Built for the most demanding trail races, the Altra Mont Blanc Carbon x SOAR delivers top-tier performance from summit to finish line. This ultra-lightweight racer features an updated Altra EGO™ PRO midsole with 32% more cushioning and increased stack height for a softer, more responsive ride. A full-length carbon fiber plate enhances propulsion and stride efficiency, while the Vibram® Megagrip outsole offers confidence-inspiring traction on technical terrain.

Developed in collaboration with SOAR, this trail racing system is precision-tuned for speed, protection, and control in extreme conditions. It’s designed to thrive in heat, over long distances, and at high elevation—all while keeping you light on your feet.
