Rainbow Sandals Ron Herman Black Size is likely M, but it's not clearly stated, so it's unknown. Please check the photos of the actual measurements with a measuring tape. I usually wear adidas sneakers in 27-27.5 cm and these fit perfectly. I purchased these at Ron Herman a few years ago and used them for about a year. There are scuffs on the front of both sandals. Please also check the wear on the heels. There are minor scratches, marks, and dirt, but I think they can still be used. Please ask if you have any questions.
