Disclosed are embodiments for a dynamic footwear cushioning system. One example embodiment includes: setting a cushioning level for cushioning material in accordance with a first setting; and altering, in dependence upon an environmental condition change, the cushioning level for the cushioning material in accordance with a second setting.

An article is provided and includes a first ballistic particle impenetrable material, which is formable into a pack and a second material, which is formable into an enclosure for the pack, the enclosure having an interior facing surface in abutment with a substantial entirety of an exterior of the pack.

A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures.

A sole structure may include chambers and a transfer channel containing an electrorheological fluid. Electrodes may be positioned to create, in response to a voltage across the electrodes, an electrical field in at least a portion of the electrorheological fluid in the transfer channel. The sole structure may further include a controller including a processor and memory. At least one of the processor and memory may store instructions executable by the processor to perform operations that include maintaining the voltage across the electrodes at one or more flow-inhibiting levels at which flow of the electrorheological fluid the through the transfer channel is blocked, and that further include maintaining the voltage across the electrodes at one or more flow-enabling levels permitting flow of the electrorheological fluid through the transfer channel.

An article of footwear includes a midsole, an upper disposed above the midsole, and an outsole disposed below the midsole. The midsole includes a unitary lattice structure having an upper side and a lower side, wherein the upper side is a user-facing side and the lower side is a ground-facing side. The midsole further includes an upper rim integrally formed with the unitary lattice structure. The upper rim extends around an upper perimeter defined on the upper side of the lattice structure.

A shoe includes a first plate and a second plate that are located in a portion of the shoe between an upper and an outsole of the shoe, and a nest formed as a bag filled with one or more gasses located between the first plate and the second plate. The shoe may further include one or more springs located in cavities in the gas filled nest for biasing the first plate and the second plate apart from each other. Pods may be located within the openings in the center of the springs, and the pods may be filled with one or more gasses. The pods may protrude from a bottom or a top surface of the nest. Spring sandwiches including one or more springs positioned between plates may be constructed and placed in various portions of a shoe. The shoe may also include piping with lights.

A wearable step-counting shoe includes a shoe body and a pedometer. The shoe body includes a shoe sole having opposite inner and outer sides, and a groove surface defining amounting groove. The pedometer is removably disposed in the mounting groove and includes a pedometer body having opposite first and second faces and configured to detect and record the number of steps taken by a user, and a screen disposed on the second face and configured to display the detected number of steps. An engaging unit is provided to fix the pedometer on the shoe body, and includes a first engaging portion provided on the groove surface, and a second engaging portion provided on the pedometer and releasably engageable with the first engaging portion.

A lace-receiving assembly includes a substrate, a first sheet, and a lace guide. The substrate includes a first surface and a second surface opposite the first surface. The first sheet includes a third surface and a fourth surface opposite the third surface. The third surface is bonded to the first surface to define a channel extending between the substrate and the first sheet. The lace guide is disposed within the channel.

A sole structure for an article of footwear comprises a midsole system with a plurality of cushioning units, each having multiple cushioning layers configured to work together as a system to absorb a compressive load, such as a dynamic compressive load due to impact with the ground, in stages of progressive cushioning according to the relative stiffness values of the layers. Various midsole systems disclosed include isolated cushioning units, linked cushioning units, sole layers having stanchions interfacing with the midsole system, midsole systems with sole layers having keyed and unkeyed portions overlying a bladder, and midsole systems with vertically-stacked cushioning units disposed in inverted relationship to one another.

A sole structure for an article of footwear comprises a midsole having four stacked polymeric sheets bonded to one another to define a first cushioning layer, a second cushioning layer, and a third cushioning layer. Each cushioning layer comprises a sealed chamber retaining gas in isolation from each other sealed chamber. Bonds between adjacent ones of the sheets are arranged such that the third cushioning layer is stacked directly above the first cushioning layer with the second cushioning layer bordering both the first cushioning layer and the third cushioning layer, and the sealed chamber of the second cushioning layer includes a plurality of elongated segments each extending lengthwise across a longitudinal midline of the midsole at a respective acute angle to the longitudinal midline.
