Spira Footwear

Spira is a young company that is gaining national attention with its remarkable athletic running and walking shoes. Spira is premised upon a proprietary unique shoe technology called Wave Spring™. Energy that is otherwise lost to the ground is recycled to the wearer, providing a remarkable combination of cushioning and energy return. Unlike traditional shoe midsoles made primarily of foams, rubber compounds, or polymers, Wave Spring™ technology stores and disburses energy with every step Spira makes it easier to stand, walk, run and compete without the stress and fatigue associated with traditional shoe midsole materials. Spira heel and forefoot spring configurations are engineered for specific activities to meet individual needs. Sport Bio mechanics, Inc. tested the Wave Spring™ technology and found it had the highest return of energy of any shoe technology they have ever tested — 87-96%. Traditional midsole materials work through compression and often breakdown quickly. The Wave Spring™ is mechanical. The spring will outlast the shoe.
