The asymmetric and slightly downturned fit and Bi-Tension randing give the climber extra comfort. Rather than jam toes forward, the rand connects beneath the toes and pulls backwards to the heel structure, the opposite of slingshot randing. The result? Power and precision, married to a stretch-gusseted airmesh tongue for comfort and Vibram®XS Edge rubber. Sticky, energized, comfortable shoes for anything steep, indoors or out.
