The shoes fit really well. My heel doesn't slip at all. Toe box is snug and comfortable. I do wear somewhat thick socks with them, and I'm sure those help with the fit. (They did not help with other shoes I tried.)
I have also been out on the driving range twice, once to hit a bucket of balls and once for a lesson. My feet were very comfortable and didn't slide around in the shoes. And my golf instructor, a rather senior fellow, thinks they look cute. I agree.
