The quality of these boots is fairly poor.  They have not lasted even half the winter so far and I bought 2 pairs.  The "leather" material gives and gives if you put them on a younger kid who runs around in school and the structure of the boot along the sides of the foot where it attaches to the rubber sole stretches out and the foot tends to slide around on the inside of the boot and eventually hang off one side or the other of the rubber sole with walking.
