For climbers who demand both accuracy and safety, the 𝐀𝐬𝐨𝐥𝐨 𝐒𝐲𝐦𝐛𝐢𝐨 𝐆𝐕 𝐂𝐨𝐫𝐭𝐞𝐜𝐜𝐢𝐚 𝐛𝐨𝐨𝐭𝐬 offer rugged alpine capability in a surprisingly agile design. Drawing on over 50 years of Asolo’s expertise in crafting high-altitude footwear, these hybrid approach-and-mountaineering boots have been rigorously tested on Patagonia’s granite cliffs, Alaska’s icy routes, and the volcanic rubble of East Africa.
