Definitions

  • the present invention relates to footwear, and more particularly to footwear incorporating a sole assembly have a plate.
  • a typical article of footwear includes an upper joined to a sole or sole assembly.
  • the sole underlies the wearer's foot and provides a ground-engaging surface that protects the wearer's foot.
  • soles are often designed to provide the desired support, cushioning and energy return.
  • footwear is available with a wide variety of different soles or sole assemblies.
  • the sole assembly incorporates a plate that is substantially more rigid than the cushioning materials incorporated into the sole assembly. The plate is designed to bend under load during an initial portion of the wearer's stride to store energy and then to return to its original shape as the load is reduced during a later portion of the wearer's stride, for example, during toe off.
  • the properties of a sole assembly are complex and depend greatly on a variety of factors, most notably the design and configuration of the plate and the cushioning materials with which the plate is combined.
  • a wide range of plated sole assemblies have been developed for a variety of different applications, such as hiking, walking, running and leisure activities.
  • the rigidity of the plate, the position of the plate within the sole assembly, the shape of the plate, the material from which the plate is manufactured, the cushioning properties of the cushioning materials (e.g. midsole), the position of the cushioning material relative to the plate and the wearer's foot are all factors that contribute to the overall properties of the sole assembly.
  • More rigid plates can be used to provide enhanced support when desired, but they can increase weight and make the sole assembly less comfortable and overly stiff for a range of applications.
  • the support and energy return properties provided by the plate can be localized or otherwise controlled to contribute to the overall characteristics of the sole assembly.
  • the cushioning materials can be designed to accommodate the plate and to give the sole assembly the cushioning, comfort and energy return characteristics desired. Too little cushioning material may not provide adequate cushioning and may reduce the comfort level of the sole assembly. On the other hand, too much cushioning material may make the sole assembly excessively thick and may reduce the effectiveness of the plate by absorbing too much of the energy returned by the plate.
  • An article of footwear includes a sole assembly have a plate disposed between top and bottom midsole layers.
  • the plate includes a heel portion, an arch portion and a forefoot portion.
  • the forefoot portion includes a medial extension that extends generally longitudinally along the medial edge of the forefoot region, a central extension that extends longitudinally through the approximate center of the forefoot region and a lateral extension that extends longitudinally along the lateral edge of the forefoot region.
  • the central and lateral longitudinal extensions are joined to one another at their forward ends.
  • the heel portion of the plate includes a peripheral region that is curved upwardly to provide a somewhat concave seat for the heel of the wearer's foot.
  • the arch portion also includes a peripheral region that extends upwardly in concert with the peripheral region of the heel portion, whereby the arch region and heel region cooperatively define a heel cradle that begins in the arch portion and extends to the rearmost end of the plate.
  • the heel cradle receives the heel portion of the top midsole layer and, when worn, receives the heel of the wearer's foot.
  • the complex curvature of the plate in the heel region also enhances the rigidity of the plate in the heel region where the force of heel strike is primarily focused.
  • an opening is defined through the approximate center of the heel region of the plate.
  • the opening may be generally oval being extended in the longitudinal direction.
  • the heel opening allows communication between the upper midsole layer and the bottom midsole layer in the approximate center of the heel region, thereby providing enhanced centering and cushioning of the wearer's foot while also reducing the weight of the plate.
  • the medial extension is curved and extends along the medial peripheral edge of the sole beginning at the forward end of the arch region and extending forwardly to at least a point under the great toe.
  • the medial extension may be offset inwardly from an extend parallel to the medial edge of the sole assembly.
  • the lateral extension is curved and extends along the lateral peripheral edge of the sole beginning at the forward end of the arch region and extending forwardly to at least a point under the small toes.
  • the lateral extension may be offset inwardly from and extend parallel to the lateral edge of the sole assembly.
  • the central longitudinal extension is generally straight beginning at the forward end of the arch region and extending forwardly to a point between the end of the medial longitudinal extension and the lateral longitudinal extension.
