The Crocs Roy in Nightfall is the general release colorway of a silhouette designed by Steven Smith, one of the more interesting footwear designers working today. The fully molded Single-shot Mellow™ foam build carries Smith's exaggerated bubble outsole construction and molded ventilation panels throughout, with flex grooves across the forefoot as the one detail that breaks the tonal slate blue. A clog with a design pedigree most clogs don't have.
