I wear size 11 shoes, the standard size for all my shoes is a size 11. I ordered a size 11m, when the shoes arrived they were marked a size 11 EE wide, I thought to come back, I can't wear them , because I thought they were too big and wide. I tried them on and to my surprise they fit(?), maybe a little quality control issue with the size markings. The shoes fit and I have worn them but the size label does not match my size.
