I originally bought these in red about 2 years ago.  I love them so much I bought them in the black/leopard and the gold.  I have the red in a 6.5B and the gold and black in a 6.5C (wide).  Both fit me fine but I definitely have a little more wiggle room in the wides.  I find them to be true to size.  I normally wear a 6.5 and that's what I ordered and they fit perfect. I love that they have some height on them without feeling too tall.  I can wear these all day to work, walk around, and not feel any discomfort.  Now looking for the denim and white in a 6.5C!
