Barker Shoes enjoyed a positive response to its presentation at the Moda fair in Birmingham and theMicam in Milan of a small new range of shoes whose sole is made of recycled chewing gum and recycled plastic. The original sole is pink for women and blue for men, and it doesn't stick to the ground. The recycled gum comes from Gumdrop, a British company that collects used chewing gum in special containers through the U.K. and recycles it into polymers that can be mixed with rubber or plastics.
