Tenaya Mastia Climbing Shoe

Maximum performance, fine-tuned control.
The Tenaya Mastia is a high-performance climbing shoe designed for advanced and expert climbers tackling steep boulders, technical sport routes, or intensive gym training. With an aggressive downturn, precise toe box, and a secure Velcro closure system, the Mastia delivers the power, fit, and sensitivity needed for high-end climbing.

Built with a thermo-formed heel cup featuring variable material thickness, the shoe ensures a perfect fit and outstanding heel-hook stability. The combination of natural and synthetic textiles in the upper offers both adaptability and breathability, while the Vibram® rubber sole ensures excellent friction on volumes, small edges, and overhanging rock.

Though aggressive in shape, the Mastia offers surprising comfort and precision, making it a serious contender not only for seasoned climbers but also for ambitious indoor climbers looking to move toward high-performance footwear.
