What Our Gearhead(R) Experts Are Saying: "This is my go-to when I want to move fast on rocky trails. The EGO PRO foam gives me the bounce, and the Vibram Litebase keeps it light without sacrificing grip. Plus, the roomy toe box and zero drop feel super natural on long days." When the trail turns technical and speed is the name of the game, the Mont Blanc Speed Trail Running Shoe is ready to respond. Built for efficiency and comfort on long runs, this shoe uses dual-density Altra EGO(TM) foams to keep our stride lively-EGO(TM) MAX on the outer rim for plush support, and EGO(TM) PRO in the core for energetic propulsion. Traction and weight savings come together with a Vibram(R) Litebase outsole and Megagrip compound, giving us the grip we need on loose, rocky, or wet trails without weighing us down. The zero-drop platform and roomy toe box allow natural movement, while the secure midfoot and stone guard keep us locked in and protected no matter the terrain.
