These are cute shoes but I think the way the straps are made in the rear of the shoe coupled with the fact that the soles are heavy, made this shoes go from side to side at the back. I  bought them because of the Orthoheel footbed which once cured my plantar fascitiis but my heel would stay planted in the correct place because the shoe kept flopping around in the back. Didn't work for me. They were returned,
