Man, so mad. Finally found a pair of brown leather Corso after searching for a year, the only size is .5 to 1 size smaller than what I wear. I know Corso runs .5 size large, anyway I can fit if it is full size smaller? I generally wear an 11US, and went a 1/2 size down to a 9.5UK for my Corsos. They still feel a little loose compared to my 10UK Ricards, and with thin socks I think I could have gotten away with a 9UK.
