Designed with French big-mountain legend Xavier De Le Rue, the Deeluxe XVe Boa Splitboard Boot was crafted with the longest days and most demanding missions in mind. Armed with just about every feature imaginable to tackle terrifying chutes, couloirs, and spines, this expedition boot handles big-mountain business with unrivaled performance and protection. Boa and C3 lacing allow the heel, forefoot, and shaft zones to be isolated and tightened separately. Hiker Flex construction uses an upright shaft position with an expanded range of motion that enhances the boot's performance when hiking or skinning. Precise stitching and sandwich construction, paired with a D-Tex membrane, ensures you're protected from the harsh elements all day long, keeping your feet warm, dry, and happy. Plus, rounding out this boot, you'll notice a rugged mountaineering-inspired outsole. This Vibram East Ridge sole gives you the mountain goat-like grip needed to ascend steeper faces and climb precipitous ridgelines. Deeluxe also added a plastic backwelt with a grooved heel for rocking semi-automatic crampons in treacherous terrain.
