Someone in Japan let two pairs of Carpe Diem x CDG boots from S/S 2002 find their way onto Rakuten. Less a collaboration maybe then a special request by Rei to Altieri, and only ever sold in the Aoyama flagship (I think ten pairs or less total.) The first one is the “FIRE” pair and the second is “WATER”: has to do with the unique leather treatments.
Someone already got the first pair, but the second could be yours for about $2k. Do resellers care about C-DIEM yet? These are National Treasure levels of untouchable, like spoken about only in code level, and they popped up on the same site where you might buy Kracie Popin Cookin sets.
