I've been wanting to purchase these boots for quite some time and finally bought two pair - the grey and the brown. They fit true to size (cannot wear with thick socks) and, as with most Earth shoes and boots, are EXTREMELY comfortable. They are lightly lined, which makes them nice and soft, but I probably wouldn't wear them in the summer because I think my feet would get too hot and I don't think they'd be warm enough for winter wear in the northeast either. Perfect rain boots for fall and spring, however. Would love to purchase them in other, brighter colors too.
