Meet our materials.

From the uppers knit from single-use plastic to the strobel boards made from algae-based foam, our products are the result of expert exploration of repurposing materials. Because at Rothy’s, we’re on a continuous quest to do better—and that means making the right choices from the very beginning.

Single-use plastic bottles.

We divert plastic bottles from landfills and transform them into our signature thread—which we then knit into durable, washable and sustainable styles like shoes, bags and accessories. Who knew plastic could look and feel this good? 

Algae-based foam.

Our strobel boards (aka, the green part of the shoe under the insole) and the footbeds of our sandals use an algae-based foam. Harvesting harmful algae from waterways helps to keep our marine ecosystems in balance—plus makes for extra-sturdy shoes.

Ocean-bound marine plastic.

Collected within 30 miles of coastlines and marine environments, we’ve transformed thousands of pounds of marine plastic into sustainable bags unlike any other. Beyond keeping waste out of the ocean, this cool material is also fully machine washable—just like our signature thread.

Natural rubber.

What else goes into the outsoles of our signature flats and loafers? Our women’s shoes are made with 9% natural, renewable rubber from rubber plants, while The Driving Loafer contains 31% natural, renewable rubber.

Bio-based TPU.

We get back to nature with our outsoles on The RS01 Sneaker, The Lace Up and The Flip Flop. Created with a bio-based TPU (made with corn), these outsoles are flexible and durable—plus they feature a raised detail for added traction.

Natural minerals.

Our women’s styles (like The Point and The Flat) feature eco-friendly rubber outsoles that contain 26% natural minerals (in other words, sand). For our men’s shoes, our outsoles on The Driving Loafer contain 23% of this material.

Castor beans.

Beans in shoes? Almost. The cushy footbeds in The Lace Up and The RS01 Sneaker, as well as the durable insoles in our women’s flats are crafted with a bio-based PU which utilizes castor oil as a more eco-friendly plant source.

Hemp fiber.

Hemp may be one of the oldest textiles on earth, but we see it as the fiber of the future. Strong, regenerative and built to last, this material is blended with our signature thread, cotton and marine plastic (in the case of bags) to create breathable styles—inspired by the beauty of nature. 

Merino wool.

Plush, cozy and natural, we like to think of merino wool as mother nature’s perfect material. Combined with our signature thread, our merino styles are soft and renewable, while just as washable and durable as your favorite Rothy’s.

Recycled packaging.

Made with 95% post-consumer recycled materials, our boxes are strong enough to ship on their own. Plus, we use cardboard inserts that are 100% recyclable and seal our boxes with a blue ribbon that’s made from recycled materials, too. Talk about the whole package.
