A shoe may include an upper portion constructed from a continuous textile (e.g., a knit textile) that includes an elastic region and a structural region. The elastic region may be positioned about a perimeter of an opening into a cavity configured to receive a wearer's foot, and the elastic region may be configured to secure the shoe to a wearer's foot. The elastic region may have a first elasticity that is greater than a second elasticity of the structural region. In an unworn configuration, the elastic region may cause a tread surface of a sole of the shoe to have a continuous curvature. In a worn configuration, substantially all of an intermediate section of the tread surface may contact a surface on which the shoe is placed. The elastic region may improve the performance of the shoe, including the comfort and durability.

Provided are, among other things, systems, methods and techniques for making a shoe outsole and to shoe outsoles made using such techniques. In one such technique, a sheet of composite material is produced by extruding a base material together with a sheet of fabric material. The sheet of composite material is then cut into an outsole component, and a shoe outsole is fabricated using the outsole component.

A sustainable textile yarn composition, method, and exemplary use of the sustainable textile yarn that addresses the need for sustainable and environmentally friendly materials in the textile industry. The invention encompasses a unique combination of recycled coffee grounds, recycled polyethylene terephthalate (PET) plastic, virgin PET, elastomer, and an anaerobic biodegradability acceleration agent to create a textile yarn that is capable of degrading in both aerobic and anaerobic environments.

A shoe having breathable design is provided. The shoe comprises a sole and an upper which is arranged on the sole and has an inner surface. An upright cotton layer is arranged on the inner surface. The upright cotton increases breathability and provides comfort.

A sole (100, 300) for use on an item of footwear (200) wherein the sole (100,300) provides a housing for a growth medium (40) capable of growing and maintaining grass (45). The sole (100, 300) is arranged to be fitted to a lower face of an item of footwear (200), the sole is adapted to retain a growth medium (40) suitable for growing grass (45), so that when fitted to the item of footwear (200), blades of grass project distally from the sole through a mesh (30). The user therefore has the sensation of walking on grass even if not on a grassy surface.
