An article of footwear includes an upper formed of a base layer, a reinforcement layer, and an auxetic structure coupled to the reinforcement layer. The base layer includes an elastic material and is elastically deformable between a resting configuration and a stretched configuration. The base layer is configured to be stretched to a predetermined amount. The inelastic reinforcement layer is coupled to the base layer. The reinforcement layer is configured to delimit the stretch amount of the base layer when the base layer is in the stretched configuration.

Disclosed is a stretchable, three-dimensional tubular structure formed due to processing-induced wrinkles to result in a platform for stretchable interactive electronics. The three-dimensional tubular structure is fabricated simply by releasing a pre-stretched two-dimensional film-substrate precursor, and the resulting wrinkled surface shows a strong directional dependence that drives the tube formation.

A multi-layer bladder construct consisting of a non-stretchable outer covering and a stretchable inner bladder. The outer covering has an inner surface and is made from woven polymer fibers having a warp direction and a weft direction. The inner bladder is made from a bi-axially oriented polymer film. The inner bladder has an outer surface area that is smaller than the inner surface area of the outer covering. Upon inflation, the inner bladder stretches and expands until the outer surface of the inner bladder engages the inner surface of the outer covering, whereby a portion of tensile force loading on the outer covering is shared with the inner bladder. A stretchable flexible film is incorporated into the inner bladder in at least one selected location. The stretchable flexible film has an elastic expansion range which is greater that the elastic expansion range of the remainder of the inner bladder.
