When compared directly with the leading insoles on the market, it was found that sprinbak insoles offered a 3 times as much resilence than the competitors.

How can it beat the others by so much? Well basically back when springbaks were invented, they made a number of patents, which by law prevent other insole companies & even shoe makers like Nike from copying them and using the same material.

The space age material they use is called butadiene. Butadiene by itself has 15% more resilence than any other material in the world! The best thing is springbaks are tiny. The width is actually smaller than normal insoles and you wont have to get bigger shoes to house them.

Certainly a must for any athlete, (and they're dirt cheap!)
