The adidas Yeezy Foam RNNR MX Sand Grey (Infants) is a collaboration between adidas and Kanye West. The shoe was specifically designed for infants and features an MX Sand Gray colorway. The Yeezy Foam RNNR MX Sand Gray (Infants) is made from a special foam material that is both lightweight and durable. The shoe features a perforated design with large openings. The sole incorporates a single piece of foam material that runs the entire length of the shoe. The foam material is soft and lightweight, providing cushioning and shock absorption for the feet. Unlike traditional sneakers that require lacing, Velcro, or buckles to secure them to the feet, the Foam RNNR MX Sand Gray simply slides onto the foot like a sock. This makes it incredibly easy and convenient to put on and take off, which is especially useful for parents of young children. The shoe was released on December 11th, 2021, at a retail price of $40.
