I bought these boots for myself and both of my daughters.  As recommended, we bought 1/2 size smaller (I wear 9.5, bought 9).  Felt a bit snug in the toe at first but within 1 day they were very comfortable!  A little loose in the heel, but that's ok - they are just fine and still easy to walk in.  Wear them bearfoot - no sliding socks, comfy warm inside.  I'd highly recommend these boots.
