Spira

For years, athletic and comfort shoe engineers have been trying to create a buffer between the foot and the road. Spira engineers have developed a solution – an energy return system that works with the ground by sending expended energy back to the wearer. It is called WaveSpring™ technology and it is found inside every pair of Spira athletic walking and running shoes.

WaveSpring™ technology returns energy with every step. Energy that is otherwise lost to the ground is recycled to the wearer, providing a remarkable combination of cushioning and energy return, making it easier to stand, walk, run and compete.
