I am glad that I read the reviews.  I typically wear an 8 1/2 but went down a size to an 8 and they fit perfectly.  I bought the color, Stone and now plan to buy them in black too.  They have just the right amount of sparkle and the studs/spikes add an extra bit of sparkle but in a more subtle way.  The reason I marked them down to a 4 is also because of the studs.  In all fairness, it may just be the way I walk, but the studs hit me in the ankle if I walk too fast and I have actually drawn blood on each ankle. I have to be careful and one day after wearing them my ankles were sore by the end of the day.  They are so adorable though and the price is great that as I already said above - I am getting them in black too.  I didn't find the sole to be slippery once I wore them outside once and they are comfortable enough for a flat with no cushioning.  The stone color is very neutral and I think they will look good with everything from shorts to skirts.
