Tenaya Mastia Review
This especially comfy shoe offers balanced performance for sport climbing and bouldering
Downturned and slightly asymmetrical, the Tenaya Mastia isn't quite as aggressively shaped as other popular bouldering shoes.

Our Verdict
The Tenaya Mastia performs similarly to other top-end bouldering and sport climbing shoes, but it's much more comfortable than many of those other aggressively shaped shoes. The Mastia utilizes super-soft uppers that seem to have a bit more stretch and conform really well to your foot, especially where your toes knuckle up, a common point of discomfort. Climbers who struggle to find the right fit from other brands should put these on their shortlist.

Our Analysis and Test Results
The Mastia is a great choice for climbers looking for more support on overhanging boulders and sport climbs. But it lacks the overall support for longer vertical routes. Credit: Dom Rickicki
Likes
The thought of torquing your foot into some oddly shaped, downturned climbing shoe isn't anyone's idea of a good time. But with the right fit, even a tight shoe can feel comfy. The upper materials on the Mastia are softer than those on many other shoes we tested and conform better to our feet. The mesh liner that sits over the instep also helps reduce the chances of instep pain.
Even though the Mastia is more comfortable than other high-performance shoes, it's no slouch. Like other aggressively shaped bouldering shoes, it does a particularly good job of blending the ability to smear and pull, which is always helpful on steep problems.

Dislikes
Compared to similar shoes, the Mastia felt slightly less precise and sensitive. We didn't notice it as much climbing outdoors, but when we took these shoes into the gym, the lack of sensitivity was more noticeable on slippery artificial holds.
That said, this likely isn't the best choice for an “all-around” outdoor shoe. The Mastia is a bit too downturned for slab climbing, and not quite rigid enough to stand on small holds on a vertical wall. Climbers looking for a crack climbing shoe should surely turn the other way, as the soft and supple uppers offer little protection against torquing your foot into cracks.

Should You Buy the Tenaya Mastia?
It's a comfortable alternative to the usual crop of award-winning shoes from major brands, and performs best on overhanging sport climbs and boulders. Comfort is really what makes the Mastia stand out – our feet were happy for long sessions working on boulder projects. If you're specifically looking for a new bouldering shoe, it's worth popping the Mastia on your foot to see if it works as well for you as it did for us.
What Other Climbing Shoes Should You Consider?
The Mastia is a great shoe; we just think it misses the mark ever so slightly in terms of precision and sensitivity compared to other top shoes. The La Sportiva Solution and Scarpa Instinct VS are both perennial favorites for outdoor bouldering. If you want something a bit softer for gym climbing, check out the Scarpa Drago.
