I used to own a pair of these Schoodics, but my feet are now too wide to even fit the supposedly "extra wide" size.  It must be the type of last being used, as other Sebago boat shoes don't run so narrow.  That said, quality is top notch - easily my favorite maker of boat shoes (and I've tried all the major makers over the years).

Order at least one size wider than normal and expect to be tight.  I find "extra wide" in this shoe is really no more than medium width in most shoes.
