Montrail Women's I.C.E. 9 Mountaineering Boot:
Designed for alpine climbing and extended mountaineering in temperatures as cold as -30C, the I.C.E. 9 delivers more insulated warmth than any other Montrail boot. It's also taller and more supportive, making it an exceptional boot for mixed climbs on any of the towering low-angle volcanoes along the Pacific Rim's Ring of Fire. Unlike traditional climbing boots that often use one rubber compound throughout the outsole, the I.C.E. 9 features an exclusive dual-compound Vibram® outsole with a high-durometer Mont compound around the perimeter for superb edging and a soft Super Trek compound in the forefoot for smearing on rock. If you had to own one boot for glaciers, scrambles, vertical ice or anything mixed, the I.C.E. 9 is the easiest choice to warm up to.
