Kanye West introduces the familiar monochrome color palette to his adidas partnership with the Three Stripes with the adidas Yeezy Foam Runner 'Vermilion.' One piece of foam made of algae is incorporated into the innovative slip-on for a sustainable build. In addition to ventilation ports throughout the vamp and side panels, the heel is sculpted to fit snugly around the back of the foot for a non-slip fit.
