Wigwam Mills in Wisconsin, USA have been producing walking socks for most of the last century.  Since the 1970s they have put many energy saving procedures in place in the production warehouse, all of which help to conserve energy and as a result is better for the environment.  A water system with solar powered panels was installed on the company’s roof  to heat the water which Wigwam Walking Socks have estimated will take about 8 years to recoup the cost back but their philosophy it that they really wanted to make an impact on the environment and do their part to make things a little better for everybody.  So when next buying socks, think Wigwam and their contribution to reducing global warming.
