I spotted some other people wearing Louboutin sneakers. I posted on them before. Yunho, G-Dragon and Taeyand also wore them.
Minho wore them on an airport and also in the first episode of City Hunter. Hyunseung wore them several times. Yang Hyun Suk (CEO of YG Entertainment and ex-member of Seo Taiji and the boys) wore them during a recent YG press conference.
