You can either throw them away, recycle them, or mail your grandma a fruit cake for the holidays.
Boulder-based Newton Running has an altogether different and environmentally friendlier approach.
According to EnvironmentalLeader.com:
" With help from TDA Advertising and Design, the company designed a new way to package their product - running shoes - in a molded carton made of 100% post consumer recycled material.
Because the shape of the carton fits closely to the shape of the shoe, there is no need for tissue paper. And rather than stuff paper inside of the shoes to help them retain their shape, Newton includes a pair of socks and a reusable shoe bag - one in each shoe, PSFK explains.
Other shoe retailers making effort to be more sustainable include Nike, which released a basketball shoe ade from manufacturing waste in Feb. ‘08, and Adidas, which claimed in March that it is using natural resources more efficiently to produce and package its products."
