Love these Robeez!  I'm a big fan in general & wanted a warm pair for the winter, these are perfect!  I ordered the 18-24 months for my almost 18month old & they fit great, hope this size lasts all winter!  I ordered some taller slip in boots as well (different company), but they are so clumpy when she tries to walk in them, these look so comfortable on her foot.  I would definitely recommend.
