At first I ordered a half size larger than I normally wear the BC Converses I have worn before, but as soon as I received them they were a full size larger. I sent them back and ordered a half size smaller. Normally when I wear size 4 men's clothing, it should be without socks; I can wear this size 4 with my socks and they fit perfectly as I originally wanted. I wear women 5.5-6 US.
