Technically flatform sandals (because of the evenly raised platform), these fashion sports sandals have polyester canvas straps secured by velcro, an EVA insole and a fine rubber outsole.
Generally, these Teva Universal Flatforms are very comfortable and cushioned. They provide arch support thanks to the arched outsole that molded great to my high arches.
Overall, Teva sandals fit a bigger, and this style is no exception. I recommend sizing down a half to full size when buying the Teva Universal Flatform.
They're excellent sandals to walk in thanks to the upturned outsole and soft, yet firm footbed. And they're much more robust and sturdier than you might expect.
