ok--i won two pairs of the metallic j.crew flats on ebay. one of them arrived yesterday, and they are SMALL. i am usually a smallish (narrow) 8, and sometimes wear a 7 1/2. i have some other j.crew flats and had to buy an 8.5, but had heard that these ran true, so i ordered an 8.
my toes are all cramped on the sides and the top part of the shoe cuts into my heel. i don't even think that my shoe repair guy can stretch them enough to fit, so i will prob. try to re-sell on ebay and win more in an 8.5 or even a 9. the length is not the problem--it's that they are skimpy on the leather top part, so they're too tight around as opposed to too short in the footbed (if that makes sense).
anyway, i know some people were thinking of bidding on ebay, so there's my review. HTH
