In a new pack out of Nike Sportswear, we examine the 3GX Series collection. Over the three-shoe pack, each style shares similar traits in black-leather uppers and white outsoles. The slightest hint of color comes courtesy of a single green eyelet and a leather patch on the tongue. Three styles include the Air Macropus, Blazer Mid ’09 and the Air Zoom Tennis Classic. The pack has begun hitting select retailers around the world.
