17cm snow boots! They were used for a boy, but they were a little tight, so a child who wears 16.5cm shoes might find them just right with socks. The child was able to play in the snow without saying they hurt!! I think they've been used carefully, but please purchase only if you understand. Please note that I will be out of the prefecture and unable to ship from 6 PM on August 15th to 6 AM on August 19th after your purchase.