  • the plate in another embodiment, includes a lateral bridge extending somewhat laterally between the forward ends of the central extension and the lateral extension.
  • the bridge may have approximately the same width as the central extension and the lateral extension.
  • the central extension, lateral extension and lateral bridge cooperatively define a closed opening in the forefoot region.
  • the heel region of the upper midsole layer is disposed in the heel cradle.
  • the upper midsole layer may be supported upon the plate with its peripheral edge remaining separate from the lower midsole layer.
  • the peripheral edges of the upper midsole layer and the lower midsole layer are separated through the heel portion or separated through both the arch portion and the heel portion.
  • the peripheral edge of the plate flares outwardly to define a heel flange extending around at least a portion of the heel region of the plate.
  • the heel flange may extend along a plane.
  • the heel flange may include an upwardly facing surface that is exposed around at least a portion of the heel portion.
  • the upper midsole layer terminates short of the heel flange on the lateral side, the medial side and the rear end of the sole assembly. In such embodiments, the upper midsole layer may be adhesively joined to the upper surface of the plate, excluding the upper face of the flange.
  • the lower midsole layer is wider than the upper midsole layer in at least a portion of the heel region. In one embodiment, the lower midsole layer extends beneath the heel flange of the plate and is in direct contact therewith. As a result, the portions of the lower midsole layer beneath the heel flange provide additional cushioning and support for the wearer's foot, especially during heel strike.
  • an outsole is disposed on the undersurface of the bottom midsole layer. If included, the outsole may cover all of the undersurface or it may cover one or more portions of the undersurface.
  • the outsole may be formed by a single continuous section of outsole material or it may be formed by a plurality of separate segments of outsole material that cooperate to cover different portions of the undersurface.
  • the outsole (whether continuous or in separate parts) is secured to the undersurface of the bottom midsole layer by adhesive
  • the peripheral edges of the bottom surface of plate are exposed in the arch region.
  • the bottom midsole layer may include medial and lateral recesses that expose portions of the bottom surface of the plate.
  • the size and shape of the recesses may be selected to tune the cushioning, support and energy return characteristics of the plate, particularly in the arch region.
  • the upper, top midsole layer, plate and bottom midsole layer may have a stepped arrangement in the heel portion that is configured to provide the sole with the desired cushioning, support and energy return characteristics.
  • the top midsole layer extends outwardly beyond the lateral, medial and rear extents of the upper in the heel region.
  • the plate extends outwardly beyond the lateral, medial and rear extents of the top midsole layer.
  • the bottom midsole layer extends outwardly beyond the lateral, medial and rear extents of the top midsole layer and/or the plate in the heel region.
  • the stepped arrangement provides the sole assembly with broad support for the heel on the lateral side, the medial side and the rear while reducing the breadth of the top midsole layer to enhance the cushioning feel above the plate.
  • the current embodiments relate to a sole construction having a unique arrangement of a top midsole layer, a plate and a bottom midsole layer that provide optimal support, cushioning and energy return through the gait cycle from heel strike to toe off.
  • the plate provides the forefoot with substantial longitudinal support while still allowing a desirable amount of lateral flexibility.
  • the use of a separate medial extension and joined central and lateral extensions gives the great toe enhanced, independent flexibility while helping to maintain a greater level of lateral support for the remaining toes.
  • the heel cradle helps to center and support the wearer's foot, as well as to provide optimized energy return following heel strike.
  • the incorporation of a stepped configuration broadens the ground engaging surface to provide enhanced support and cushioning.
  • the heel flange extends outwardly over the broadened bottom midsole layer, thereby receiving support and cushioning from the additional cushioning material disposed thereunder.
  • the article of footwear 10 includes a sole assembly 12 that incorporates a top midsole layer 14, a plate 16 and a bottom midsole layer 18.
  • the sole assembly 106 may also include an outsole 50 that is joined to the bottom surface of the bottom midsole layer 18.
