Size 38 but they run large, both in width and length which is my reason for selling. I'd say these would fit an 8.5. Very gently used beige and gold chunky platform sandals by 4CCCCEES. Worn fewer than three times. Some very light markings as pictured. Super comfortable and easy to walk in. And very fun and unique! Platform is about 2.6" at its highest. Originally $350
