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.

DURA-Stryk™ - Dura-Stryk is AViA's high abrasion carbon rubber coupound which is placed in high wear areas to increase outsole durability.

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.
