The Wave Comfort Foot System brings an exceptional level of comfort to the low and moderate activity user. The unique tri-spring design elements work in concert to provide seamless transition and stable progression from heel-strike to toe-off. The coupled springs react in a compliant manner that promotes a supple feel while maintaining the dynamic response expected in carbon composite feet. The novel wave spring and variable durometer heel bumpers enhance stability at heel strike through shock absorption and plantar-flexion as the wave spring flexes and extends. The smooth action of the heel rocker combined with the stable dynamics of the forefoot insure a “Wave of Comfort” from heel to toe.
