size 7.5 in the old 5.10 size please
Splendid, what a coincidence I've got the spot on shoe size for you.
However, you may have a few issues with the rest of the body that comes along with it. Unless you have spare knees, right ankle, right shoulder and don't mind piercings. Oh yeah, and the body in question is weak as f*ck and is probably best left to run up and down hills.
