Please help me

Hi gals! I need some sizing help on the circus city gold pump. Can you please tell me if that pump runs small? Any help would be sincerely appreciated.

I am not particularly familiar with the Circus City pump, and if you are really very concerned, just go try them on at a store, but I personally usually follow this rule: if it is CL flats, I go half size up from my US size, if it is high heels, I look at the material: for patent and materials that do not really stretch (like pvc) I go a whole size up from my US size, and for kid leather, suede and more stretchy materials, I may go only a half-size up, as well. People say CL sizing varies from style to style, however I have not found this to be very true for myself. In my experience all CLs size similarly with the only exception in the shoes' heel height: flats vs 100-120mm heels. HTH
