What Our Gearhead(R) Experts Are Saying:"I use the Mastia when I want maximum feedback without giving up power. The split sole flexes naturally for smears, but the shoe still edges incredibly well thanks to its structured midsole. The toe rubber sticks beautifully on hooks, and the fit feels secure without crushing my foot. It's one of the most balanced high-performance shoes I've climbed in."We reach for the Mastia Climbing Shoe when performance needs to feel instinctive-when the route demands force on tiny edges one moment and delicate friction the next. Tenaya shaped the Mastia with a precise, aggressive curve that channels power into the forefoot, all while preserving the responsiveness we rely on for quick adjustments on vertical and overhanging rock. Its construction adapts fluidly to the terrain, helping us stay confident on shallow pockets, thin cracks, and sloping holds that require unwavering focus. With a microfiber upper, breathable bellows tongue, and a split sole tuned for adaptability, the Mastia blends structure and softness in a way that elevates our footwork. Super sticky toe rubber enhances security during hooks, while the midsole and multi-layer insole work together to sharpen precision on edges and improve feedback on friction-based moves. RBRX and SXR Dynamics technologies support smoother transitions from one position to the next, allowing us to move naturally while maintaining full control. Whether we're bouldering hard problems or climbing steep sport routes, the Mastia gives us the balance of comfort and power that keeps us pushing forward.
