Tenaya Mastia Climbing Shoes

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.

Microfibre Upper

For super durability and a comfortable wearing experience, the Mastia Climbing Shoes have a microfibre upper. This durable upper keeps feet encased when traversing the rocks or boulders, and with a soft next-to-skin sensation, prevents the risks of irritation or abrasion against your skin. Additionally, the soft, comfortable materials have breathable properties to reduce overheating, whilst quick-drying technology prevents a build-up of sweat and moisture to keep feet feeling fresh. The Mastia has a precise, glove-like fit that holds the arch and heel of your foot nice and snug, which also keeps you secure in the shoes. Working to shield the shoes from damage when scraping against rocks and rough surfaces, the super sticky rubber that covers the upper part of the toe-box and instep also helps to provide you with superior performance when toe hooking. The down-angled, low-profile toe box enables more effective use of shallow pockets, thin cracks and other small footholds across rock climbing conditions. Not only this, but the design releases the pressure from your toes, providing you greater control when climbing. A lightweight, breathable full bellows tongue adapts perfectly to the anatomy of your foot whilst also keeping feet cool. The tongue also means that slipping the Mastia on and off is super easy and quick. Finally, a velcro closure system works to provide a perfect fit and feel, and part of the 'Friction Lock' technology, provides you with precise adjustment and volume control to achieve the perfect fit.

Double Midsole

The Mastia ensures that comfort underfoot is ensured, keeping things soft when stepping or striding across boulders and rocks. This thin, robust midsole is perfect for providing you with a soft landing whilst ensuring the compound is rigid and sensitive so you can feel the rock's characteristics and provide you with structure and power transmission when climbing. A five-micro-layer insole also provides you with optimal transmission of force through all situations, making you feel closer and in close contact with the rock below.

Vibram XS Grip Outsole

Featuring a two-part sole, the Mastia's outsole has excellent adaptability to the surface you're climbing on for total confidence. In a curved form, the split sole utilises a combination of cutting-edge technologies, including SXR Dynamics for increasing the underfoot responsiveness of the shoes, improving the shoe's ability to adapt to different rock shapes and providing more precision and comfort. Alongside this, the outsole utilises RBRX technologies for improved performance for a greater range of responses in all the scenarios you may come across when climbing or bouldering. This also ensures outstanding grip across the rock surfaces, and thanks to the Vibram XS Grip, you have optimum traction on the range of surfaces and textures you may come across, providing you with a more efficient climbing style. The Mastia is as equally at home on hard boulder problems as it is on vertical and overhanging sport routes.
