The Salehe Bembury x Crocs Pollex Clog “Niagara” is a monochromatic blue-grey colorway of the popular slip-on sandal by the acclaimed footwear designer. The “Niagara” is yet another popular colorway of the comfortable clog that was designed by Bembury. Presumably inspired by Niagara Falls, the “Niagara” colorway features a monochromatic blue-grey hue with textured ridges throughout the upper and sole that form shapes reminiscent of a fingerprint.
