The Impact Guidance System (I.G.S.) is an ASICS design philosophy. It aims to make shoe components from rear to midfoot and forefoot to work together effectively to allow the body to perform in a natural manner. ASICS designers strive to compliment, not correct, how the legs and feet move.
Tough material placed in critical areas of heavy contact on the shoe for exceptional durability.
