Slightly wide 10.5 foot here, ordered a 10. I tried on the 9.5, 10, and 10.5 and found that, sockless, the 9.5 or 10 would work. I would likely suggest the 9.5 as the 10's have stretch a little more than I expected. In contrast to the mocs, these are quite comfortable and more full bodied. The leather quality a bit poor for the price, but the sole is replaceable and you can also make the uppers a project to refinish when the time comes. I wear them a lot and enjoy them, but the leather is the primary reason for my rating.

I've been wearing Bass boat shoes for years, and this collaboration with Mark McNairy gives a nice bit of flair to their standard fare. The white sole and exposed welt construction are really nice details, as is the slim profile—a rare quality in boat shoes.
