Have only been climbing (bouldering) for about 4 months and thought it was time to upgrade from my Five Ten Anasazi Moccasyms. These Five Tens were my first pair of climbing shoes and were flat, basically "up"turned lol (see picture). As my first pair of climbing shoes, I didn't see any weaknesses in them (especially compared to rental shoes). Purchasing So iLL's "Catch" shoe, I could definitely notice the upgrade. The upper rubber helps with toe hooks and the heel grips pretty well for heel hooks since the rubber on the bottom of the shoe and the heel are from one continuous piece of rubber. The downturn helps a lot with small footholds and overhangs. Keep in mind, this review is my experience transitioning from the Anasazis to the Catch (I'm not an expert enough to review this shoe objectively). So far, this shoe is performing very well as I'm working on V5/6s.
In addition to performance, these shoes just look so good. I'm a fan of slippers and the design for the Catch is so sleek/aesthetic. In person, the shoes do have a slight "bog green" tint despite pictures making them seem black and white. It doesn't really bother me. Lastly, the shoes did come with a slight stain on one of the pull tabs and the toe rubber on one of the shoes looked a little dirty. I was a little annoyed at first but realized they would get dirty eventually anyways.
For sizing, my street shoe size is 9 to 9.5. For my Anasazis and Catches, I got 9.5s. From what I've seen online, people would think I'm crazy for not getting a size smaller than my street shoe size. However, mine are actually a really good fit on me. They do hurt after about 30 minutes but breaking them in will help with that.
I totally recommend this shoe!
