The Tom Sachs x Mars Yard 2.0 Crib is a collaboration between Nike and the New York-based artist designed for infants and toddlers. This version of the shoe comes without the overshoe shroud released previously, and is made with a laceless, slip-on fit and dual pull loops in red contrast for easy changing and a jolt of color. The adjustable top strap secures active feet in place, and the one-piece, icy-blue outsole has durable rubber treads for non-slip function.
