This is the Propet pedic walker. This women's sandal features a rocker profile and hand stitched construction for flexibility. The adjustable hook and loop closures (2) provide a snugger fit. It's made of a supple nubuck or smooth leather upper. The padded collar and internal heel counter, combined with the removable molded rubber contoured insole with built-in arch and metatarsal support, provide the ultimate in summertime comfort. I'm selling bc I missed the 30-day return window on Amazon, and they are too wide for me. Perfect, unworn condition. NIB
