On the size chart I'm nearly a 12, and I'm nearly at the end of these, so they seem exactly the same as the size chart.  I also tried what should have been the equivalent men's size by the charts - 11, but it was over a size too large. It also felt wider.
At first they were very tight, over a few days they have loosened up, but they're still somewhat tight. They seem quite heavy to me, and I prefer light shoes. I guess that's partly the rubber sole, the leather is also thick.
What really annoys me is that as I walk they are pulling my socks down so they end up bunched up inside the shoe. If that keeps up I will be a very unhappy camper. Of course I can't return them any more since I've worn them.

Beware, a return to Amazon because something doesn't fit required me to pay the shipping. Should have bought from zappos - they have them.
