The Nike Vac Tech line has produced several strong silhouettes, including the Nike Air Force 1 High VT “Pewter” that popped up a few weeks ago. Today we preview another Vac Tech design courtesy of the Nike Air Force 1 Hi. Dressed in black wool on the quarter panel, heel, sides, and lace eyelets, the model sports a premium feel without the usual dramatics. For the toe, Nike employes a black leather with the standard perforations over a white midsole. Other details include a black outsole and white laces.
