I was just about to ask someone to change it to "sandal-fi" when I read your message. Thanks, but I still see "sandal-case". Could you check it again please?
I'll look into these. I prefer not to have a heel strap, but they probably make a model without one.
Actually, the basic birks have almost no cushioning at all, just the cork and it really doesn't give much. They now have a cushioned version and, I just saw, a version for high arches. I hope to check both of these out.
