The Altra Via Olympus has taken the beloved Olympus trail shoe and created an all-new, high-cushion road trainer. The signature FootShape™ technology allows for a more natural fit to your footshape, letting your toes spread in the extra space. The 33mm of Altra EGO™ MAX midsole gives you maximum cushion for those long miles on the road, while still feeling lightweight. It also utilizes a rocker shape that helps encourage a propulsive ride and more efficient toe-off with each stride.
