For such a classic look, this adidas Originals sneaker has a lot going on in its title, so let us break it down for you. First off, the "RSPN" isn't some mistaken way of asking you to RSVP or subliminal way to get you to watch Sportscenter; instead, it stands for "Response," which means this is a member of the Three Stripes' refresh of the classic runner, the ZX 5000. It offers a nice balance between the original, with OG styling elements joining modern materials for a more streamlined look. In addition to the red suede overlays, beige leather is used for the Stripes and heel plane while a matching mesh is used to keep the toe box cool. Grey neoprene coats the tongue and collar while an off-white midsole balances the look, while red coats the inner sock liner. Black fills in all of the rest of the gaps of this adidas Originals ZX 5000 RSPN, which can be found now at Caliroots.
