Abstract:
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.
