Nike Little Posite One GS "Rainbow Pixel" in Light Smoke Grey / White / Blue Fury colorway. They feature a light smoke grey Foamposite upper that has a subtle iridescent sheen, and the midfoot plate and outsole show off a rainbow pixel gradient. The design is kids' exclusive version, inspired by the adult Nike Air Foamposite One. Generally fit true to size. However, the fit can be snug; some suggest going a half-size up to ensure enough room.
