Dual Cantilever System® - Maximizes stability and cushioning with pressurized dual reverse Cantliever® units. The top side cradles your heel, keeping it centered directly under the body while using heel fat to cushion the stride. The bottom Cantilever® acts like a trampoline to soften impact, stabilize your 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.

Anatomical Cradle® - Improves both motion control and shock absorption by mimicking the bottom of your heel in your midsole. An anatomically correct last, literally cradles your heel, holding it right where the foot's own natural padding and the shoe's cushioning will absorb the most impact. This means less shock on the rest of the body. The cradle also centers and holds the heel firmly in place to reduce twisting on both ankles and knees.
