Those cute sneakers is from Christian Louboutin 2012 Spring/Summer Collection. They called it Christian Louboutin Louis Spikes No Limit Multicolor Strass. There are few types of this shoes, such as leopard pattern on the inside of the shoes, but as you can see the one which Eunhyuk's wearing only has crystal on it.
This guy is absolutely become one of Louboutin's lovers like me... Great fashion taste Hyuk! xp
