These boots are amazing! they are unique and extremely comfortable! The heal isn't too high and I didn't find they were larger than usual.  I am a 5.5 and I bought a 6 and I don't find them excessively big (as most 6's are a bit big on me).  The only complaint I have is there was a gold lot number on the grey strap but it did rub off with a suede brush so its fine.  Highly recommended and I'm buying every colour!
