Help & Frequently Asked Questions

Q ... What's the deal about reducing fatigue, I'm a distance runner?
A: One of Springbak's designs is referred to as the return of energy. Its been linked to the comment of "reducing gravity", by biomechanical and research scientists, such as Dr. Michael Yessis, Ph.D. Dr Yessis' most recent publication confirmed that he had conducted research that proved the Springbak insole indeed has a substantial return of energy with reduced fatigue results.

Q... I play basketball, what type of vertical leap improvement may I expect?
A: Most people using the insoles average approximately 2 inches increase in their vertical leap, but a more explosive type individual will get 3 or more.

Q... What sizes are the insoles? Do they fit all shoes?
A: The insoles come in all sizes for adult men and women, They fit in practically (99%) of any type of shoe including hiking boots and everyday work shoes. Simply put the Springbak insole into your shoe (less than 1/16th of an inch thick), then put your regular shoe insole back on top. Since every foot is different like fingerprints, the insole is designed to remove the excess with scissors.

Q... How long do the insoles last?
A: Lifetime of an insole typically lasts 2-3 years. Some people put in new Springbaks' once a year, even though it's not necessary. Some of our pro athletes put in new insoles every month, but newer insoles are virtually identical to older insoles as to performance.

Q... Would the insoles work for my dad who is on his feet all day as a postal worker?
A: Yes indeed, but if he doesn't notice a difference in leg muscle fatigue after a few short days, we would refund his money.

Q... How do they improve strength?
A: In 1996 Mr. Crow started to design Speedsoles. Mr. Crow along with the careful blending of space-age materials give Springbak insoles the perfect platform for one to draw the maximum electrical currents for one's muscles to perform. The better your muscles perform, the better for you to improve muscle strength.

Q... I'm majoring in modern dance at NYU, can these insoles really help me to leap higher?
A: Yes, for the same reason that they help the basketball player. Whether you are a volleyball player, dancer, football player, or high jumper, our research shows that increased muscle strength and the return of energy result in better leaping and jumping.

Q... I'm Suffering from Shin Splints, is it true that speedsoles eliminate them?
A: Yes, Speedsoles have been proven to totally eliminate shin splints and Speedsoles greatly reduce the chances of having other leg injuries or tendinitis.
