People can usually feel the difference right away thanks to Spira’s unique and patented WaveSpring technology.
The “mechanical” cushioning system can help you do more, go farther, go harder, with less stress on your feet and joints. Think of our technology as “little shock absorbers” for your body. Whether you stand, walk, jog, run, exercise at the gym or take pleasure in leisure activities, Spira can help make all more comfortable and enjoyable.
Not all springs are created equal
Coil Spring versus WaveSpring
Of course, the idea of a spring in a shoe is not new. Wile E. Coyote had to learn the hard way because traditional coil springs do have their limitations. But our patented “crest to crest” WaveSpring design is different; it has many little “leaf” springs combined into one larger spring, all working together in perfect harmony to create a powerful cushioning and energizing experience. This is serious equipment for your feet!
Coil springs are laterally unstable. Shoes require a stable platform to function properly. However, the WaveSpring with its unique design has significantly less lateral movement which makes it more stable.
Coil springs have to be tall to provide significant deflection and energy return in a small space. Placing coil springs in a traditional shoe midsole is a challenge because space is limited. The WaveSpring is compact and gives optimum deflection and energy return in a small space.
Take your races, runs and workouts to a new level with our popular high performance and lightweight neutral shoe with superior cushioning, shock absorption and energy return. Designed with low profile, lightweight stainless steel WaveSprings in the forefoot and heel, spring deflection and cushioning properties are not compromised. This style is popular with elite athletes, recreational runners and weekend warriors alike.

What makes the Spira brand unique? The patented WaveSpring technology can only be found in Spira shoes.
Why do I need Spira’s WaveSpring technology??
The WaveSpring not only cushions with every step, but returns almost the same amount of energy. Up to 96% of the energy is returned to the wearer. This “recycled” energy allows you to participate in your activities with far less stress on the joints, ligaments and the entire body than traditional footwear.
The WaveSpring reduces peak impact forces throughout the gait cycle by 20%. It is during these peaks that injuries usually occur. With the reduction of peak force, injuries can be reduced. Many elite athletes, marathoners and fitness enthusiasts report that they can race, train and work out at a more intense level. Recovery time between activities is often reduced.
The WaveSpring is mechanical and works through deflection and opposed to compression. This helps to shoe keep the “new shoe” cushioned feel throughout the normal life of the shoe.
The WaveSpring is very tunable. There is a different sized spring dependent upon the size of the shoe, and a different spring configuration dependent upon the proposed activity. It is truly customized to the wearer.
How do I clean the shoes?
Spira shoes should be washed by hand using laundry detergent (sparingly) or shoe cleaner. Avoid submerging the sole of the shoe in water. We do not recommended washing shoes in a washing machine or placing them in a dryer.
Can I wear my orthotic insert in a Spira shoe?
Yes, you can remove the shoe insert and replace it with an orthotic.
Why are there so many different spring configurations?
The WaveSpring configurations (one, two or three springs) are tuned for particular activities. For example, The Spira Classic models have two large springs for a more bouncy feel and cushioning needed for walking, medical rehabilitation, and/or standing all day.
The WaveWalker and WaveWalker DX3 have a “firmer” feel and a larger forefoot area to accommodate a wider foot, yet the heel remains narrow to reduce slippage. Based on personal preferences, you can choose either the 1 or 3 spring option.
The Odyssey, Genesis X and the Stinger XLT offer three WaveSprings to provide more forefoot flexibility for various athletic and dance fitness activities.
Can I wear Spira shoes for competitions?
Runners competing in Spira shoes have won hundreds of major marathons and road races worldwide.
