Yesung was wearing a pair of sneakers from brand Louis Vuitton. Sorry for the pic, I couldn't find a proper Yeye's pic.
I haven't got the buy link and the exact price for this sneakers, but if you see the brand, I bet it's more than 500 bucks. And I'm still searching for Eunhyuk's shoes in this pic, it looks like it has a robot's head printed on it, I wonder if that shoes has transformer printed. Anyone knows about his shoes? Please tell me if you've found the brand. ^^ since it's really cute
