I am a true size 7.5, but I ordered the size 8 and they fit perfectly.  This shoe is made very well and fits like a glove.  It has a wonderful hidden platform which makes it much easier to walk in.  Now, the toe cleavage.  Yes, there is a good amount of cleavage, which is a big reason why I purchased these heels.  Toe cleavage is all the rage right now, and this shoe does not disappoint.  It certainly takes a common pump and makes it spectacular.  I highly recommend this shoe, maybe not for the office, but definitely for a night out.
