Gomu Gomu 56 Lightweight Mesh Sandals - L Heel: Approximately 7cm * Stretchy rubber knit material that conforms to the shape of the wearer's foot * Soft and comfortable, making them very easy to walk in * Washable shoes for cleanliness * Leg-lengthening effect These are so comfortable, you won't want to take them off! Size L, which is 24cm, but the rubber material allows for some flexibility. Used 3 or 4 times, so there is some dirt on the soles (see photos). I didn't notice any other noticeable stains, but this is just a personal inspection, so there may be oversights. Also, please understand that these are home-stored, used items.
