We previewed the Rick Griffin x Vans Collection back in January, and we now have a detailed look at the Vans Slip On from that pack. Rick Griffin was an American artist in the 1960s and was most known for his psychedelic poster designs. Those poster images have now made their way onto a fresh pair of sneakers. This pair hosts a black base accented by a white mid-sole, graphics on the upper, and a white inner lining. The Rick Griffin x Vans Slip On is now available overseas, and should be available for purchase in the states in the coming weeks.
