i'm thinking of ordering shoes online from the U.S. Can i be confident that it will fit as expected? My feet are pretty normal. In your experience do shoe sizes vary from brand to brand or even model to model? Most of my shoes, regardless of type, are 10 US. Just one or two that are 9.5 or 10.5-11. So 10 is my best bet. I measured my foot and it's exactly 27.2 centimeters, which is just over 10 2/3 inches. If the size is off by 1/2 size, is it better if it's a little tight or a little big? My last pair, a K-Swiss, was size 10 and I think a 9.5 would fit even more snugly, lessening movement within the shoe. Would appreciate help.
