Ecoalf and Michelin have jointly developed their first shoe sole made from the rubber “wasted” in mainstream sole production. The developers set out to strike the best balance between eco-friendly manufacturing and a high-performing product. Following a string of tests, they decided to use 20% recovered rubber to maintain a high level of performance in the soles, which will feature in the new “John Moccasins” collection of moccasins for men and women, available from March 18. The process cuts down on the amount of raw materials used, limits waste and improves manufacturing efficiency by not only reducing the number of steps, but also CO2 emissions and water consumption.
