Water resistant slip on. Used, great condition with minor marks throughout. So much life left. For Generation Do - the curious go-getters, adventure-seekers and playground puddle-jumpers - the Robbie is here to save the day. Made with a Sugarlite™ upper and ultra-grippy rubber sole, there is nothing the Robbie can't do. Our proprietary material made with a blend of traditional EVA and a sugarcane-derived resin, Sugarlite™ incurs a 22% decrease in greenhouse gas emissions through the production process. Created with the same sole-hugging fit as our beloved Jefferson, you can rest assured these will fit like a dream. Meet your new best friend - you'll change the world together.
