Tenaya

When we conceived the new Mastia we wanted not only to create 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 us to focus on every aspect of the process, designing and redesigning each element until we achieved the perfect balance.

The Tenaya Mastia is engineered for elite performance and unparalleled control. As one of the most aggressive models in the Tenaya line, the Mastia is a split-sole shoe that combines downturned precision, exceptional sensitivity, and powerful edging capabilities, making it ideal for demanding climbs.

Recommended use - Vertical and overhanging routes. Bouldering.

Advantages

  • Super sticky rubber covers the upper part of the toe-box and instep, providing both increased protection against abrasion and superior performance when toe-hooking.
  • Lightweight and breathable full bellows tongue that adapts to the anatomy of the foot and creates a comfortable barrier between the elastic on the shoe’s instep and the skin.
  • 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.
  • Aggressive Downturn: The downturned design provides superior precision, allowing for pinpoint foot placements on steep and overhung terrain while maintaining power and control.
  • Split-Sole Construction: The split-sole design enhances flexibility for a more natural foot movement while minimizing edge deformation, ensuring maximum stability and control on small footholds.
  • Thermally Molded Heel Cup: Tenaya's first-ever thermally molded heel cup offers exceptional precision for heel hooking, delivering a secure and stable fit that enhances performance during technical moves.
  • Power Transmission and Comfort: The advanced technology reduces pressure on the toes while optimizing the transfer of power from your foot to the rock, ensuring each movement is efficient and controlled.
  • Single Velcro Strap Closure: The single Velcro strap allows for quick and easy entry and exit, while also providing maximum foot retention, keeping you locked in during your climb.
  • Sticky Rubber Toe Box: The rubber-covered toe box offers additional protection and enhanced grip, making toe placements more secure and durable.
