I'm still breaking them in and have worn them for 2 full days.  I ordered my normal size despite recommendations to order a half size smaller and I am glad I didn't listen to that advice or I would have had to send them back.  Overall, they fit very snug on my foot straight out of the box and for the first hour or so in wearing them with socks.  They are stretching a bit but so far they haven't stretched quite enough to be fully comfortable for the full day. I've no doubt they will though.  Solid construction that I expect of any Sperry Topsider product.  I love the style and color and had many compliments on them so far!
