The Mammut T Advanced GTX is instantly attractive as it is very lightweight at 1456g and has a striking modern design. The boot has a synthetic upper with leather overlays, and this feels quite robust despite its minimal weight. The toe box is very solid at the end but softer toward the laces – so it’s not the ultimate foot protection on rockier ground, but better than an even softer toe box. You get a rubber rand around the toe box that is very substantial for more durable performance. The sole unit has quite wide lugs, so not the best for biting into softer ground, but a reasonable option for general hillwalking. There is more flex in this sole unit than others around its price, which is surprising and nudges the Mammut T Advanced GTX towards easier terrain, except for those who like a more flexible boot even on rocker ground. On the foot it does feel very comfortable straight from the box. It has a reasonably close fit and the ankle, while providing support, is also comfortable. This is a nice boot to wear. For rockier ground I’d prefer something stiffer, but the Mammut T Advanced GTX is great for moorlands, valley and walks on hill paths.

The Mammut T Advanced GTX is a very lightweight boot that’s best suited to the slightly less demanding terrain and on hill paths, rather than rockier mountain routes.
