A sole structure for an article of footwear may include a carrier and a frame. The frame may include walls that define cells. The carrier may cover the frame. The frame may be joined to and located on a top side of the carrier.

A footbed for a modular shoe system, a modular shoe system, and an interlocking fastener system for a footbed or for a modular shoe system, are provided. The interlocking fastener system includes a plurality of interlocking elements on a footbed configured to interlock with a plurality of complementary interlocking elements on a shoe base to releasably secure the footbed to the shoe base.

Sole structures, foot support systems, articles of footwear, and/or other foot-receiving devices include: (a) a first footwear component having a ground-facing surface, wherein a forefoot portion of the ground-facing surface includes arched medial and lateral surfaces and (b) a second footwear component having an upper-facing surface, wherein a forefoot portion of the upper-facing surface includes arched medial and lateral surfaces that face (and optionally contact) the respective arched medial and lateral surfaces of the first footwear component. The first and second footwear components are movably engaged together such that: (a) the arched medial surface of the first footwear component moves with respect to and along the arched medial surface of the second footwear component and (b) the arched lateral surface of the first footwear component moves with respect to and along the arched lateral surface of the second footwear component.

A sole structure for an article of footwear may include a carrier and a frame. The frame may include walls that define cells. The carrier may cover the frame. The frame may be joined to and located on a top side of the carrier.

Provided is a walkable shoe having a glass-like appearance. The shoe has a heel portion, a sole portion provided on the heel portion, and an upper portion provided on the sole portion; wherein the heel portion and the sole portion are made almost entirely of an organic glass, and the upper portion is made almost entirely of an organic glass.

Articles of footwear include one or more expandable lugs (e.g., inflatable lugs) to hold at least some footwear component parts together. The expandable lug(s) may be included as part of an impact force-attenuating component (e.g., a fluid-filled bladder) for the article of footwear. The expandable lug(s) extend into receptacle(s) provided in a foot support component in an unexpanded (e.g., deflated or low-pressure) condition. Once within the receptacle(s), the expandable lug(s) are changed to an expanded (e.g., inflated or high-pressure) condition. The expanded lug(s) engage bearing surfaces provided inside the receptacle(s) to prevent the lugs from pulling out of the receptacles. The use of such expandable lugs for securing footwear component parts together may enable easy assembly of footwear components without use of adhesives and/or separate hardware components, which can enhance the recyclability, sustainability, and environmental friendliness of articles of footwear and their production methods.

This disclosure concerns a shoe system including at least three separable and interchangeable components. The shoe system includes an inner layer, an intermediate layer, and an outer layer. These three components are separable layers which, when assembled and worn by the user, are nested within each other, retaining the user's foot inside the inner layer. The intermediate layer and the outer layer may have friction features which interlock together when the shoe system is assembled. The intermediate layer and the outer layer may have match features which match in some substantially recognizable way to indicate to the user that the intermediate layer is properly assembled within the outer layer.

Describes are support elements for a sole of a shoe, in particular a sports shoe, a sole and a shoe with such a support element, as well as a method for the manufacture of a support element. As examples, the support element includes a first partial member formed of a first material, and a second partial member formed of a second material. The first partial member is mechanically joined to the second partial member in a connection region, wherein the connection region is configured to allow the first partial member to rotate or slide relative to the second partial member. The first partial member, the second partial member, and the connection region can be co-molded and joined together in a single fabricating step.

The invention discloses a pair of sports shoes comprising a shoes body, a pressure generating device, a humidity sensor, a controller and a switch valve. A shoes chamber is provided at the heel of the shoes body, and the pressure generating device is arranged in the groove chamber. The upper work end of the pressure generating device is in contact with the lower surface of the insole of the shoes body; the humidity sensor is setted at the upper surface of the insole of the shoes body; the humidity sensor, the controller and the switch valve are electrically connected in turn, and the pressure generating device supplies power to the humidity sensor, the controller, and the switch valve, respectively; the controller controls the pressure generating device to stop or start energizing the solenoid valve tongue of the switch valve to close or conduct the gas passage.
