OP snow boots, size 21cm (fits like 20cm). They were said to be too small and hurt their feet, so they're unused with tags...(TT) If your child's foot size is exactly 21cm, they might be too tight >_< They would probably fit a child with a 19cm or 20cm foot perfectly. They look warm with the fleece lining, perfect for this time of year. Great for snow sports, playing in the snow, or everyday wear!
