Corey A.wrote a review of Five Ten Blackwing Climbing Shoe on August 21, 2017
Familiarity: I've put it through the wringer
Fit: True to size
My use: Indoor bouldering, indoor and outdoor sport primarily 5.9 - 5.12. Have owned them for ~2 months.
Fit: I disagree with most commenters that these run small, I find them true to size. I wear size 11.5-12EE (wide) street shoes. Bought these 11.5 and they are tight but comfortable enough for single pitches without issue. I'm not sure why you'd want a shoe this aggressive to be loose.
-Super sensitive, tacky soft rubber. These are the softest and most sensitive shoes I have owned.
-Reasonably Comfortable. These shoes feel like a very tight set of socks. My toes get cramped if I try to leave them on, but for single pitches I don't have a problem.
-Craftsmanship seems very good
-Will be getting another pair when these wear out.
-These toe into small holds like a dream
_-No real complaints, a few comments:
-You don't want these anywhere near a slab, way too aggressive.
-Softness can mean uncomfortable for long routes, or less than vertical routes.
-While the craftsmanship is quite good, with metal buckles and good stitching, the softness makes me think they wont be the longest lasting shoe.
