I bought two of these, one for my 5 year old and one for the 2 year old. Both were the Concord color, but the 5-year-old boots really look almost black (although it says concord on the box). We wear them in the house only, and they're absolutely great. We've had them 3 weeks, the girls can slip right into them and yet they don't interfere with their cadence AND I bought at least one size too big for both girls (because I'm tired of buying so many shoes, not because they run big or anything). They're warm and comfortable, we haven't had any problem with the wool coming out or even having little bits cling to  the socks they wear inside the boots.

The boots are soft and cushioned, but there's no arch support or anything. Just a flat bottom. For me, that would be no good, but the girls are fine with it.
