The Mammut Alnasca Knit III are superlight approach shoes with a comfortable and supportive construction. Weighting just 380g thanks to the lightweight knitted mesh uppers they will not weight you down clipped to the back of your harness or in your pack once you move onto technical terrain. Their amazing comfort is provided by an internal stretch mesh lining and 360 Heel Support which is a TPU insert which completely envelops your heel.

The upper is made from a 3D knitted mesh for breathability with a Base Fit sliding webbing which transfers power from the laces to the sole for a snug hold, which improves performance on difficult terrain. The soles are Vibram Megagrip rubber which performs well on wet and dry rock.
