New Balance's "Grey Days" Promises a Month of Gray Sneaker Drops Rolling out new models and updated older classics. It would be hard to find a New Balance model that isn’t offered in gray. In fact, its affinity for gray dates back to the 1980s and has pretty much remained as its de-facto shade for all of its running shoes and more recently, its lifestyle sneakers as well.The first models to receive the “Grey Day” treatment are the WRPD Runner, a dramatic sculpted sneaker, and the vintage-inspired 1906R, reminiscent of New Balances early aughts running shoes. Dropping May 17, sneakers will come with new materials and textures and a detailed distressed look.
