Recycled CDs and Sofa Foam for Your Feet

Shoe manufacturers have been busy burnishing their green credentials over the last few years, incorporating everything from reBut one company appears to be taking the green theme to an extreme, integrating recycled CDs, old sofas, and even water bottles, among other materials, into a new running shoe.
The Green Silence marathon racing shoe, made by the running gear company Brooks and scheduled for release in February 2010, sports heel cups reinforced with recycled CDs; shoelaces, mesh, lining and stitching made from discarded water bottles; outsoles made from recycled rubber; and a collar stuffed with foam from old sofas.
Although Brooks says that the shoe will have half the number of parts of similar lightweight running shoes, those parts will still be shipped from around the world, including water bottles from the United States, Taiwan and Japan, and CDs from Europe — not the sort of “local sourcing” that many environmentalists would prefer.
Still, Brooks says that transportation will account for just 5 percent to 8 percent of the shoe’s total carbon footprint. It also says the midsole of the shoe is biodegradable, although the Federal Trade Commission in the United States has recently expressed skepticism about such claims in general.
Setting aside biodegradability, Brooks said it hopes that runners will retire their used shoes to charities like Soles4Souls, which distributes used footwear to people in need. Nike’s Reuse-A-Shoe program, which takes all athletic shoes – Nike or not — and turns the soles into artificial turf and other products, is another option.
The Brooks shoe is undoubtedly part of a trend toward funkier — and more environmentally conscious — shoes for the running crowd. Another example is a recently released training shoe with toe sheaths that its manufacturer claims “deepens your connection to the earth” and is lighter than most other running shoes.
But Brooks says it’s not easy to make a shoe that will completely satisfy environmental advocates.
“We call this Whac-a-Mole,” said Derek Campbell, the company’s sustainability chief. “Once you hit one button for sustainability, three pop up.”cycled rubber soles to hemp shoelaces.
