Meet Rothy’s. They’re shoes made from recycled plastic bottles. The bottles are washed, sterilized, then turned into a thin plastic fiber that can be fed into a 3D knitting machine and transformed into a pair of shoes in about six minutes. The Rothy’s founders, Stephen Hawthornthwaite and Roth Martin, are quick to highlight the eco-friendliness of their shoes, which minimize waste in the production process and use recycled plastic. And they like to tout how practical the shoes are: they’re even machine washable. At $125 a pair, they’re not cheap, but they may make you feel better the next time you forget to recycle.
