Featuring our highly-acclaimed Stealth Onyxx rubber for unbeatable friction and durability, the Gambit features a perforated synthetic upper that breaths to keep feet cooler and more comfortable. The perforated synthetic stretches just enough to mold to your foot, and provides an extremely comfortable, precise fit. The Gambit is perfect for climbs up to the 5.11 range, and is the best choice for intermediate to advanced climbers seeking high performance, versatility, and comfort in a lace up shoe that excels on the rock or in the gym.
