Cantilever® - Centers the heel over a concave sole. The concave sole acts like a trampoline to soften impact, stabilize the heel and provide increased energy return.

FOM™ - Mimics the way your foot compresses shock and is located in key impact areas, much the same as the fat pads in your foot. Made of extremely soft, yet dense material, fom™ conforms to your foot on impact for excellent cushioning and comfort, then bounces back to its original shape after each impact.

ART REBOUND TECHNOLOGY™ (ART) - The ART™ System is a cushioning and shock absorption system for the neutral runner. It features a responsive injected plate that is positioned under the heel, which works in conjunction with the Cantilever®. Upon heel strike the ART™ plate gives like a trampoline despersing shock, then springs back to it's original shape, returning energy to the stride at liftoff.
