The Nike Dunk SB "Chirp" is interesting. Not the full denim upper, we've seen that on Dunk SBs before. Not the fat tongue, the return of which has some heads excited and others looking for their X-Actos. Not even the fur lining, which is kind of like yet another Dunk SB turned inside-out. Not even the patent Swoosh, which complements the denim upper nicely. No, the interesting thing about this Dunk SB (which at the moment only exists in sample form) is that it actually makes a chirping sound when you squeeze the tongue. Seriously. You can check the video. If these ever come out, it would probably be a good idea to keep them away from your dog. Detail shots and video here. [Via Sneaker News]
