The Mont Blanc Speed is the perfect shoe for trail distances up to and including the marathon, but also for long runs at a high pace. The ultimate trail shoe for races!
Midsole
The midsole is made up of two foams. Directly under the foot, you will find a layer of Altra EGO™ PRO, a super lightweight and responsive foam. The bottom layer of the midsole consists of Altra EGO™ MAX. This luxurious, lightweight foam is specially developed to make running as comfortable as possible. It is relatively soft and provides good energy return. With its Standard FootShape™ fit, the Mont Blanc Speed offers ample room for the foot to move naturally. The Balanced Cushioning™ platform positions your heel and forefoot equally spaced from the ground, promoting better alignment, shape, and a low-impact landing.
Upperwork
A monomesh upper provides flexibility and a breathable upper on the Mont Blanc Speed. Monomesh is made of a thin material, but this does not make the upper any less sturdy.
Outsole
With the Vibram® LiteBase Megagrip outsole, you get the best of both worlds. It is made from a rubber compound that is exceptionally durable and offers unparalleled grip on both dry and wet surfaces. Furthermore, Litebase technology ensures that grip, traction, and durability are maintained, while the sole thickness is reduced by 50% and the total weight by 30%. Get ready for the trails: order the Altra Mont Blanc Speed now and start your next trail adventure soon!
