Tenaya Mastia is not only an aggressively curved shoe that delivered maximum power for standing on tiny holds, but also one which provided unrivalled responsiveness in all situations. More powerful, more responsive, this is the essence of the Mastia and one which required the focus on every aspect of the process, designing and redesigning each element until the perfect balance was achieved. 

Features: 

• The upper portion of the toe box and instep are covered in extremely sticky rubber, which offers better toe-hooking performance and enhanced protection against abrasion.
• Full bellows tongue with a lightweight, breathable design that conforms to the shape of the foot to form a cozy barrier between the skin and the elastic on the instep of the shoe.
• Two-part sole increases capacity to adapt to the form of the rock.
• Fits like a glove.
• Precision fit and design holds the arch and heel of the foot snugly and securely.
• Its design and applied technology help to increase climbing shoe control by relieving pressure on the toes.
