Timberlands Earthkeepers line is extensive, with quite a few styles (from boots to shoes to the sneak-boot hybrid shown here) and plenty of colors to choose from. The company, famous for its rugged workboots, has really greened this line from the bottom up, including linings and footbeds made from 100% recycled PET plastic, recycled rubber outsoles, organic cotton linings and laces, and leather from tanneries that adhere to environmental standards.
