I’m in love with Big Bang’s BSX photos! I guess it took me a while to look at their feet, though. ^^;
The picture makes it a little difficult to tell but these are my best guesses. It looks like TOP and G-Dragon are wearing one kind of shoe, while Taeyang and Seungri are wearing a different one. Daesung has something over his so I’m not sure.
And now, Pierre Hardy strikes again! Remember this post? The boys are wearing the same shoes here:
And in case anyone was wondering, the guitar Taeyang is holding in that second picture is a B.C. Rich Mockingbird:
