When world renowned alpinist/speed climber Ueli Steck has a new gear idea, his sponsors hit the drawing board to turn that idea into product. So when Steck told Scarpa he wanted the lightest insulated boot in the world for his next alpine speed ascent—a tall order—the family-owned Italian footwear company threw out convention and started working on research and development.Scarpa sourced the most innovative and best-in-class materials and combined them for the first time—a carbon fiber midsole for stiffness, Cordura/Kevlar microfiber uppers that are light and abrasion resistant, an insulated Gore-Tex lower boot, and integrated stretch Gore-Tex gaiters that eliminate the need for a secondary gaiter.
The resulting Scarpa Rebel GTX is a super nimble, very light, insulated automatic and semi-automatic crampon-compatible alpine boot that weighs in at just one pound, nine ounces for a size 41. A low-profile stretch tongue and lower-volume alpine last gives the boot a precise, rock shoe-like fit for ultimate climbing proficiency and traction on an impressive diet.
