Altra Men's Medium Arch Running Shoes

Relative newcomer Altra broke through a saturated market by introducing three radical design changes to traditional running shoes: 1) a Footshape™ toe box to accommodate the natural shape of the foot; 2) Fit4Her™ technology tailored to the unique anatomy of the female foot; and 3) a ZeroDrop™ platform that keeps a runner's heel and toes even with the ground.
