Keen Footwear for all adventures: Shoes, boots, sandals. Each year, KEEN and its significant suppliers complete the Higg Index. Managed by the Sustainable Apparel Coalition, the Higg Index is a tool used by companies all over the world – including KEEN – to elevate sustainability in manufacturing by measuring impacts and monitoring progress in reducing environmental impacts. The Higg requires that they examine all aspects of their company’s operations from materials selection, to shipping, to end of use, and solicit input from employees across the company, including product engineers, operations mangers, and product developers.
