x New Balance XC-72 Marblehead White New Balance’s 990 sneaker is just as comfy and well-crafted as those before it, Blu run-ready mesh with soft suede across the upper. The model’s signature chunky sole — built with ENCAP® cushioning for support and stability — isn’t the most eye-catching thing about this pair, though. Neon yellow accents on the collar, laces and branding add propel finishing Speed.
