I bought this shoes and there are one size smaller they fut me fine just the front feels a little tight I can't returned them because I had to wear them asap because the other I had were socking wet because it was raining really hard and the shoes fit me fine in the store but when I walked in them outside they felt tight.
put on 3 pairs of thick socks, and wear your shoes around the house. really break them in. fill them with wet newspaper or wet socks, let them dry for a few days. they should be a little bit looser. or, fill a sandwich bag with water, put it in teh shoe, and freeze it overnight. as the water freezes, it should expand the shoes a little bit. good luck with that! thats a bummer :(
