Chewing gum is somewhat of a universal pastime, but the consequence is often the amount of gum left on streets when people spit it out. To reduce waste and litter, city marketing organisation Iamsterdam, designer Explicit Wear, and sustainability company Gumdrop have collaborated to design a shoe from the recycled gum. Called Gumshoe, the shoe’s sole is made of recyclable compounds (known as Gum-Tec) produced by Gumdrop, and those compounds are made up of 20 percent gum.

According to the project, roughly 3.3 million pounds of gum make it onto Amsterdam pavements each year, and that costs the city millions of dollars to clean up. The project uses around 2.2 pounds (1 kg) of gum for every four pairs of shoes.

It’s the world’s first pair of sneakers made from gum. Apart from the sole, the rest of the shoe is made from leather. The shoes are available in bubblegum pink or black and red. They’ll be available in June for $232.
