NIKE: "W. A. R. P. Tech AKA Windlass Activation Resupination Pod Technology
The name is extremely confusing to any one including myself but it's just a fancy way of saying the softer material under the ball of the foot increases the foots natural Resupination to propel itself foward. They call this the "Windlass Effect" (where the foot converts into a rigid lever during toe off). The pod of softer materials is positioned right under the ball of the foot where the metatarsal joints naturally flex."
