A mid sole arranged on an outsole having a tread surface, the mid sole including: an upper layer and a lower layer, wherein one of the upper layer and the lower layer includes a layer of a first foamed body having a thermoplastic resin component; in another one of the upper layer and the lower layer, one or two or more of a majority of a flat area of a front foot portion, a majority of a flat area of a middle foot portion, and a majority of a flat area of a rear foot portion includes a layer of a second foamed body having a thermoplastic resin component; and the second foamed body has a greater specific gravity than the first foamed body, and is formed by a low-resilience material having a low speed of recovering to its original shape after being deformed.

An article of footwear includes a sole incorporating a plurality of apertures extending from an upper surface. The article of footwear further includes a strobel that may be placed along the auxetic structure of the sole. The strobel may restrict the flexure of the sole in particular locations to varying degrees.

Beads may be stitched to a substrate layer and then fused to form structures including foam midsoles, foam pads, and other foam structures. Beads may be embroidered to multiple substrate layers and then folded or stacked together to form a preform used in a mold to form a midsole.

The invention pertains to the footwear sector, principally the children's footwear sector, and relates to physiological footwear with dynamic configuration of microparticles used in a chamber between the insole and the sole. The sole has a counter and an irregular arrangement that simulates natural ground.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.

A spring for a spring shoe, the spring including a conical disk, the conical disk having a flexible flange around the perimeter of the conical disk. A spring comprising a conical disk and a ring spring around the conical disk, the ring spring being movable up and down relative to the conical disk to adjust the spring force of the spring. A threaded engagement between the ring spring and the conical disk so that rotation of the conical disk moves the ring spring up or down relative to the conical disk. A damper ring around the perimeter of the conical disk to resist the expansion of the circumference of the conical disk. An eccentric ring or cam to adjust the position of the apex of the conical disk relative to an insole by rotating the eccentric ring or cam. An asymmetric conical disk to adjust the position of the apex of the conical disk by rotating the conical disk. A damper for a spring shoe comprising a flexible container containing a material with little or no propensity to return to its original shape. A spring array for a spring shoe, the springs of the spring array having a reducing force resisting compression over at least a portion of the spring range of travel as the spring compresses, and there being a damper associated with the array to oppose compression of the array towards maximum compression.
