The worst injury I ever had was when I sailed without any shoes, I had to get a few stitches in my foot and could not sail for quite a while that summer....
Regular booties have to much going on with a thick rubber sole and that can get stuck in the footstrap. The "sock" type is much smoother and also provides a better feeling of the board. They are likely less resistant to cuts, I guess, but I have never had cuts deep enough to hurt my foot while wearing them.
