These AKU Viaz DFS GTX boots are great for mountaineering and hiking. To use them, just put your feet in and adjust the laces to get a comfortable fit. The Dual Fit System lets you change the fit for walking or climbing. When you're on the move, the Dynamic Fit technology will adjust the heel tension as you step. For safety, always make sure the crampons are properly attached if you're using them on icy or slippery surfaces. After each use, clean the boots with a soft brush and mild soap to remove dirt and debris. Let them dry naturally away from direct heat. Store them in a cool, dry place. If the laces get worn out, replace them to keep the boots in good shape.
