For performance in crack systems that doesn't blow off razor edges and out of greasy pockets, we lace into La Sportiva's Miura Lace Climbing Shoe. The stiff construction and flat profile increase our comfort in jams and on multi-pitches, while the moderate curvature dials in precision for toeing down in pockets, and the forefoot midsole insert and firm Vibram XS Edge rubber increase our security on edges.
