Just received these shoes and find that they fit very tight for triple-E's. I'll wear them around for a day to see if they loosen up. Otherwise they will go back  Update after two days wearing these shoes - downgrade from 3 to 1 star rating.  They are awful, causing blisters on both feet so bad that I have cut my daily 8 - 10 miles to around 2 miles.  There is no way these shoes are properly sized as 10 3E's and I have requested a return authorization.
