Butora built the Tight Fit Altura Climbing Shoe for long days on big walls where you&';ll come across every style of climbing except maybe overhanging pitches. Its low asymmetry and flat profile assure comfort when you&';re jamming, smearing, and edging all day. The upper boasts a hydrovelour split leather that stretches to conform to your foot shape, while the odor-resistant organic hemp lining reduces stretching so you don&';t have a baggy pair of boots by the time your reach the summit.
