I purchased these and it only took a few seconds of wearing them to know that they wouldn't work. I REALLY wish I could keep them - they are a super cool looking shoe, great colors and a non-marking sole; however, my foot feels absolutely contorted in them. I have never had a shoe feel this way on my foot before. I have narrow to average feet with an average arch. If you look at the sole of the shoe, there is a 'waist' where it cuts way in and there is nothing underfoot. It felt like there was nothing underneath my arch and my foot literally rolled inward to compensate for the extremely narrow part of the sole near the arch. Maybe someone with a high arch would do better?
Overall, they fit the width of my foot well - so a wide width foot is probably not suited to these. True to size (though, if you are between two sizes I'd go with the larger one).
