Gumshoes

3.3 million pounds of chewing gum a year are spit out on the streets of Amsterdam. That would be about 574 million sticks of gum. With a population of 850,000 plus 3.5 million visitors a year that works out to 131 sticks of gum per person.

A city marketing organization, a Dutch clothing company and a U.K. recycling company called Gumdrop have partnered to create a sneaker sole made from recycled chewing gum.

Those Chiclets you love to chew aren’t made from chicle, natural latex from a central American tree, any more. Chicle went out in the 1940’s. Now chewing gum is made from “gum base,” probably polyisobutylene (which is also used to make inner tubes), in other words synthetic rubber.

Gumdrop makes pink gum recycling bins which are hung on poles and walls in Amsterdam and the U.K. Gumdrop was able to make a new type of rubber from from the chewing gum and make sneaker soles from it. 2.2 pounds of gum make four pairs of Gumshoes. The gum recycling bins are also made from recycled gum.

The sneaker soles are bubblegum pink, of course, and they even smell like gum. A map of Amsterdam is molded into the soles of the sneakers. The uppers are leather and come in bubblegum pink, black and red. Cost is $232 a pair.

Now everyone can be a private eye. The word “gumshoe” for private detective comes from late 19th century shoes with gum rubber soles, stealth shoes for sneaking around. Originally “gumshoe” meant a thief but by about 1908 came to mean the catcher of the thief.

“Sneaker” comes from Female Life in Prison, By a Prison Matron, pseudonym of the British novelist Frederick William Robinson in 1862: “The night-officer is generally accustomed to wear a species of India-rubber shoes or goloshes. These are termed ‘sneaks’ by the women.”
