Five Ten climbing shoes, the white Anasazi model. At the time, it was said to have the stiffest shank in the Anasazi series. I don't know how it compares to the Anasazi Pro. It's a good shoe, so I used it as my serious bouldering shoe, but I rarely climbed seriously, so the sole (C4) still has plenty of life left. I think I wore it for about 10 days. I always wear socks, so I've never worn it barefoot. I think it's a good shoe for those who like a shoe without a downturn and with a stiff shank and STEALTH C4 sole. Returns are not accepted. Thank you.
