Our signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.
Our original Altra EGO™ foam is designed to provide added energy return and a responsive, yet soft, comfortable feel.
Our Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment, better form, and a low impact landing.
These grid-like grooves in the midsole are designed to provide flexibility and movement.
This outsole technology actually maps the bones and tendons of your foot to encourage natural movement underfoot.
