Either these need to stretch or they run kind of narrow & slightly small.  I wear a 10 and the 10 was pretty tight on me.  Also, where it comes across the foot is a little strange because if you wear pants with these, it shows a lot of the top of your foot.  If you have a big glowing white foot like me, it kind of looks funny.  I really like the look of these shoes and the low profile but they're just not a good fit for me.
