NWOT Native Shoes Robbie slip ons in black and grey. Both pair included in this listing. Size C7. 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 decrease in greenhouse gas emissions through the production process. Take a sweet step forward! Created with the same sole-hugging fit as our beloved Jefferson, you can rest assured these will fit like a dream.
