Featuring WaveSpring® Technology
WaveSpring® returns energy with every step.
Unlike traditional shoe midsoles made primarily of foams, rubber compounds, or polymers, WaveSpring® technology stores and disburses energy with every step. Testing performed at Michigan State University in 2001 reported that 87% – 96% of the energy is returned from the WaveSpring®. This is the highest energy return score for any midsole material ever tested.** As a result, our footwear not only cushions, but returns energy. In a very real sense, the WaveSpring enables you to recycle your own energy!
Unlike rubbers and polymers, the springs have an almost infinite fatigue life. The shoe will fall apart before the spring performance degrades.
