Love these shoes but the sizing is way off.  I ordered a size that was 1/2 to 1 size smaller than normal.  I like to add orthotics to add an extra layer and if it weren't for those I would have had to order down an additional 1/2 size.  These seem super wide as well -- especially for someone with narrow feet.  So, my recommendation is order ~1 full size down and you may still need to go smaller.

Also, they are very cute!  :)
