I read the reviews and decided to go a half-size bigger - normally wear at 6.5, but got the 7, and very glad I did!  The inside (I guess it's considered the toe box) is very roomy, but my toes just about reach the front inside the shoe.  I think you want it to be roomy, so you can wear some comfy, thick socks.  The boot part is beautiful suede on the outside and soft fleece on the inside.  Probably want to wear w/leggings or skinny jeans to stuff them inside the boot:  1.) because it's probably a bit too bulky under bootcut jeans, and 2.) the dye on the jeans may rub off onto the suede.

Haven't had snow and sleet, yet, so haven't actually worn them out, but looking forward to it.
