Taiss Pro High GTX® Men. The gaiter edition of Mammut’s technical material mountaineering boot range. An extremely lightweight alpine boot that reduces fatigue. The Vibram Litebase reduces the boot's weight whilst retaining the same level of performance thanks to the special texture of the rubber sole. Feet stay warm and dry thanks to Gore-Tex® Duratherm and a natural fit is ensured through the use of Mammut Georganic 3D Technology™. Inspired by our Eiger Extreme Collection, the technical shaft and sole make the Taiss Pro High GTX® Men an ideal winter alpine boot.
