An article of footwear includes an upper, and multiple cushioning components that are attached to a ground-facing surface of the upper. The cushioning components are spaced apart from one another so that the ground-facing surface of the upper is exposed between the cushioning components and the cushioning components at least partially form a ground contact surface. At least one of the cushioning components includes a bladder element with a fluid-filled cavity. A method of manufacturing an article of footwear comprises attaching cushioning components to a ground-facing surface of an upper so that the cushioning components are spaced apart from one another, the ground-facing surface of the upper is exposed between the cushioning components, and the cushioning components at least partially form a ground contact surface, wherein at least one of the cushioning components includes a bladder element with a fluid-filled cavity.

A futuristic shoe with true energy return based on enhanced heel-lift, optimized shoe springs (40% reduction in maximum foot impact), practical precise automatic electronic gear changers, novel powerful shoe impact chargers, improved pulley electronic actuators, novel low-impact much stronger springs (featuring the novel use materials such as Kevlar, Spectra Shield, and fiberglass), novel remarkably stronger, more flexible, and tougher structures, and multiple designs for enhanced heel-lift and to prevent excessive toe sink. These designs require linkages and two improved hingesone with enhanced natural hinges and a second with tied cogged hinges. There is a rotating-arms enhanced optimal spring, which when combined with the tied cogged hinges, results in optimal foldable arrays for deployment in outer spaceand which gives a smart energy return knee brace. These novel capabilities promise a wide range of additional applications such as robotics, prosthetics, orthotics, springs, aerospace, automobiles, body armor, and earthquake retrofitting.

A footwear sole includes an outsole assembly having a heel outsole, a forefoot outsole spaced axially apart from the heel outsole by an arch gap, and a sidewall extending between the heel outsole and the forefoot outsole. The sidewall has an elevated bottom edge extending axially along the arch gap on each of a medial and lateral side of the outsole assembly. The footwear sole further includes a support frame in the outsole assembly. The frame has an arch support surface extending axially along the arch gap at an elevation below at least a portion of each bottom edge. The footwear sole further includes a cushioning midsole in the outsole assembly and extending along the arch gap atop the arch support surface.

A shoe with spikes is disclosed. The shoe includes an accommodation seat, at least one moving plate, a transmission module, a plurality of posts, a plurality of spikes, and a shoe plate. The accommodation seat includes a chamber. The moving plate is disposed in the chamber and controlled to move between a first position and a second position, and includes a plurality of push members. The transmission module is configured to move the moving plate. The posts extend from the accommodation seat toward the ground. The spikes are fixed to the posts and extend out of the chamber. When the moving plate is in the first position, the spikes protrude out of the shoe plate relative to the ground. When the moving plate is moved to the second position, the push members push the shoe plate, and the spikes do not protrude out of the shoe plate.

Articles of footwear including a midsole having a winding wrapped around at least a portion of the midsole. A midsole may include a core and a winding wrapped around the core to form a plurality of loops. Each loop of the winding may include a portion extending across a top surface of the core and a portion extending across a bottom surface of the core. The loops of the winding may protrude from the top surface of the core and/or the bottom surface of the core. Methods of making a midsole having a winding are also discussed.

The present invention relates to a shoe with a superior wearing sensation that is equipped with an anti-slip structure to forward comfort and safety in a watery place, and more specifically, to an aqua shoe including an upper that covers an instep from above, an insole part that connects to the lower part of the upper and an outsole part which is integrated by adhesion with the insole part and the upper and which is supported by an outsole surface, wherein the outsole part is equipped with an anti-slip structure in which a plurality of suction parts are arranged while a suction part includes a cup that tightly contacts along the cup rim to the ground surface to provide, by being compressed, suction force and a protuberance that protrudes downward from the center of the cup.

An article of footwear may have an upper and a sole structure secured to the upper. The sole structure has a plurality of support elements, and each of the support elements include a shell and a core. The shell defines an interior void and is formed from a polymer material that extends around substantially all of the void. The core has a shape of the void and is located within the void, with at least a portion of the core being a polymer foam material. The polymer foam material of at least two of the support elements may have different densities.

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer; and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.

The present disclosure provides a footwear technology system including a multilayer shoe sole system. The multilayer shoe sole insert can include a lower outsole layer, a midsole layer, and an upper insole layer, wherein the midsole layer includes a plurality of pins extending from the bottom surface of the midsole layer, wherein the pins engage with the pin holes in the outsole layer. The system can include a dynamic upper foot retention system that moves in harmony with the foot's optimal natural movement. The dynamic upper foot retention system can include a top component connecting the lace area to the sole system, and back component that connects the upper heel area to the sole system, wherein when the laces are tightened, the force is directed towards the heel securing the foot to the shoe without forcing the arch down or constricting the raising of the foot arch.

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.
