The Nike Air Max Pre-Day is a silhouette that blends flavor from the 70s and combines it with modern-day design aesthetics. This pair is constructed out of recycled materials including recycled polyester and synthetic suede utilized on the upper. The shoe’s most notable feature is the part of the midsole that is hollowed-out to put even more of a spotlight on the Air unit. Additionally, this pair also comes equipped with an outsole using Nike’s Grind rubber made from repurposed foams.
