I know this is an old post, but does anyone know if the run large or small? I just bought some mediums since I wear size 44 Sidis and Shimanos, but I'm kind of nervous that they might be too small since one of my pairs of Sidis are Megas. I might have gotten the Large, but I hate going a size up if I don't have to. Am I worried about nothing?
