Light, agile, precise and extremely comfortable. CRODA DFS GTX is a mountaineering shoe ideal for challenging climbing and trekking in a mixed environment with rock and ice. The Kevlar upper, combined with the Spider Frame over-injection, guarantees resistance to impact and abrasion and excellent freedom of movement. The Vibram Croda Litebase sole offers stability, grip and precision, even in the most technical situations, allowing the use of traditional or semi-automatic crampons. It adopts the AKU Elica Natural Stride System to promote biodynamic efficiency. The exclusive AKU Dual Fit System (DFS) technology allows you to vary the fit in walking & climbing mode by simply acting on the two different lacing systems, protected by an elastic cover that prevents snow and debris from entering the upper.
