Rating: rated 5 of 5 stars
Source: bought it new
Price Paid: €279 Cork Ireland


Light, precise Goretex and leather boot for hillwalking, scrambling, and crampon use in easy summer alpine or Scottish winter.


  • Light but supportive
  • Stiff sole with slight flex at toe and good rocker = comfortable for walking and good for scrambling
  • Precise lacing and narrow fit at ankles/heels


  • Stock insole not great
  • Some rubbing due to high ankle cuff — sorted by playing around with lacing tension & pattern

I bought these as replacements for a venerable pair of Meindl Nepal Pros as my "do-everything" boot for hillwalking in Ireland, Scottish winter walks, and moderate snow/ice/mixed climbing. They will take strap-on or hybrid (toe basket and clip heel) crampons.

I was initially considering the newer Meindl Himalaya and tried these on as a alternative, as Mammut have a reputation for a narrow fit at the ankle, which I need. The fit and comfort were noticable, as was the markedly lighter weight compared to my old boots. Despite their stiff sole, the pronounced rocker in the sole gives a very easy, natural stride when walking.

Other than removing the stock insoles and putting in my Black Superfeet, I wore these straight out of the box on what ended up as a 22km hike, which may not have been the best approach to breaking the boots in!

Apart from a little playing around with the lacing en-route to lock down my heels and eliminate an annoying rubbing by the left ankle cuff, I had no issues with comfort on their maiden voyage, albeit the terrain was reasonably gentle (mainly boggy tracks and rough mountain paths). No blisters or hot spots at all, which was great.

The sole had good grip on wet and greasy rock and  the boots felt very nimble when climbing or descending rocky sections.

Looking forward now to giving them an outing on more testing terrain, but the omens are good.

As a fabric and leather hybrid boot I doubt they will last as long as my old Meindls though. They also would not be warm enough for winter alpine or high altitude.

Manufacturer's Description refers to the men's version

This light, crampon-compatible alpine and trekking boot offers an advanced level of comfort. Fashioned from abrasion-resistant velours leather and Dropstop textile, the Monolith GTX is both flexible and benefits from strong lateral support thanks to the Mammut Motion Control technology. The cushioning Hybrid Shell provides support exactly where it’s needed. The patented Mammut Base Fit technology uses free-sliding bands to transfer the force of the lacing to the sole.

The asymmetric lacing adapts to the anatomy of the foot and boosts the pressure on the big toe for precision footwork. Rounding out this full-featured boot are a waterproof GORE-TEX Performance Comfort Footwear membrane, an exclusively developed high-grip vibram Maton sole and a fully adjustable 3 Zone lacing system.

The Monolith GTX is a mountaineer's best friend. Mammut's hybrid design puts hard protective materials in the upper only where they are necessary meaning that you have a flexible boot that can form to your foot for a better fit. The Vibram sole has a nylon and fiberglass wedge for increased stiffness which strikes the perfect balance between walkability and crampon compatability. An insulated GORE-TEX liner keeps you warm and dry no matter what the mountain throws at you.
