The Kiko Kostadinov x Gel Korika 'Black' is a collaboration between the Bulgarian fashion designer and Gel Korika. It is part of a four-piece pack that includes two vibrant color options for women and two neutral color options for men. This particular pair belongs to the latter category and showcases a predominantly black design. It combines the tooling of the GEL-NIMBUS 21 with a modified upper borrowed from the GELBURST RS, resulting in a hybrid silhouette.
