What Our Gearhead(R) Experts Are Saying: "This shoe is a win for new climbers. It fits snugly without being painful, and the breathable knit upper keeps things cool during long gym sessions. Super easy to get on and off, and the molded rubber holds up way better than you'd expect for an entry-level model." The Momentum Climbing Shoe is made for emerging climbers who need comfort, breathability, and reliable performance from the start. Black Diamond engineered this shoe with a neutral, flat last to support long gym sessions and moderate outdoor routes without overdoing the aggression-ideal for building skill and confidence. The upper features Engineered Knit Technology for zoned stretch and ventilation, keeping feet cool and supported as the session heats up. Instead of cutting from a single rubber sheet, the molded 4. 3mm rubber sole is forged for consistency and comfort-similar to the brand's approach to carabiners. With a single Velcro strap for easy adjustability and a microfabric midsole for underfoot sensitivity, this is the kind of entry-level shoe that keeps progression fun and frustration-free.
