These are BOGS rain boots purchased from an outdoor shop in America. The material seems to be cold-resistant up to -10°C. Although they don't have a boa lining, unlike regular rain boots, they have fabric on the inside, so they don't feel cold when worn. They are US size 6, which is approximately 13-13.5cm, but they seem a bit larger. My child, who has a high instep and wide feet, wore these when they were comfortably wearing 14.5cm New Balance shoes. The insole measures over 14cm. The upper half is made of neoprene fabric, so it's soft, and the pull handles are large, making them easy to put on. My child seemed to run around and move easily in them. The usage period wasn't very long, so they are generally in good condition, but the logo on the insole is slightly worn. They have been hand-washed before listing. The tags in the last two images will not be included, so please check the images. US size 7 is also listed for sale, which I purchased at the same time. If you are looking for comfortable rain boots, how about these? Thank you.
