i love those sandals. i love the toe strap style. i think it is so sexy. as far as comfort goes, if you can wear thong sandals, this shouldn't be a problem.
they're cute.. i have a few pairs like that, and urban had several similar styles last year, but they are not very comfortable when worn for long hours- what flat/thin heeled sandal is? .. but, just my opinion, i would not spend kors prices on those sandals.. they tend to get scratched up/etc quickly, water usually stains the footbed, etc. and i really think urban/similar stores will start carrying them very soon.
