Experience the “WOW” Factor!

“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.

Spira Stinger 2

The Stinger 2 has been a shoe three years in the making. It is an ultra lightweight running/racing shoe with three re-engineered springs. The WaveSpring technology provides a high level of responsiveness and protection against fatigue and stress while combining a level of cushioning and responsiveness that is difficult to achieve for a shoe in this weight category--weighing a mere 7.8 oz*. The foot-bed may be removed to accommodate orthotics. We believe that most anyone can achieve a 15 second per mile personal best from any distance from the 5k to the marathon!

Features

  • Two WaveSprings in the forefoot and one in the heel: provide maximum energy efficiency in conjunction with a high level of cushioning
  • The WaveSprings are low profile with light weight and are made of stainless steel which do not breakdown from the elements
  • Open air mesh vamp provides maximum breathability, comfort and fit
  • Outsole grade EVA with light weight rubber inserts in the heel and forefoot designed to minimize weight
  • Weight: 7.8 ounces for Mens size 9 / 6.5 ounces Womens size 7

Benefits of Spira’s WaveSpring Technology

  • Offers superior cushioning while helping to reduce peak impact forces, stress, fatigue and recovery time between activities
  • Maximum resiliency and superior cushioning
  • Lightweight stainless steel WaveSprings provide a “new shoe” feel for the life of the shoe

Product Reviews for Spira Men's Stinger 2 Running Shoes (Cobalt / Navy / Antifreeze)

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.
