Made with at least 20% recycled material by weight. Whenever you see the Nike Sunburst or the name Next Nature (NN), you see one more step on our journey toward zero carbon and zero waste. Using synthetic materials, the design features materials that echo mid-1980s basketball shoes. Padded, low-cut collar looks sleek and feels great while the perforations on the toe and sides add comfort and breathability. Vulcanized construction fuses the outsole to midsole for a streamlined look that's durable and comfortable.
