Footwear with flexible auxetic sole structure
An article of footwear may include a sole structure comprising an outer member and a plurality of ground engaging members, including a first ground engaging member. The ground engaging members extend substantially downward from the outer surface of a sole structure. Ground engaging members, or cleats, may be auxetic structures that can increase their dimensions in a direction that is orthogonal to the direction of applied force or tension. The ground engaging members may comprise a series of faces joined along hinge portions that allow ground engaging members to flatten and expand significantly. The first ground engaging member may have a substantially three-pointed star-shaped pyramidal structure. The outer member may have a more elastic material than the material comprising the faces of ground engaging member. The outer member may have an inner surface with apertures that correspond with the ground engaging members of the outer surface.
CUSHIONING SOLE FOR FOOTWEAR
A cushioning sole for footwear includes a heel portion, an opening, and a cushioning slide. The heel portion includes a top surface and a bottom surface. The opening extends vertically through the heel portion from the bottom surface to the top surface. The cushioning slide is disposed in the opening and extends out from the top surface and out from the bottom surface.
Shoe with elastically flexible extension
A footwear article includes a foot-attachment structure configured to attach to a foot, and longitudinally opposite front and rear ends. The footwear article further includes a downward-facing exposed sole surface. A cantilever extension, in a natural condition, adjoins the sole surface at a junction, and projects rearwardly and downwardly from the junction. The extension has a proximal end and a distal end that are longitudinally opposite each other. The extension is supported at only the proximal end. The extension is configured to elastically resist upward rotation of the extension toward the sole, and is configured to be pushed upward toward the sole by the upward force.
Extruded Components For Articles Of Footwear And Methods Of Making The Same
Extruded components for articles of footwear and methods of making such articles of footwear are disclosed. A carrier can be formed from a first material, the carrier including an attachment surface configured to attach to an upper and a receiving surface having a plurality of receptacles. A second material can be extruded into a plurality of the receptacles to form cushioning elements of a sole.
Footwear devices
Footwear devices having various shock absorbing configurations situated in the heal of the footwear and a plurality of regions on the bottom of the footwear defined by a plurality of compressibilities.
SOLE STRUCTURE FOR AN ARTICLE OF FOOTWEAR HAVING A NONLINEAR BENDING STIFFNESS WITH COMPRESSION GROOVES AND DESCENDING RIBS
A sole structure for an article of footwear comprises a sole plate that has a foot-facing surface with a forefoot portion, and a ground-facing surface opposite from the foot-facing surface. The sole plate has a plurality of grooves extending at least partially transversely relative to the sole plate in the forefoot portion of the foot-facing surface, and a plurality of ribs protruding at the ground-facing surface, extending at least partially transversely relative to the sole plate, and underlying the plurality of grooves. At least some grooves of the plurality of grooves are configured to be open when the sole structure is dorsiflexed in a first portion of a flexion range, and closed when the sole structure is dorsiflexed in a second portion of the flexion range that includes flex angles greater than in the first portion of the flexion range.
ENERGY RETURN, CUSHIONING, AND ARCH SUPPORT PLATES, AND FOOTWEAR AND FOOTWEAR SOLES INCLUDING THE SAME
Support plates, and footwear soles and articles of footwear containing the same. The support plate generally may provide one or more of heel cushioning, arch support in a midfoot region of the support plate, and integral medial and lateral legs extending from the midfoot region of the support plate towards an anterior end of the support plate. An article of footwear may include a support plate at least partially embedded within a sole assembly, such as a midsole thereof. The support plate may be configured to provide energy return and arch support to a wearer of the article of footwear. The support plate may include a domed structure with radially extending arms extending from a central heel portion, where the domed structure provides heel cushioning to the wearer when a force is transmitted through the midsole to the domed structure.
Footwear with interchangeable sole structure elements
A shoe may comprise an upper and a sole structure that includes a plurality of support elements located in a plantar region. Each of the support elements may be non-destructively removable from and replaceable into the sole structure. The shoe may comprise a plurality of sensors configured to measure force exerted in a footbed region of the article of footwear, as well as a processor communicatively coupled to the sensors. The processor may be configured to receive input indicative of forces measured by the sensors and to transmit data based on that input. Methods utilizing the article may include removing a support element and replacing the removed support element with a replacement support element.
Sole structure for an article of footwear
A sole structure of an article of footwear has a support assembly structure including a flexure element and an upper support element. The flexure element may have a central portion located between first and second ground-contacting or lower regions, wherein the central portion may have a downwardly concavely-curved shell-like region. The flexure element also may have first and second flanges extending upward from the first and second lower regions, respectively. The upper support element is positioned above the central portion and between the first and second flanges of the flexure element. When a vertical compressive load is first applied to the upper support element, the upper support element moves vertically relative to the first and second flanges. An article of footwear having the sole structure attached to an upper is also provided.
Sole structure for an article of footwear
A sole structure for an article of footwear includes one or more outsole portions. At least some of these outsole portions include a plurality of alternating upward-facing and downward-facing elongate channels. The channels may have a base and two sidewalls, with adjacent channels sharing a common sidewall. The bases of the downward-facing channels form an upper surface of the outsole portion and the bases of the upward-facing channels form a lower surface of the outsole portion. The sidewalls are arranged at non-perpendicular angles to the upper surface. A first outsole portion has a pressure-versus-strain curve having a local maximum at a trip point pressure value and a first strain value and wherein the pressure-versus-strain curve has a change in strain of at least approximately 10% before a second occurrence of the trip point pressure value is reached. An article of footwear having the sole structure attached to an upper is also provided.
