Product Details

The Mammut Men's Taiss Light Mid GTX Boots are built for climbers and mountaineers who want a lighter boot without giving up the support and security needed in alpine terrain. At 550 g, this is Mammut’s lightest crampon-compatible mountaineering boot, designed to balance lightness, durability, and performance for everything from exposed approaches to glacier travel and steep ground.

What stands out here is how the design keeps the boot precise and capable without feeling overbuilt. Vibram Litebase trims weight from the sole while maintaining the grip needed on rock, ice, and snow, and the semi-automatic crampon compatibility gives it real mountaineering range. Details like the asymmetric lacing, mono-tongue construction, and integrated neoprene cuff gaiter make sense once you’re moving through mixed conditions and don’t want your footwear slowing you down.
