US7 / EU37 size (Japanese 23.5-24.0 cm) After wearing them for a long time, they felt a little small for me, who usually wears 24cm. These are rubber shoes from the American brand, Oka-B. The color is closest to that in photo 14. Made of rubber material, they are non-slip and waterproof, making them easy to wear on rainy days. They can be washed with water if they get dirty. They have cushioning in the arch and a design that conforms to the foot. These are authentic products purchased at a department store. I wore them about twice, but they felt a little small for me, so I am selling them. The Oka-B logo is slightly faded. Only those who are okay with used items please consider purchasing. I declined the box at the time of purchase, so it is not included. ~Excerpt below~ In 2005, the luxury shoe brand "oka-B" was born on the East Coast of the United States. Focusing on spa shoes for celebrities who frequent top hotels and luxury spas, they developed shoes that are healthy, easy to wear, have excellent design and durability, and are easy to care for. They use the original material "Microplast," which is shock-resistant and soft, and does not slip even when wet, providing comfort. Furthermore, "massage beads" placed based on the principles of reflexology stimulate the soles of the feet comfortably with every step. Also, based on ergonomics (human engineering), they are designed for the ultimate in comfort, so they fit comfortably on the soles of the feet. All Oka-B shoes are easy to care for and can be washed with mild detergent and a sponge. With a design that incorporates the latest fashion trends while maintaining foot comfort, they have spread by word of mouth among celebrities around the world, and have been featured in many media outlets in the United States, making them a brand to watch in Japan as well. - Material: Rubber - Design: With ribbon - Insole color: Blue - Brand name: Oka-B - No box
