The mix of materials throughout the upper deliver a predominantly-muted aesthetic, but collars, branding on the tongue and “haphazard” stitching at the profiles introduce vibrant “University Blue” flair to the mix. Yet, the retro’s most eye-catching details are arguably those constructed with up-cycled factory floor scraps as part of the company’s “Move to Zero” initiative: everything from the fabric found at the toe box and heel to the sidewall logos feature a grey and multi-color look made possible by the grinding down of excess materials collected throughout Jordan Brand and Nike’s manufacturing processes. Nike Dunk-reminiscent sole units also partake in the sustainability efforts, with midsoles opting for a Crater Foam build, while tread uses the aforementioned Nike Grind solution.
