Great comfort and support with very little weight, for alpine trekking.

The Mammut® Monolith GTX is a very light, very comfortable crampon-compatible alpine and trekking boot.

Constructed using abrasion-resistant velour leather and 'Dropstop' textile, the Monolith GTX is both flexible and supportive, thanks to Mammut's Motion Control technology - the cushioning Hybrid Shell providing good support exactly where it’s needed.

Mammut's Base Fit technology uses free-sliding bands to transfer the force of the lacing to the sole, adapting to the anatomy of the foot and boosting the pressure on the big toe for precision footwork.

Rounding out this full-featured boot are a fully waterproof, highly breathable GORE-TEX® Performance Comfort Footwear membrane, a high-grip Vibram® Teton sole and a fully adjustable 3-zone lacing system.

Fantastic, 15 February 2015
By Guevargas (Colorado, USA)
These boots do it all and are extremely reliable in any type of conditions. Have taken them up the CMD Arête, An Teallach, Suilven, Longs Peak, Wheeler Peak, Uncompahgre, Santa Fe Baldy, and Cabezon Peak to name a few. I've put these boots through the ringer and they have never let me down. They work extremely well for scrambling too.

Excellent, 04 October 2014
By fjellsman (Penrith)
Excellent service from Penrith as ever, Nigel made me choose a bigger boot than I have been used to wearing, but now owned for nearly a year and no complaints at all. They been run out in almost all conditions on average twice a week. A very fine boot capable of taking everything thrown at them. Good foot bed, nice feel, enough 'give' to make all day walking OK. Tremendous lacing system that gives great control.Warm but not sweaty and dry in the wet. I have broad feet and can suffer on the long descents….no such problems with these. Takes a crampon with no difficulty. Good value

Mammut Monolith GTX Boots, 01 October 2014
By Gabe (St Albans)
First of all these boots are very light and comfortable.Used for one week in the Alps,mixed terrain,long distances,glacier and moderate ice climbing.Worked brilliantly!!!!
Stiff enough for crampon use but worked very well last weekend climbing Hellvellyn via striding edge.Have to say amazing for scrambling!
If you want only one boots do everything,look no further.

Mountaineering Boots, 22 July 2014
By Neil (Wirral)
Bought for winter mountaineering, very pleased and highly recommend these boots to anyone who's looking for a winter mountaineering boot.

I will add that these boots can feel a little flexible for a B2 boot but that will be due to me with size 12's so if buying larger sizes may be something to consider.

Rubber rand splitting, 02 June 2014
By copey (Lincoln)
Bought these boots for the winter season, I have worn them twice once in Scotland and once in the lakes and have noticed the rubber rand is splitting all over the toe and heel on one boot, however these boots do fit like slippers and are light.
