Nike Blazer AC Nike is taking a laceless approach with this Blazer AC. And, it really works. The simple design of the Blazer features a large swoosh, white midsole, and "Nike" stitching on the back heel. When you combine that with three Velcro straps instead of laces, it comes together proper. The Blazer AC also sports a fresh black upper with a stunning purple swoosh and inner lining. With the obvious success of this design, look for more Blazer models sportin' the laceless look in the future.
