These were gifted to me and only tried on - NEVER WORN (run narrow, too narrow for my wide foot). Original tags thrown away, but BRAND NEW! Make waves. Nine rounded straps come together to form a single wide strap that covers the bridge of your foot. Made to fit like a glove, we added a cushioned insole and rubber outsole for extra-extra comfort. Leather upper Leather insole Rubber outsole Made in Brazil Their website is SOLD OUT in EVERY SIZE!!! ALSO... According to their website: 100% of reviewers would recommend this product to a friend!!!
