Rothy’s make their shoes with sustainability in mind. Their goal is to achieve a closed-loop production model by 2023. This means that shoes are designed to last and there will be an end of life solution for every pair of shoes. In 2021 they recycled 20,000 pairs of shoes and in 2022 they are looking at how they can use twice recycled thread into new products. 

Rothy’s own and operate their own factory in China. Their production methods bypass the traditional cut and sew methods and use knit to shape practices which reduces waste. They give thought to the materials they use from recycled plastics, including 125 million plastic bottles which have been turned into thread. They also use algae based foam and natural rubber which both go into making the base of Rothy shoes.

Rothy’s The Point flats are a classic everyday shoe that come in a variety of patterns and colours and are machine washable. Made from sand and plastic, they defy shoe conventions and help you make a more conscious shoe choice without having to compromise on style and comfort.
