To surpass your personal record, to enjoy a marathon run, and for flawless performance, you need shoes designed to meet your own requirements! Altra has managed to create that shoe, with top technologies and a fit that matches the actual size of your foot. On uphill and downhill sections, the foot tends to be compressed as you run, but with the Footshape Toe Box, the toes are not compressed. As the Altra Ego midsole increases energy return, the Footpod technology hugs the foot, allowing it to maintain its natural movement.
