I purchased these from an authorized shop about two years ago and used them for about 10 times total over two seasons, for about an hour each time. They have a navy rubber sole for comfortable wear. They are well-made and durable. My feet are 27cm and these fit perfectly, so they will probably fit someone with feet around 26-27cm. - Color: Navy / Red logo - Design: Thong sandals - Sole: Rubber sole Thank you for looking.
