“Wow!” That’s what many say who try on a pair of Spira shoes for the first time. 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.
The Spira Scorpius Stability Runner provides support for the moderate to extreme pronator by incorporating a wide heel platform and an extended high density medial post. Stability and cushioning are combined without compromising comfort. Newly designed WaveSprings in the forefoot and heel provides superior cushioning a resilient at half the weight. A rigid TPU shank offers midfoot support and stability. The Dynamic Fit System adjusts to the changing dynamics of the instep during the gait cycle. The foot-bed may be removed to accommodate orthotics.
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.
