I bought these the year before last. Originally designed by an outdoor brand, the shoes have a boa lining inside to keep feet warm. They are 18cm, but the width is a bit large, and they might feel small for children with high insteps if they are the same size. Since I live in a warm area, I didn't wear them much for cold protection, but I think people in cold regions would find them useful as they provide good ankle protection. They have been stored in a house with no pets or smokers. I've worn them about 3 times.
