This evolution includes the addition of an AltraEGO™ midsole, bringing an extra level of response to every step you take while conquering all types of terrain, with the MaxTrac™ outsole. The updated StoneGuard™ offers more coverage while using less substance, and the laser-cut drainage holes allow you to get drenched with added drainage.
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 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.
Our original Altra EGO™ foam is designed to provide added energy return and a responsive, yet soft, comfortable feel.
Our grippy MaxTrac™ outsole provides the perfect combination of grip, traction, and durability on all types of terrain.
These canted lugs on the outsole are strategically placed beneath the metatarsals to provide added traction underfoot.
This hook-and-loop tab allows our strapless gaiter to easily attach to the shoe, adding protection against rocks and debris.
