Innovation really is at the core of Nike, pushing the boundaries of performance to have you beating records without even knowing it. It’s this innovative nature that inspires the women’s Zoom Double Stacked, but it’s toned down for everyday wear. Despite the athletic-inspired visuals, it’s a casual sneaker. One that takes the tech and uses it for comfort rather than performance. The stand-out is the sole unit, with traditional foam replaced by a trio of bright volt Zoom Air units – one in the forefoot and two stacked up in the heel. But the upper is of note, too. Lightweight black mesh is overlaid with a hit of luxe leather at the heel and finished with the faint outline of a Swoosh around the toes.
