Complaints about this shoe were "small toe box" and "slips at heel."  Initially, I ordered size 13 because it was indicated as the best size for me.  The size 13 shoe was too small and slipped at the heel.  I reordered size 14, and I am in love with these shoes!  They are very comfortable, fit perfectly, and do not slip at the heel, even though there is a wee bit extra room.  In short, they run small. Order one size up and, hopefully, like my 14s, they will fit perfectly!  As an additional note, when I wore them for the first time in my league play, four other guys had the exact same shoe, and all of them like theirs as much as I do mine.
