Pre-loved Oofos Oolala Luxe Sandal. Size is a woman's 8, but it runs small. I typically wear a 7 or 7.5 and these fit me very comfortably, see pix. Colors are black and silver. Has Oofoam technology that's super comfy. They have arch support. Very comfortable to walk in. These have been lightly worn and kept in a closet for a bit. Any questions, please ask! Make me an offer or bundle with other items!
