What Our Gearhead® Experts Are Saying:"I wore the Taiss Light Mid GTX Mountaineering Boot on a multi-day alpine traverse and barely noticed them on my feet, which is exactly the point for a boot this light. The carbon fiber midsole gave me solid crampon-compatible support without the usual stiff, heavy feel, and the 2-zone lacing let me dial in fit around my ankle separately from my forefoot."A long alpine traverse demands a boot that disappears underfoot while still holding its own on rock and ice, and the Taiss Light Mid GTX Mountaineering Boot from Taiss does exactly that. At just over a pound per boot, it moves with you across scree fields and up steep snow approaches without the fatigue that heavier mountaineering boots bring on by hour six.The carbon fiber midsole delivers a rigid, crampon-compatible platform while keeping weight to a minimum, and the Vibram XS Trek outsole with Litebase technology grips wet rock and packed snow alike. A GORE-TEX lining keeps moisture out through stream crossings and wet weather, while the elasticated mono tongue and raised rubber rand work together to relieve pressure points where the foot meets the boot, even on long days in technical terrain.
