Maximize your comfort and speed with The One2™ from Altra. Built into the midsole, InnerFlex™ features grid-like flex grooves that allow your foot to flex where it needs to for more freedom and propulsion. The FootPod™ outsole provides flex grooves on the outside that allow your feet to utilize their natural stability zones. Female-specific design accommodates the narrower heel, higher instep and longer arch of a woman's foot. And, like every Altra shoe, the One Squared features our innovative cushioned Zero Drop platform to encourage proper, low-impact running technique. And thanks to the FootShape™ toe box, your next marathon could be free of black toe nails, blisters, and foot discomfort. Take your running performance to a whole new level with the One².
