Mastia

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

Advantages

• Super sticky rubber covers the upper part of the toe-box and instep, providing both increased protection against abrasion.
• Lightweight and breathable bellows tongue that protects direct contact of the elastic of the instep with the foot.
• Two-part sole increases capacity to adapt to the form of the rock.
• Glove-like fit.
• Precision fit and design holds the arch and heel of the foot snugly and securely.
• Its design and applied technology contribute to release pressure from the toes for a greater climbing shoe control.

Recommended Use: Vertical and overhanging routes. Bouldering.

The best of both worlds

The Mastia has a perfect balance of features. It is soft yet structured, offering awesome control for precision edging while at the same time providing superb sensitivity and feedback in smearing and friction situations where split-second responsiveness can mean the difference between success and failure.

Built to perform

Its curved form and split sole, combined with our cutting edge SXR Dynamics and RBRX technologies, contribute to a more intuitive, more efficient climbing style. The Mastia is as equally at home on hard boulder problems as it is on vertical and overhanging sport routes.

Every little thing adds up...

Every single design feature of the Mastia is millimetrically calculated, from the seven different formulations of rubber it utilizes right through to the carefully selected materials used on the upper. Its 3.5mm rubber outsole combines with a five-micro-layer insole to provide optimal transmission of force in all situations and make the climber feel closer to the rock. A perforated bellows tongue not only delivers maximum breathability, but also means that slipping the Mastia on and off is just a matter of a few seconds.
