The Altra Escalante 2 men's running shoe features the flexible Altra Ego midsole and outsole that has been decoupled for a more natural ride. The addition of the PU insole adds to the comfort of this trainer. The new knit upper has perforations for breathability and delivers a secure comfortable fit. It includes Innerflex in the midsole for more speed and better performance. This zero-drop shoe id built on a level platform with a foot-shaped profile to accommodate for natural foot movements.
