As part of a greater effort from New Balance to adopt more sustainable practices, newSKY represents an approach towards utilizing recycled materials to create footwear. The upper of newSKY is made entirely from Eco-fi; a high-quality polyester manufactured from 95% PET plastic bottles. Bottles are chopped into flakes, heated, and molded into fiber, creating a strong, versatile fabric. It takes only about 12 bottles to produce one pound of fiber and only about 8 bottles to create an average pair of newSKY shoes. In addition to the environmental benefits of reusing plastic bottles, it’s Eco-fi’s technical qualities that make it an exceptional textile for footwear.
