Tenaya Mastia Climbing Shoes - Powerful All-Round Performance

The Tenaya Mastia is a downturned performance climbing shoe that blends structured power with a responsive feel. Support through the forefoot handles forceful edging and dynamic moves, while a split sole keeps the flexibility for technical footwork.

A tensioned construction holds the heel and arch stable for heel hooks and steep movement, and a single hook-and-loop strap makes adjustments quick without losing power transfer. Rubber across the toe box and instep gives grip and protection on modern toe-hooking sequences, and 3.5mm Vibram XS Grip does the rest. Choose the Mastia when you want one high-performance shoe for steep sport routes, bouldering and technical footwork.
