Mine are the lower heeled ones, and they are ridiculously comfortable for such a shoe. I was not expecting that at all, even from the lower heels. I think I ended up going a half-size up from my usual size, and my feet are slightly narrow and fairly low-volume. I've tried a couple of knock-offs (the Sam Edelman -- I think it might have been called Ollie?), but the straps were too loose on those.
I was just thinking we need some unseasonably warm weather so I can break those out.
