First Claim
1. An article of footwear having an upper and a sole structure, the upper comprising:
- an exterior layer forming at least a portion of an exterior of the upper, the exterior layer including a plurality of incisions that extend through the exterior layer; and
an interior layer located adjacent at least a portion of an inner surface of the exterior layer, the interior layer being exposed through at least a portion of the incisions,wherein a first portion of the incisions are oriented to extend in a direction substantially parallel to a longitudinal axis of the footwear, and a second portion of the incisions are oriented to extend in a direction substantially perpendicular to the longitudinal axis, the second portion of the incisions being positioned adjacent a medial side of the footwear and in a forefoot region of the footwear.

Abstract
An article of footwear is disclosed that includes at least one of a stretchable upper and an articulated sole structure. The upper may include an exterior layer and an interior layer. The exterior layer forms at least a portion of an exterior of the upper, and the exterior layer includes a plurality of incisions that extend through the exterior layer. The interior layer is located adjacent an inner surface of the exterior layer, and the interior layer is exposed through the incisions. The sole structure may include a connecting portion and a plurality of discrete sole elements. The connecting portion is positioned adjacent the upper and may extend along a longitudinal length of the upper. The sole elements extend from the connecting portion, and the sole elements are separated by a plurality of sipes that extend upward into the sole structure.
