I am a huge climber and 5.10 is the only brand I will buy for shoes, but this shoe is just weird. I got my &#34;street shoe&#34; size, so the length is good, but there is a huge pocket in the heel, and too much give in the arch. As an aggressive shoe I don't find I can trust them on overhangs because of the pocket. I also got a half size smaller than my street shoe and had the same problems... 5.10 rubber so great, so that's a plus for these, but overall they make much better shoes than these.
