With a monochrome Vast Grey tumbled leather and ripstop nylon upper, the Nike SF Air Force 1 Mid Vast Grey is inspired by a military look. The high top ankle has an adjustable strap that combines with a lace closure and a dual zipper system for a customizable fit atop a gum rubber outsole. Details like a looped zipper pull, stenciled branding and multiple heel tabs add to the utility look.
