A variable friction shoe includes a midsole and an outsole. The outsole includes at least a first high-friction surface and at least a first low-friction surface, wherein the first low-friction surface remains prominent if vertical ground reaction forces (GRFs) are low and wherein the high-friction surface is prominent in response to increasing GRFs.

An article of footwear includes a chassis, and the chassis includes a body having a toe end, a heel end, a top surface, and a bottom surface. A distance from the top surface to the bottom surface is a thickness of the chassis, and the body defines a perimeter of the chassis. The chassis may include an aperture within the perimeter of the chassis that extends through the thickness of the chassis. A center region of the body between the toe end and the heel end may include a cored region having a cavity defined in the top surface of the body and at least one vertical support within the cavity. In some aspects, the body includes a non-uniform thickness.

An ankle foot orthopaedic apparatus (10) includes a sole (66), a control part (18), and a connection arrangement (16) for connecting the sole (66) to the control part (18) for controlling or guiding the orientation of the sole (66) in use. The sole (66) includes a sole connector part (20), which comprises part of the connection arrangement (16). The control part (18) includes a control part connector part (22), which comprises part of the connection arrangement (16). The connection arrangement (16) permits movement of the apparatus (10) between a connected condition, in which the sole (66) is connected to the control part (18), and a disconnected condition, in which the sole (66) is disconnected from the control part (18).

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.

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.
