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.

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.

ART Elite II™ - combines AVIA's Anatomical Rebound Technology with an ultra lightweight bottom, and sleek supportive midfoot shank. Assists with overall flexibility and energy return with each heel strike.
