Karakoram Flex-Locks
Best stability upgrade for backcountry splitboarders tackling technical, steep terrain.
This simple, effective tool bridges the gap between soft and hard boot setups by adding critical lateral stiffness for steep side-hilling. It offers a significant stability boost for backcountry touring, though it requires a minor trade-off in stride length when engaged.
