I found a pair of Jimmy Choos that I love and want for my wedding...on the official website they are $695. I found a couple of other sites that offer them for $133 and $185...are these knockoffs? I never really buy high end designer shoes because they are normally too expensive so I am not sure what to make of the price difference. If they are knockoffs do they still fit like the originals? And lastly for any girl who normally wears JC open toes pumps, do they run small so I will know what size I should order if I decide to get them.
