Known for its commitment to the climbing community Black Diamond brings years of engineering expertise to its Momentum Climbing Shoe--flexibility comfort and durability for the crag and rigorous gym training sessions. We like that it was built with a slim women's-specific shape a lower volume fit and a petite heel cup to keep the fit snug as you send. A breathable and supportive Engineered Knit Technology upper helps this shoe stands out from the crowd while providing some much-needed ventilation in stuffy gyms. The flexible construction comfortably moves with your feet on the wall and won't stretch out after you've put them through their paces.
