The top of the sneaker insoles are made of cork. The benefits of processing cork to the insole are in both comfort and sustainability. In addition to its natural breathability and water repellent properties, cork absorbs impact sound and, thanks to its thermal advantages, has a cold and heat insulating effect. Used for this purpose is the blend of bottled cork production, which is up 75% in the annual production of the 25 billion bottle corks discarded.
