Slippers, slip-ons, it says thats size 38-39, but they are too small on me and I wear 39 (which is 9 in American sizes). I would say its size 7-7/5. The color is dark orange or like a brick color. The measurements in cm are included. The sole length inside is 23 cm/9 inches. Very lightweight, non-slip, waterproof. Perfect for the gym pools, gym showers, beach, inside or outside wear.
