Spira® is an advanced footwear brand premised upon a patented and patent pending footwear technology called WaveSpring® Technology. The WaveSpring® is a stable and lightweight spring that is placed in the heel and forefoot of our shoes. Each spring is calibrated based upon the size of the shoe and helps protect against fatigue, stress, shock and impact forces.

Features include:
  • A “mechanical” cushioning system can help you do more, go farther, go harder, with less stress on your feet and joints.
  • The WaveSpring® reduces peak impact forces throughout the gait cycle by 20%.
  • The WaveSpring® is mechanical and works through deflection and opposed to compression.
