We live in Wisconsin and these boots are great.  I love them because they keep my daughter's feet warm and if the insides were to get wet during play, the liners are removal.  In the past we have had such a difficult time getting the insides dry in boots that the liners cannot be removed.  They fit as expected.  I bought them a bit big, so she has room to grow.  I am hoping she will be able to wear them this spring and again next fall (at least) . We'll see.  They are not clunky or heavy.  I would highly recommend.
