The adidas Yeezy Foam Runner MX “Moon Gray” is an innovative piece of footwear designed by Kanye West and adidas. The Yeezy Foam RNNR (Runner) debuted in Summer 2020 and is a cross pollination between a traditional slip-on sandal and shoe. The ultra lightweight design with various perforations across the upper is composed of a mixture of EVA foam and harvested algae. The first edition of the Foam RNNR labeled “MXT,” which seemingly stands for “mixed,” the “Moon Grey” colorway features a marbled blend of dark gray and tan.
