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.

Great value, 27 September 2015
By Phil (Leicester)
These boots are good. Excellent support and protection. When scrambling you get great leverage from the toe and can happily jam your feet into cracks to climb without feeling a thing.

They take crampons well (C2) and are definitely sturdy enough for winter mountaineering.

The above said, as another review mentioned, the rubber rand is of poor quality. Mine has started to split and crack in a few places after a few days of (admittedly fairly aggressive) use.

So, if you are looking for a cheap pair of four season boots for occasional use in the winter then these are great. If you want a workhorse winter boot then I'd pay a bit more for something more durable.

FYI, a lot of reviews seem to suggest that these are a good year-round boot if you just want some extra support! To me this is insane! 4 season boots are like walking in clogs on any flat paths or rocky steps! 4 season boots are most suitable for snowy or extremely rocky terrain. They don't have enough cushioning or flex for non-mountainous hiking, so save the money and get 3 season boots if you don't plan on breaking out the crampons and ice axe. Your feet and wallet will thank you.

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.
