The La Sportiva Karakorum Evo Gore-Tex Boot is a classic and a crampon-compatible mountaineering boot made from high-quality Perwanger leather. The entire boot upper is made from a single sheeth of leather with added Gore-Tex fabric for increased waterproofness and breathability. This construction requires a lot of skill and expertise but results in a super-durable boot. The long-reaching lacing and the high-cut fabric shaft featuring soft cuffs are easy to adjust for perfect wearing comfort. This sophisticated design increases stability without adding weight.
