Altra Men's Mont Blanc Speed
See our entire range from Altra here!
The Altra Mont Blanc Speed is a fast and responsive men's trail shoe designed for technical trail running, tempo runs and long days on the trails. The shoe combines two midsole materials with a protective StoneGuard™ plate and a grippy Vibram® Megagrip outsole.
Unlike the Mont Blanc Carbon, the Speed model does not have a carbon fiber plate. Instead, a more flexible TPU plate is used, which provides protection against sharp rocks and uneven surfaces.
The midsole features a lightweight Altra EGO™ PRO core surrounded by an Altra EGO™ MAX frame. The combination delivers responsiveness when the pace picks up, while maintaining the cushioning and durability needed for longer runs.
With a stack height of 29 mm, the Mont Blanc Speed is classified as a high-cushioning shoe.
Between the midsole materials is a TPU-based StoneGuard™ plate. It protects the foot from impact from rocks, roots and other irregularities without giving the same stiff feel as a carbon fiber plate.
This makes the Mont Blanc Speed an option for runners who want a fast and protective trail shoe with greater flexibility than the Mont Blanc Carbon.
The outsole uses Vibram® Megagrip, developed for grip on a variety of surfaces. The Litebase construction reduces the amount of rubber in the sole base, contributing to a lower weight without removing the outsole's grip pattern.
The outsole is suitable for technical trails, mountain terrain and surfaces where you alternate between dry and wet areas.

The ultra-lightweight upper is designed to provide ventilation and keep the shoe's overall weight down. A reverse-stitched construction around the tongue and heel collar reduces the amount of material and contributes to a softer feel around the foot.
The fit is adapted for running in technical terrain, where the foot needs to be held in place while the toes have room to move.
The Mont Blanc Speed uses Altra's Standard FootShape™ Fit, which allows for natural toe movement while providing a snug fit across the midfoot.
The Standard FootShape™ is not Altra's widest last. Runners accustomed to the Original FootShape™ may find the Mont Blanc Speed to be more snug across the midfoot and forefoot.
Both models feature 0mm drop, 29mm stack height, EGO™ PRO/EGO™ MAX midsole and Vibram® Megagrip with Litebase. The key difference is in the underfoot plate.
Mont Blanc Speed: More flexible StoneGuard™ TPU plate for protection and a more responsive step.
Mont Blanc Carbon: Full-length carbon fiber plate for a stiffer, more race-oriented feel.
The Speed model is mainly suitable for fast training and long trail runs, while the Carbon model is more clearly aimed at competition and runners who prefer a stiffer shoe.
The shoe is suitable for those looking for a well-cushioned but fast trail shoe for:
Technical trail running
Quick workouts
Long runs
Mountain running
Trail and ultra races
Varying surface with rocks and roots
The Mont Blanc Speed has a 0mm drop, which means that the heel and forefoot are at the same height. If you usually run in shoes with a higher drop, you should increase your use gradually, as the load on your calves, Achilles tendons and feet may change.
Feel free to start with shorter sessions and alternate with your previous running shoes during the transition period.
Measure both feet from heel to longest toe, starting with the longer foot. Altra recommends adding approximately 0.5 cm to the foot measurement before comparing it to the size chart.
