KEEN sandals. The size is listed as 18cm, but they run small and have a shallow instep, so I used them when my child was wearing 16-17cm shoes. They are well-made and in good condition, but they are used and have been stored at home, so please check the photos and understand before purchasing. Shipping is planned for the purchase date + 2-3 days. Keen KEEN Sandals Kids Children Boys Slip-ons Navy Blue
