If you're looking to step your game up to the next level, and you think better feet might get you there, these shoes might just do the trick. I bought my first pair of aggressive climbing shoes a little over a year ago (La Sportiva Solution) and after getting used to the downturn, tightness, and the stretch that comes with such a tight pair of shoes, I started looking for something thats a little more all-around than the Solution. This shoe edges and smears like crazy, and can be sized for all day climbing or intense sport and bouldering on overhangs. From dime edges to big pockets, these toe in to anything and hold on tight, and though their heel isn't quite as intense as the Solution, they will turn your heel into a 3rd or 4th hand all the same. I wear a size 13 street shoe, and wear my shoes as tight as possible (likely you couldn't get any smaller shoes on if you are a 13), to the level of absurd uncomfort, at a 43.5 (the size difference from a Euro equivalent is sizing down from 48.5 to 43.5, a whole 5 sizes. As an additional note, I take my shoes off immediately after climbing a route or problem). To alleviate the fact that these shoes are velcro, I use the velcro as little as possible to keep the attachment as good as possible. No need to overuse the velcro. I'd recommend these shoes if you are looking for a good aggressive sport climbing shoe. They are well worth the money.
