I bought this boot in a size 6 (he was 1.5 years old) for my son.
They suck.
I cannot get his foot in them...we had to take the liner out to get his foot in to even get use out of them...even that was difficult trying to put them on w/o the liner. These boots also had plenty of growing room for him.

I now have a 10 month old girl...winter is approaching and this December she will be 1 year old. I have tried these boots on her feet, but again with very frustrating difficulty I cannot put them on her. My husband can't either.

If they had a zipper down the side, there would be no problem.
I hate this boot.
