The PAMIR is your all weather mountain boot - with modern hybrid construction, total crampon compatibility and sumpuous comfort. The upper construction is a synergistic blend of 2.4 mm split leather and the high tenacity, abrasion resistant Teramida textile (just like Boreal's ICE MASTERS). This puts structure where you need it and breathability where you want it... with excellent fit and a wide comfort range. Toe box is roomy, 3 piece Velcro Tongue System adjusts to your preference and EVA Pro midsole absorbs shock while adding insulation "down under". Triple density PBG-680 rubber out sole grips trail, rock and snow, single layer Thinsulate is right for 3 season climbing and DriLine waterproof protection assures your feet stay dry. A great boot for all mountaineering from the Cascades to the Alps and... Pamirs.
