I have to say that I like Sebago boat shoes.  I have a narrow foot and find that Sebago is one of the few makers of boat shoes that produces one in a narrow width.  Their shoes fit well, wear well and are comfortable.  This was to have been my second pair of this particular style.  The size was in stock and delivered promptly by Amazon.  The shoe was marked appropriately, 11N, both on the box and on the shoe, however it fit like a size 12N.  I had no way of knowing whether Sebago had changed their sizing model or whether this was just a fluke.  Rather than reorder and go through the returning process, I felt it was more prudent to simply return the shoes and perhaps find them in a retail store where they could be tried on prior to purchasing.
