Technology that provides the rebound needed for better, faster impulse, resulting in a more effective and energetic stride.

A system of flex lines, ergonomically placed in the sole to offer better transition between the heel and toe in every step. In the heel, only the sole can flex, which provides a better fit and a more flexible and natural stride.
