This high-tech boot is built for demanding bell-to-bell riders who require a strong, stiff boot for response, support and comfort. Our instantly-obvious ASYM3F Technology uses an Asym 3D tongue and High Power Dual Zone Boa® System to curve in and follow the natural ridge-line of your foot: Pressure-points become a thing of the past and you get a balanced feeling of support and comfort. The Exo-Spine integrated external backstay links the different parts of the boot together for instant pressure transfer, more support and a locked-in feeling for the life of the boot. The strong ArmorTech materials guarantee durability, and the high-traction B.F.T Vibram® Approach outsole with Vibram® ICETREK compound gives great grip. What’s more, heel and forefoot dampening gel provide cushioning and comfort whilst hiking. The SpaceBlanket insulation and waterproof bladder construction keeps your feet warm and dry, and our new Gold-Level ASYM Thermo Heat Moldable liner keeps things snug. Furthermore, our Ripper-lacing Harness lets riders to tighten the upper and lower closures in one move, even while the boot is closed.
