ACRONYM is a very prestigious clothing design agency that Nike has teamed up with for a very limited pair of sneakers. So limited in fact that its rumored that the only pairs belong to Errolson Hugh who is a co-founder of the brand. The Nike Dunk High AC is a black leather and wool dunk with the company’s logo embossed on the heel and tongue Nike Dunk High - Euro Champs - Germany. The AC is for the Autoclave soles that we have seen popping up on so many new Nikes.
