FastFeetGrinded has developed a process for recycling used shoes for new uses, including sports floors, footwear and other products. Sports and games can now literally be played “on” old shoes. By shredding the shoes, we separate the different materials that can be reused. We sell these materials back to producers to finance our recycling process. These are FFGRD RUBBER, FFGRD FOAM and FFGRD FIBER.
