I wear a size 8 and bought the 8.5 due to reviews, which was a good thing to do as the shoe runs short.  However, it is too large in the heel, causing slippage.  Another oddity is that the internal arch support doesn't line up where it needs to be.  I'm not sure I'll be able to wear them hiking and haven't worn them as its too hot here.  Other than fit concerns, they appear to be very well constructed and are beautiful!
