Purchased the 10 WIDE for my husband who has  a 9.5 shoe size and wears a size 10 regular width in shoes.  Based on reviews, I purchased the size 10 WIDE since it was noted they ran narrow. Unfortunately, he was not able to get his foot in the shoe.  My 13 year old son, with a shoe size of 10, regular width, was not able to get his foot in the shoe either.  His foot is NOT close to being wide - hubby's is.  I have another son who wears a size 9.5 shoe and has narrow feet.  These shoes fit him perfectly.  So, buyer beware...if you are thinking of purchasing these, go to a store and try them on to see what size you need before you order them!
