Scarpa's B3-rated Men's Rebel Ultra GTX Boot is ideal for mixed and cascade, fast alpine and alpine rock climbing. A specifically designed carbon mid-sole is tough but very, very light and allows a little bit of progressive flex to enhance climbing sensitivity and approach comfort.
Talking about comfort, the Sock Fit Plus with built in RIBS and the NAG last offer a fit and comfort level more associated to a pair of snugly fitting slippers than some hard-core mountain boots.
Weather protection, durability and insulation is taken care of by the KCN-Tech Fabric on the outside, which is constructed from Kevlar, Nylon and Cordura, and a full Gore-Tex Insulated Comfort Footwear membrane on the inside
An sole and sole unit produce plenty of traction and help save energy whilst on approach with the Re-Active AC sole which utilises Scarpa's Activ Impact Technology.
