The New Balance Tokyo Design Studio Niobium C1 'Stoneware' is a transformable concept shoe that can be worn three ways: as a waterproof boot, an outdoor mule or an indoor slipper. It is built from stretch ripstop with welded PU overlays and a neoprene collar, with zips down the tongue and around the heel to change the setup, plus an eVent® waterproof membrane. Lightweight EVA foam cushions the step, bungee laces stretch to fit without tying, and a rubber outsole provides grip. Finished in a Stoneware, Thunder Brown and Cortado palette.
