The adidas women’s UltraBoost Slip-On DNA ‘Black Hazy Sky’ makes use of a blacked-out knit upper made with Primeblue, composed of recycled high-performance materials including Parley Ocean Plastic. Elastic cross straps replace traditional laces, while a molded heel counter offers added stability and support. The sock-like build rides on a full-length Boost midsole, reinforced by a grippy Stretchweb outsole in a pale blue finish.
