What Our Gearhead® Experts Are Saying:"The Ribelle HD is one of the most comfortable mountaineering boots I’ve worn. It’s surprisingly lightweight, and the rocker profile makes long approaches feel easier. The HDry® membrane keeps my feet dry in wet conditions, and the Perwanger suede upper is super durable. Plus, with semi-automatic crampon compatibility, it’s ready for technical terrain without the bulk of a plastic boot."When the mountains call, we answer with the Scarpa Ribelle HD Mountaineering Boot. Designed for fast-moving alpine missions, this boot merges the durability of a mountaineering boot with the agility of running footwear. The HDry® waterproof membrane and 37. 5® lining manage moisture to keep our feet dry, whether we’re breaking trail through slush or tackling icy ridgelines. Built with a Perwanger suede leather upper, the Ribelle HD withstands the rigors of rugged terrain while maintaining flexibility for efficient movement. The Vibram® Precision Tech Roll outsole, with its rocker profile, reduces fatigue on long approaches, while the Sock-Fit™ XT construction wraps our foot securely for a precise and comfortable fit. Semi-automatic crampon compatibility adds versatility, making this a go-to boot for technical ascents and demanding mountain adventures.
