All athletes run fastest on a rubberized track. The spring effect of the track means shorter foot plant times, longer stride lengths and thus, faster times. Springbak's work on the same principal, Springbak's are manufactured from a far more springy (resilient) material than a rubberized track.
Because of Springbak's recoil effect, (they return energy when your weight compresses the material) they do not bottom out. Walking, running or standing, you will feel as if you are riding on Springkak's. The effect is especially notable on hard surfaces like concrete or ashphalt. In addition, they great preventor of the effects of shin splints. They also greatly complement orthotics, very thin and go under your shoes existing insole or orthotic.
US Patents issued for the following claims: Faster Running Speed - Increased Body Strength - Increased Stability - Increased Flexibility - Increased Vertical Jump - Quicker Reaction Times
So, what's it made of? Springbak Springsoles are made from the two most resilient materials in the World. Budadiene rubber and natural rubber along with other resilient materials. Springbak Springsoles are really a 'Patented Platform' made into the shape of an insole from highly resilient materials. Remember, Springbak's go under your shoes exising insoles or orthotics.
Made in the U.S.A. 30-Day Money Back Guarantee
Run Faster, Jump Higher Guaranteed. Better your 40 yard dash times immediately. Springbak Springsoles are made from the first footwear material to be issued U.S. patents in the category of "Performance Enhancing Shoe Components". Springbak Springsoles feature a "Recoil Process" that returns 80% energy to the wearer by compressing then springing back to original shape. This process also increases your speed, quickness, and strength while reducing fatigue, shortening recovery time and totally eliminating shin splints forever.
