Fillauer offers the Emotis designed Wave Comfort Foot System for the low- to moderate-activity amputee. Tri-spring design elements provide seamless transition and stable progression from heel strike to toe off. Coupled springs react in a compliant manner that promotes a supple feel while maintaining the dynamic response expected in carbon composite feet. The 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. Smooth heel rocker action and stable forefoot dynamics enhance comfort.
