Now made from at least 20% recycled materials by weight, Nike has refreshed a classic that keeps the original integrity with a minimized impact. Crafted with synthetic leather, the Nike Dunk Low channels vintage baller style and simple living onto the streets. The brand’s “Move to Zero” pinwheel logos appear on the Volt insoles to complete the design. 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.
