Mammut - MTR 201 Dyneema

Mammut broke into trail running in the most innovative way. The MTR 201 Dyneema, Mammut's flagship trail running shoe, has been created for those runners who want protection, support and traction on the most impervious terrains. We decided to test the real capability of these shoes on the trails.

Technical Description

The upper, built in a “Single Shell”, seamless construction to reduce potential weak points, is made of Dyneema®, one of the strongest and lightest synthetic fibers on the market: super light and about 60% stronger than carbon fiber and 15 times more robust than steel! The Dyneema is also very resistant to fiber breakdown caused by extended exposure to UV rays.  
Mammut's patented Base Fit® technology uses free-sliding webbing to transfer the force from the lacing area directly to the sole, at the
same time adapting optimally to the shape of the foot.
A rubber cap protects the toes from impact with rocks, roots and debris.
The Mammut MTR 201 Dyneema feature:
  • Fast lacing system with stow pocket for the laces
  • 360 Heel Support: a 360-degree support around the heel area
  • Rolling Concept® technology: curved ribbing integrated into the wedge to help secure the foot‘s natural rolling motion and ergonomic support/damping
  • Sonar Technology design of the sole: concentric rows of cleats designed for maximum transmission of braking and thrusting forces
Weight: 597 g per pair (size 8.5 UK)

Our Test

We tested the Dyneema for 4 months for hiking and trail running.
We tested them on different terrains (rock, sand, grass, gravel), but exclusively in dry weather conditions.

First Impressions
From the very first time you wear these shoes your thought is: “Wow, they are incredibly comfortable!”. And the first impression has always been supported during all the activities we did with them. The sensation you have is that of a shoe that is perfectly adapting to the shape of the foot. You also immediately notice the great damping capabilities and a kind of bulky sole that is thicker and wider than that of the typical running shoes.

Weighting around 600 g per pair, they are definitely not the lightest trail running shoes available on the market, but they can be considered very light hiking shoes. The sole is quite bulky, with a thick and wide profile.

Overall very comfortable, especially thanks to the quite thick, very soft, and very flexible sole, which perfectly absorbs every impact on every surface. Also the fast lacing system provides tailored and comfortable support to the foot and locks it securely in place.

They have good grip on almost every surface, partly thanks to the fact that the very soft rubber of the sole is free to flex and wrap around bumpy surfaces, always copying the shape of the ground. However, the pronounced cleats, which are also very soft, may tend sometimes to compromise a bit the grip and sensitivity on firmer grounds or slabs of rock.
The sole has a thick and wide profile with a very "aggressive" design featuring concentric rows of cleats (dubbed Sonar Technology design). The pronounced edges of the sole enhance lateral stability during steep traverses and the shape of the cleats ensures a secure grip on different surfaces both up and downhill. 

To absorb lateral rolling tendencies (pronation and supination), the shoes provide the foot with a 360-degree support around the heel area ("360 Heel Support") together with sole cushioning, with a special rubber mix, designed to accommodate running movements ("Rolling Concept®"). The Rolling Concept technology forms the midsole and heel into a shape that promotes smooth heel-to-toe transition and reduces foot and ankle fatigue. This gives the sole medium torsional strength, intended to influence the foot's natural rolling behavior as little as possible while, at the same time, providing optimal support. 

Flexibility & Responsiveness
The whole structure of the shoe is extremely flexible, thanks to the soft rubber mix of the sole and the light and flexible upper. The sole is also highly damping in the impact phase and sufficiently responsive in the thrust phase.

The upper is flexible and made to last: the Dyneema is difficult to be
damaged. The rubber used for the sole and the cleats is very soft and slowly tends to wear out and become less responsive with the use. Fortunately this tendency is not very rapid.

Great for long or fast trail running and hiking on dry terrains (not rain). They can also be used on paved roads or for training although the quite bulky sole and the soft cleats reduce a bit sensitivity and precision.

The upper, made of Dyneema, forms a mesh that is quite breathable letting the feet dry easily. We tested the shoes in high temperature conditions and we clearly appreciated how the upper always allowed heat and excess moisture to move away from the feet. Here, obviously also wearing the "right socks" makes a big difference.

Our Verdict

Pretty kick-ass shoes overall, the Mammut MTR 201 Dyneema are comfortable and highly damping trail running shoes, that work really well both for very long hikes, when greater comfort is required, and for fast running on the trails, when performances and durability are more important.
