[Condition] New, unused, without box [Size] 25.5cm [Product Name] THE NORTH FACE Summit Cayesh FUTURELIGHT The North Face Summit Cayesh FUTURELIGHT [Product Overview] These are alpine boots designed for lightweight performance and compatible with semi-automatic crampons. The double-boot upper features high-strength Spectra fibers for enhanced durability, and a waterproof and breathable FUTURELIGHT membrane, a proprietary nano-film material developed by THE NORTH FACE, created by applying nano-level polyurethane fibers in a micro-layer sheet. The low-cut inner boot utilizes the BOA system's dial control for fit adjustment and retention. This design allows for easy on and off and is designed for a comfortable fit even during extended use. The sole uses Vibram's LITEBASE MONT compound rubber, which balances lightweight performance and abrasion resistance. A carbon fiber shank plate is built-in to increase rigidity and enhance stability during walking. These are uniquely developed technical boots that balance lightness, rigidity, and durability, essential for speed-focused mountaineering styles. Insulation material is not used. Gender...Men's
