I have owned Rocky boots before. I ordered these boots and a pair of Ironclad Rocky boots at the same time. both in a 10.5 D which is what  I wear in just about everything! The Ironclad boots fit great and are very comfortable. These boots were WAY too big!! Like a size and a half too big. My foot literally flopped around inside them. Sent them back... Rocky makes a great boot no doubt not sure what happened on the ones I got...
