The Salehe Bembury x Puma Velum 2 Nitro in Cool Light Gray/PUMA Silver is built in layers you can count from the side. Sculptural overlays stack across the upper in Bembury's usual language, textured rather than printed, with NITROFOAM exposed underneath in a tone that doesn't match. It's a new silhouette rather than a reworked one. The proportions make more sense on foot than they do in a photo.
