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—a cushioning and 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 shoes. Whether you are walking, running or on your feet all day, Spira shoes provide exceptional comfort and energy return which gives you the element of advantage.
