I guess I'd give them 3.5 stars. Here's what I was able to gather when I was actually able to wear these things. Stickiest rubber ever. Seriously. I wanna say Five Ten uses a kind of indy car tire rubber or something similar. Even when just lightly brushing the soles together they stick like nobody's business. They are synthetic so the the uppers stretch maybe a little bit. I stuffed three baseballs into each shoe and tied them over night and that definitely helped. Problem is, and it's definitely my fault, my feet are wide and flat and this was the most painful thing I've ever had on my foot, including a second degree burn. My toes went numb after about thirty seconds and I couldn't put any weight on the heels because my toes would dig into the front and I thought I was going to pass out. When I actually had them on the wall, they were great. Edged like crazy, stuck to smears like there was an extra hold, and hooked into features nicely with the downturned toe. I just couldn't have them on for more than 5 minutes. I ended up returning them. Wear a 10.5 in streets and bought the 11 just to be safe. Big mistake. I just don't think these shoes were meant for those of us with wide feet. Too bad. These shoes seemed badass but I couldn't get past the pain. Oh well. Checking out the La Sportiva Mythos, Spires, and the Anasazi Blancos/Verdes. I would love to stick with Five Ten. Great shoes, great rubber. If you've got the right foot for these, you can't do much better.
