Fair Harbor is going into the shoe business.

Through a collaboration with Rothy’s, which creates knit-to-shape shoes from recycled water bottles, the sustainable apparel brand will introduce a limited-edition men’s capsule for summer. Both brands have a mission to turn post-consumer waste such as discarded water bottles into wardrobe staples.

The Fair Harbor x Rothy’s capsule will include two shoes and one piece of swimwear. The shoe styles include the Ravello Boat Shoe that is being created using Rothy’s proprietary knit-to-shape method and is made from 100 percent recycled materials. There’s also a washable flip-flop made from recycled plastics as well as the Bayberry Trunk, Fair Harbor’s bestselling swim trunk made from 11 recycled plastic bottles, which has been updated in an exclusive print for the collaboration.

“We’re incredibly excited to announce our upcoming partnership with Rothy’s — a collaboration rooted in a shared vision for sustainability and style,” said Caroline Danehy, cofounder and chief brand officer of Fair Harbor. “This limited-edition collection celebrates our aligned missions to create products that not only look good, but do good too. Inspired by coastal classics, our design teams reimagined timeless staples with a modern, sustainable twist — including a heritage boat shoe, flip-flop and sun-washed swim trunk.”

“This collaboration was a natural fit — two brands with a shared commitment to ending plastic waste coming together with a common purpose,” added Jamie Gersch, chief marketing officer of Rothy’s. “Both Rothy’s and Fair Harbor believe in reimagining what plastic can be: not disposable, but durable, purposeful, and full of potential. Made from recycled plastic bottles, this capsule is proof of what’s possible when sustainability leads the way.”

The boat shoe retails for $159, the flip-flop for $49 and the swim trunk for $92. The capsule will be available for sale on the Fair Harbor and Rothy’s websites and at the Rothy’s stores beginning Thursday.
