The Mastia is a downturned climbing shoe designed for steep and vertical bouldering and sport climbing. Tenaya shoes are known for their comfort even when sizing down and the Mastia is certainly no exception! It has a shallow low profile toe box which means you can keep your feet flatter in the shoe without having to scrunch up your toes, making the Mastia very comfortable for a high-performance climbing shoe. The shallow low profile toe box also gives you excellent precision and works really well with pockets, thin cracks and footholds that barely qualify as footholds at all.
The Mastia has a split sole, combined with SXR Dynamics and RBRX technologies which give you an impressive intuitive feel. The heel has friction lock technology which keeps your heel sucked into the shoe and it gives you better adjustment, perfect for tenuous precise heel hooks. With a 3.5mm sole, the Mastia is very sensitive and gives you the perfect balance between edging smearing and sensitivity. So to sum up the Mastiais the perfect climbing shoe for sport climbing or bouldering on vertical and overhanging walls.
