Once again, it really depends on the shoes and how they fit. I wear anywhere from an 11.5 to a 13 depending on the brand and how tight of a fit I want, and these boots are almost a perfect fit, possibly even a little longer than absolutely ideal. Right now I have a pair of Vans skate shoes that are size 12 and have the cm size listed as 30 (which should be the same as mondo). If I had to guess, I'd say they are pretty likely to fit you, but just from a street size shoe it is hard to say for sure.
