The Nike women’s Dunk Low Next Nature ‘Sail’ gives the ‘80s icon a sustainable build as part of Nike’s ‘Move to Zero’ initiative. The low-top showcases white and off-white tones on a synthetic leather upper constructed from recycled polyester. Standard Nike branding appears in tonal fashion on the woven tongue tag and heel tab, while Nike’s pinwheel logo decorates a Volt-colored sockliner. The sneaker is mounted on a lightly speckled rubber cupsole, featuring white sidewalls and a pale grey rubber outsole Size & Fit Men’s Nike shoes tend to have an equal width between the forefoot and heel. Women’s Nike shoes most often have a narrower heel than forefoot. Some women with a wider foot will often select men’s shoes for comfort, because women’s shoes are often more narrow than men’s shoes. According to Nike, other fit differences between men and women’s shoes include arch length and height.
