Abstract
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.
