If the Black Diamond Momentum Hook-and-Loop is perfect for beginners, then we believe that the Momentum Lace Climbing Shoe is the next step. Although it still boasts the same comfortable, flat last with neutral asymmetry as the hook-and-loop version, the Momentum Lace features a stiffer flex and a tighter fit to give you slightly more precision. This shoe best serves climbers who have a smarter technical prowess than most beginners, but not the strength necessary for overhung climbs yet.
