Whether you're new to the vertical world or an old pro, you'll appreciate this shoe's performance in the gym or on the crags. High-quality split leather uppers with lateral straps provide a great fit with minimal stretch. FS-Quattro soles are super sticky and extra durable, even in cold temperatures. Slip-lasted construction offers superb sensitivity, allowing you to feel even the smallest and most marginal hold. Mildly asymmetric shape and superb fit make it an all round performance shoe.
