Details Three-season mountain boot for long, fast days over rock and ice Waterproof, breathable HDry with a strong synthetic upper Full rubber rand offers protection from rocks and terrain Multi-density midsole assures stability, support, and cush Vibram rubber sole with Pentax Precision XT tread for mountain-worthy traction. Springtime is still host to icy sections until they melt from summer's heat, and then you have rocky terrain to climb until autumn covers those steep hills with snow. Instead of having a pair of boots for each season, go with a heavyweight, super warm boot for winter, and leave the rest of the seasons to the Scarpa Women's Charmoz Mountaineering Boot. Scarpa made this boot light and versatile for technical alpine objectives in fall, spring, and summer. Its waterproof, breathable HDry membrane lets you traverse glaciers, boot up snowy steeps, or just enjoy a little springtime rain in the alpine without worrying whether your socks will come out a watery mess or not. The Vibram rubber sole has a tread designed specifically for mountaineering, and it accepts semi-automatic crampons I tried these on but never used them. Missed the window to return them. My loss your gain. CASH ONLY*
