Wave of Comfort - Wave Comfort 3 Foot System

Wave Comfort 3

The Wave Comfort 3 brings an exceptional level of comfort to the low to 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 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.
