Got these for boy friend.  He has one foot a little wider that the other and his shoes separate in the seam on the little toe side over time.  I got him a pair of these and he absolutely loves them.  He hasn't had the problem with the sides because they are wider.  He loved his first pair so much I got him a couple more, so if these get discontinued he'll have backup's.  Honestly, he raved for days with the first pair !
