Out of Scarpa's entire selection of approach shoes, the Women's Crux Air Shoe is by far the airiest, lightest, and most comfortable option for warmer weather. It features the same Vibram sole as Scarpa's technical approach shoes, even with a MegaGrip rubber compound constructed specifically for slippery rock surfaces. Scarpa strapped this Vibram sole to a knit upper for lightweight comfort and airy breathability that you'll enjoy when it's warm enough to climb comfortably.
