When Tenaya conceived the new Mastia they wanted not only to create an aggressively curved shoe that delivered maximum power for standing on dime-sized holds, but also one that provided unrivalled responsiveness in all situations. More power and more responsiveness couple to create the essence of the Mastia.

Thoughtful design features abound, such as the sticky rubber covering the upper part of the toe-box and instep, providing both increased protection against abrasion and superior performance when toe-hooking. At the same time, a lightweight and breathable full-bellows tongue adapts to the anatomy of the foot and creates a comfortable barrier between the elastic on the shoe’s instep and the skin. Well, comfortable for a high-performanec shoe, at least.

The Mastia is a crusher on technical vertical routes where you need precision and confidence, as well as the steeps, where power is the name of the game.
