Green in Black is a 100% environmental friendly shoe made from waste tires. The vamp uses the same design concept. Since tires have anti-slipping particles on surface, the outsole has strong traction and suitable for all kinds of road surfaces. In addition, the manufacturing process is simple, using as less as possible resources and reducing wastes in assembly line as much as possible. It looks simple but wears comfortable, breathable and light weight. Environmental-friendly will be the future for the shoe-making industry.
