Ultra flexible and super lightweight, the Altra Women's Torin 2. 0 Running Shoe is designed to keep your feet well cushioned and your technique flawless. Whether you're training in the gym or sweating through an Ultramarathon, this neutral running shoe has a FootShape Toe Box that allows your toes to spread out naturally, enhancing your stability and speed, while the fully cushioned Zero Drop platform naturally aligns your body posture and promotes low impact technique. The dual layer EVA InnerFlex midsole utilizes grid like grooves to maximize flexibility and reduce weight as the A Bound layer provides superior cushioning for your feet to bounce happily along. The FootPod outsole maps the bones and tendons of your foot, allowing the shoe to flex with your movements, as opposed to forcing your foot to flex with the rigid structures of your shoe.
