The New Balance 2010 'Grey Days' is the silhouette operating further from its comfort zone than most of its releases have ventured. Reflective metallic overlays and carved-out ribbed detailing give the upper a robotic depth, while a gradient midsole transitions from a traditional platform at the forefoot to a black contrast sole at the rear. The ABZORB foundation keeps it grounded underneath a build that has more going on than it first lets on.
