The CERRO TORRE is ready to tackle rapid winter ascents and the wide array of new school of mixed-ice and dry-tooling routes. Whether you are moving at full speed in the mountains or crag climbing with your "points" overhead - light weight is important. CERRO TORREs are near minimum mass employing a high tenacity Teramida fabric body with 2mm full grain leather cuff, lacing overlays and heel counter. This combo is backed up with triple layer Thinsulate for warmth and Boreal Dry-Line for complete weather protection and waterproofness. The CERRO TORRE also features generous padding throughout and Boreal's Ankle Lacing System with Velcro Strap - to suck the rear of the boot in and lock your heels down for extra climbing power.... while maintaining ankle flexibility. Nice too is the stretchy "nail head" cuff with elastic and velcro closure that seals out ice chips and debris. Sole is ultralight TPS-3 with triple density rubber for traction & support and is compatible with all crampons. Midsole is 10mm EVA-PRO for shock absorption and extra thermal insulation. Sold in UK sizes - example, if you wear a US 10.5 (UK9.5) hiking boot order a UK10 (US 11) for an equal fit. Shipped anywhere, anytime. Fit Guaranteed!
