The Altra Women's Mont Blanc Carbon Trail Running Shoes are built to bring race day speed to rugged terrain. Designed with a full length Carbitex(TM) Monoflex carbon plate, this trail weapon delivers powerful propulsion and added underfoot protection for technical climbs and fast descents. A rim and core midsole construction pairs responsive Altra EGO(TM) PRO with cushioned Altra EGO(TM) MAX to balance comfort and performance on long miles. The lightweight upper enhances breathability while maintaining a secure midfoot lockdown for confident movement across uneven ground. Finished with a grippy Vibram Megagrip outsole and zero drop platform, this shoe lets runners move naturally while pushing the pace on everything from ultras to aggressive trail efforts.
