For Fall/Winter 2018, Gigi Hadid Unveils Reebok's "Future Nostalgia" Collection Featuring Aztrek. This version combines classic '90s inspiration with directional style with pops of "sunshine gold" atop a black leather upper.. A signature patch on the tongue and insole symbolize the collaboration. The shoe maintains its performance thanks to the Hexalite midsole and cleated rubber outsole.
