Spira Shoes

For years, athletic and comfort shoe engineers have been trying to create a buffer between the foot and the road. The solution is Spira's WaveSpring™ technology. It sends expended energy back to the wearer, and it's found inside every pair of Spira athletic walking and running shoes.

Spira shoes engineered cushioning system reduces stress and fatigue by returning 87-96% of energy normally lost to the ground. This not only increases performance levels, but also reduces risk of injury.

Currently, USATF rule 143.3 bans shoes giving runners an unfair advantage through the use of springs. This hasn't stopped runners around the world from embracing the health and performance benefits of WaveSpring™ Technology.

Spira will serve as the official performance footwear sponsor of Disney's ™Endurance Series events at Walt Disney World Resort near Orlando, Fla. and Disneyland Resort in Anaheim, Calif.

More on Spira's WaveSpring Technology

WaveSpring™ returns energy with every step.
Ray Frederickson, president of Sports Biomechanics, Inc. compares typical midsole materials found in many athletic shoes to running in sand. While initially perceived as soft and comfortable, these shoes require the wearer to exert greater effort. Muscles must work harder, causing fatigue and increasing risk of injury.

WaveSpring™ is light and compact.
The WaveSpring is laterally stable, lightweight, compact and easily fits into a typical shoe midsole.

WaveSpring™ technology will not break down.
Traditional midsole materials work through compression and often breakdown quickly. WaveSpring is mechanical, so the spring will outlast the shoe. The Spira shoe wearer will have a "new shoe" feel from the first day it is worn to the last.
