Mammut Teton GTX (2012)

Mammut first brought the Teton GTX out with the promise that it would give the wearer the grip and precision of a mountain goat. And looking underfoot it’s obvious immediately that this boot has been designed with rocky terrain in mind. The outsole offers a good level of stiffness, particularly at the front to help with edging on short, scrambly sections. Your toe is also protected with a reinforced box and a rubber rand. At the back your heel is supported with extra rubber too. The lugs, though not as aggressive as others, are widely spaced to help stop the build-up of debris, but they would last longer if there were deeper. A heel breast helps with descents, giving added grip. Inside there’s a Gore-Tex lining to help keep feet dry and a good amount of cushioning, which is key for comfort on longer walks. The fit is a little wide so better for broader feet. I did feel pressure from the eyelets at the mid foot but then my feet do have a high intstep – so it’s advisable to try these on to ensure they fit your foot. The only real downside is the Mammut Teton GTX’s weight (1305g per pair), making these the second heaviest boots in our test.

Weight 1305g (pair, size 6)
Upper materials velours leather and textile
Waterproof lining Gore-Tex Performance Comfort
Sole unit Vibram Tec Hiking sole with PU
Women’s sizes 3.5-9
Men’s sizes 6.5-12



The Mammut Teton GTX is a well-featured boot that’s good on rock and muddy terrain – but the heavier weight may put some people off.
