Train fast and stable in the Altra Impulse.  Designed to tackle your daily training miles with a little speed, this lightweight shoe uses a responsive midsole on a zero-drop platform to help you maintain a more natural footstrike.  StabiliPod technology at key zones of the foot provide mild support from overpronation, and a breathable air mesh upper keeps your feet comfortable over long distances.
