Definitions

  • the present disclosure relates generally to articles of footwear, and, more particularly, to articles of footwear having foot support members.
  • Ankle stability is a key and critical need from athletes and users who deal with lateral motion.
  • Athletes and users take a tremendous amount of time and effort to tape and spat their feet, as well as add additional ankle and foot support braces.
  • the ankle support systems add weight to a footwear system in which lightness is highly desired.
  • Injuries to the ankle are estimated to account for 15-20% of all musculoskeletal injuries, with approximately 85% being ankle sprains.
  • the most common mechanism of injury is excessive Inversion, coupled with Plantar Flexion - approximately 75-80% involve the lateral ligament complex, primarily the Anterior Talofibular Ligament.
  • ankle sprains occur in 40-100ms.
  • reported latency of 69-85ms with approximately 90-110ms to reach half max force, and an average of 250ms to reach peak torque generation, the body is not able to adequately respond to an unexpected inversion.
  • the stance phase lasts 200-250ms, and the calf muscles are activated approximately 150ms prior to heel impact, allowing the ankle adequate time to stabilize.
  • both bracing (lace-up and semi-rigid) and taping have been shown to reduce both the frequency and severity of ankle sprains during athletic activities.
  • Semi-rigid braces tend to have a more positive effect for individuals with a history of ankle sprains than for athletes without history.
  • lacing and taping methods currently used are time consuming and a waste of resources.
  • the user cuts off and discards the taping. This process increases the time and cost of providing support for the foot and ankle during athletic activities.
  • improvements to support members that brace the foot and ankle of a person wearing the bracing are beneficial. From EP 0948910 A2 , there is known a snowboard boot, which has an asymmetrical support member.
  • the support member has a respective upper and lower portion which are connected by a strap portion. Said document constitutes the preamble of claim 1.
  • a brace for a shoe is further known from US 2006/0283048 A1 .
  • An adjustable tension ankle support is described in WO 89/10731 .
  • a snowboard boot with removable ankle support is also described in US 2003/0115777 A1 .
  • the present invention provides an article of footwear having the features defined in claim 1. Further preferred embodiments are defined in the dependent claims.
  • foot may refer to a portion of the human foot, a full human foot, and to the ankle. Various portions of the foot include, but are not limited to, the forefoot, midfoot, upper foot, heel, and ankle.
  • the terms “medial” and “medial side” refer to the inner side of a foot extending from the large toe to the heel, and the terms “lateral” and “lateral side” refer to the outer side of the foot extending from the small toe to the heel.
  • user may refer to a person wearing an article of footwear or another person such as an athletic trainer. The user may adjust the article of footwear to apply compression and support to the foot as described herein.

  • the top plate 1960 of the brace member 1930 is triangular in shape and includes a curved upper edge 1962, an inner face 1966, and an opposite outer face 1968.
  • the inner face 1966 provides a generally flat support surface that faces the lower leg/foot of the wearer and provides support to the lower leg/foot of the wearer when lateral forces act against the top plate 1960.
  • the brace members 1930 are configured to fit within closed pockets 1927 in the shoe upper 1925 (see FIGs. 19B and 19C ).
  • the pockets 1927 are not open to the foot cavity or the exterior of the article of footwear 1910. Accordingly, the brace members 1930 are embedded between an interior and exterior layers of the shoe upper 1925 where the pockets 1927 are formed.
  • FIG. 19B shows the shoe upper 1925 with the exterior layer 1929 that forms the outside of one of the pockets 1927.
  • FIG. 19C shows the exterior layer 1929 as transparent such that the pocket 1927 is exposed with the brace member 1930 in the pocket. Because the brace members 1930 are completely enclosed within the pockets 1927, the foot 1999 of the wearer is not in direct contact with the brace members 1930. Additionally, the inner walls of the foot cavity may include padding along the pockets 1927 to cushion the foot of the wearer from the relatively hard brace members 1930.
  • the article of footwear 1910 may include support belts 1970.
  • the support belts 1970 are positioned within the support cavity and are comprised of a generally inelastic woven material, such as a woven polyester or nylon material.
  • One end 1972 of each support belt 1970 is fastened to the top plate 1960 and an opposite end 1974 of the support belt 1970 is coupled to some portion of the upper 1925, such as the eyelets 1928 of the article of footwear 1910.
  • a slot (not shown) is formed on the inner layer of the shoe upper 1925 that allows the support belt 1970 to extend through the inner layer of the shoe upper and be fastened to the top plate 1960 of the brace member 1930.
  • the support belt 1970 may be fastened to the top plate 1960 using any of various means fastening means, such as adhesives, welding or mechanical fasteners (e.g., rivets, screws, etc.). As shown in FIG. 19A , the support belts 1970 generally extend downward from the top plate 1960 as a narrow strip of material, under the insole (and thus under the foot 1999), and back to a perimeter of the tongue slot 1929 (e.g., to the eyelets 1928). Thus, one end of each support belt 1970 is positioned on the lateral side of the article of footwear 1910, and the opposite side of the support belt is positioned on the medial side of the article of footwear 1910.
  • fastening means such as adhesives, welding or mechanical fasteners (e.g., rivets, screws, etc.).
  • FIG. 19A the support belts 1970 generally extend downward from the top plate 1960 as a narrow strip of material, under the insole (and thus under the foot 1999), and back to a perimeter of the tongue slot 1929 (e.g., to the eyelets 1928).
  • the brace members 1930 prevent unnatural lateral twisting of the ankle, but allow for natural forward pivoting of the ankle (such as that experienced during walking or running).
  • the C-shaped structure of the stem 1950 allows the brace member 1930 to easily bend forward in the direction of arrow 1933 (see FIGs. 19A and 19D ), when the wearer walks or runs.
  • This forward bending action is primarily experienced at the inflection point 1952, which is the point at which the brace member 1930 is designed to bend.
  • the resilient nature of the brace member 1930 allows the stem 1950 to return to its equilibrium position, as shown in FIG, 19A .
  • the brace member 1930 has very little impact on the foot 1999 of the wearer during natural running or walking motions.
  • the brace member 1930 provides support to the foot of the wearer and helps prevent extreme twisting of the ankle.
  • the leg of the wearer presses against the top plate 1960.
  • the brace member 1930 is not designed to easily bend in the lateral or medial direction. Instead, the brace member 1930 is only designed to easily bend in a forward direction 1933 at the inflection point 1952.
  • the width and shape of the brace member 1930 at the inflection point 1952 means that the brace member 1930 significantly resists lateral bending (in the direction of arrow 1935). This results in an opposing force against the leg of the wearer when the ankle begins to twist. If this opposing force is strong enough, the wearer may avoid or reduce the severity of an ankle sprain from lateral or medial twisting of the ankle.
