Cloud Tower consists of technical face climbing and long splitters ranging from fingers to baggy fists, and Boreal's Ace Climbing Shoe handles each pitch gracefully. This shoe combines a moderate downturn into symmetric shape, resulting in a shoe that performs on the crux and remains comfortable on the long routes. The full insole and midsole provide plenty of support, and Boreal's abrasion-resistant FS-Quattro rubber stays strong for seasons. The split leather upper features anti-stretch stitching, and there's a full canvas lining for added breathability and durability.
