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.

Ecto Cantilever System(pp) - The ECS heel is a completely new mechanically advanced technology designed to reduce the shock felt upon impact, and return the energy into the next step. Two molded plastic plates in the heel, separated by a dense material, provide the cushioning and energy return. The top plate acts as a cradle that keeps the heel centered for maximum cushioning, while the concave design in the bottom plate absorbs the impact and as the plates return to their original shape, energy is returned to the step.

DURA-RYD™ - A blown mixture of EVA and PU, Dura-RYD™ is placed in the forefoot and heel strike areas providing superior cushioning.
