This is the fourth pair, we bought from Demar. In addition, we have three boots from others brands that but compared are not at all suitable. One for home, one for the crib and one for our second home one because the liner is unfortunately broke down. Especially the inner shoe is my opinion, but essential, because children always cold feet when it's raining outside and the temperatures drop. Nevertheless full purchase recommendation. Also: cadmium, nickel and lead free. Saying. Hopefully else pollutant free ....
