The Nike SB Dunk Low J-Pack - Shadow sees the return of the Air Jordan 1-inspired color blocking as part of Nikes full-on Dunk revolution of 2020. Following the initial "J-Pack," meaning "Jordan Pack," of 2005 that included "Bred" and "Royal" looks for the Dunk, Nike SB taps into more nostalgia on this colorway that is no doubt inspired by the Air Jordan 1 Shadow.
