Dual layer sole system with auxetic structure

Abstract:

A sole structure including a first layer and a second layer is disclosed. The first layer includes a set of apertures arranged in an auxetic configuration that permits the first layer to exhibit a first auxetic behavior. The second layer includes a set of projections arranged in an auxetic configuration that permits the second layer to exhibit a second auxetic behavior. The first layer and the second layer may be joined together in a manner that allows the first auxetic behavior to occur independently of the second auxetic behavior.
