To surpass your personal record, to enjoy a marathon run, and for impeccable 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 uphills and downhills, the foot tends to be compressed as you run, but with the Footshape Toe Box section, the toes are not compressed. As the Altra Ego midsole increases energy performance, the Footpod technology embraces the foot, allowing it to continue its natural movement.
