The Nike Air Max Pre-Day blends flavor from the 70s and combines it with modern-day design aesthetics. Constructed out of recycled materials including recycled polyester and synthetic suede, 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.
