Inspired by the concept of zero gravity, the European retailer size? put a twist on its version of the Nike Air Max just in time for 2019's Air Max Day. The size? x Air Max Light 'Zero Gravity' sees the storied sneaker in a semi-transparent grey mesh fabric on the toe box and heel, topped by tonal suede overlays. The branding stands out, featured upside down on both the tongue and heel as a nod to the space travel theme. A traditional foam midsole and visible Air unit round out the look.
