from view. Moreover, the third arm 60 can be long enough such that the second end 110 is adjacent the forward end 84 of the throat opening 82. For example, the second end 110 of the third arm 60 can overlap the tongue 90 adjacent the forward end 84 as shown in
Additionally, the upper surface 101 of the fourth arm 62 can extend over and attach to the exterior surface 63 along the heel region 18 of the first member 50. In some embodiments, the fourth arm 62 can overlap the second seam 70 such that the second seam 70 is substantially shielded from view. Moreover, the fourth arm 62 can be long enough such that the second end 114 projects away from the rim 72 of the first member 50. Thus, the second end 114 can act as a pull tab and can be used by the wearer when pulling on the footwear 10 onto the wearer's foot.
Attached as such, the second member 52 can cover over and reinforce portions of the first member 50. Areas of the first member 50 between the arms of the second member 52 can remain exposed. For example, an exposed area of the exterior surface 63 is indicated at 153 in
Additionally, it will be appreciated that the upper surface 101 of the body 55 of the second member 52 can face the wearer's foot and can partially define the void 76 within the upper 12. Also, the body 55 can extend between and attach to both the first panel 64 and the second panel 66. Moreover, the body 55 can extend underneath the wearer's foot, and the first arm 56, the second arm 58, the third arm 60, the fourth arm 62 can wrap around the wearer's foot such that the second member 52 substantially cradles the wearer's foot. Accordingly, the second member 52 can provide significant support to the wearer's foot. Moreover, in some embodiments, the first arm 56 can have some rigidity such that the first arm 56 is biased to rotate about the first end 100 away from the void 76. As a result, the first arm 56 can provide lift for the medial side 20 of the first member 50 away from the sole structure 14. Stated differently, the medial side 20 can be self-supporting due to the rigidity of the first arm 56. Likewise, the second arm 58 can have some rigidity to provide lift to the lateral side 22, the third arm 60 can have some rigidity to provide lift to the forefoot region 16, and the fourth arm 62 can have some rigidity to provide lift to the heel region 18. It will be appreciated that a traditional heel counter, a toe box, or other stiffeners may not be necessary due to the second member 52. Accordingly, the part count of the footwear 10 can be reduced for reducing weight of the footwear 10 and for increasing manufacturing efficiency.
Referring now to
In some embodiments, manufacture of the footwear 10 can begin by attaching the first panel 64 and the second panel 66 together. Once attached, the tongue 90 and/or the collar 88 can be attached to the first panel 64 and the second panel 66. For example, as represented in
As described above, the forward edge 41 of the first panel 64 and the forward edge 45 of the second panel 66 can attach together to form the first seam 68. The forward edge 41 and the forward edge 45 can butt up against each other to form a butt joint at the seam 68. In other embodiments, the forward edge 41 and the forward edge 45 can overlap each other at the seam 68. Also, the first panel 64 and the second panel 66 can be attached at the seam 68 using any suitable attachment type. For example, the seam 68 can be formed using adhesives, fasteners, stitching, or another attachment device. For example, adhesive can be applied adjacent the edge 41 and/or the edge 45, and the edge 41 and the edge 45 can be pressed against each other until the adhesive dries.

In additional embodiments, the sole structure 14 can be substantially simultaneously formed and directly attached to the upper 12. Stated differently, the sole structure 14 can be molded onto the upper 12. In some embodiments, this process can incorporate one or more of the teachings disclosed in U.S. Pat. No. 3,676,542, entitled “Manufacture of Footwear,” and issued Jul. 11, 1972 to Maltby, which is hereby incorporated by reference in its entirety.
Accordingly, the sole structure 14 can be formed using a molding assembly 162. The molding assembly 162 can include a first mold 164 and a second mold member 166. The upper 12, the first mold 164, and the second mold member 166 can cooperate to define a mold cavity 168 as shown in
Accordingly, the article of footwear 10 can be very lightweight. For example, the materials used to form the first member 50 can be very lightweight and breathable. Also, a traditional heel counter, a toe box, or other stiffeners may not be necessary because the second member 52 can provide ample support for the wearer's foot, can provide lift to the first member 50, and can reinforce the first member 50. Accordingly, the footwear 10 can enhance the wearer's running, jumping, or other ambulatory activities. Also, the footwear 10 can be manufactured in an efficient manner.
