The 11 Best Sustainable Men’s Slippers


Thought is a sustainable brand that started in 1995 with a small collection of beachwear made of natural materials. It has grown to make a wide range of sustainable and ethical apparel, including some very cozy slippers. The Yoko Wool Men’s Slippers are plastic free and made of 100% merino wool. Thought uses recycled paper for its labeling and mailing bags and their garments bags are made from compostable cornstarch.


Naadam makes sustainable cashmere by partnering directly with local herders in the Mongolian Gobi Desert. The brand is committed to delivering high-quality cashmere apparel at a price that’s fair to consumers as well as to the herders. They’re committed to sustainable and ethical business practices and publish an annual Social and Environmental Impact Report.

Naadam offers a range of slippers made from materials such as wool, cashmere, recycled polyester and Bloom™ insoles made from an algae based foam. Made with premium materials, their slippers are breathable yet extremely cozy and warm.


The Allbirds Wool Dweller slippers are made with 60% upcycled scraps from their wool shoes and 40% GRS Certified Recycled Polyester. They also feature an FSC® Certified natural rubber outsole. The slippers are promoted as carbon neutral through using natural materials and offsetting emissions by funding high impact carbon projects.

My personal slipper choice isn’t marketed as a slipper at all. The Allbirds Wool Lounger is a slip on shoe, but it’s as comfy as any slipper I’ve ever worn. Made with a soft ZQ merino wool, the Wool Lounger is toasty, breathable and machine washable. The best part is, they are a minimalist slip-on shoe so you can go from lounging in them to wearing them around town.


Kyrgies makes hand-crafted, natural wool house slippers designed to be warm in the winter and cool in the summer. The slippers are made by artisans in Bishkek, Kyrgyzstan using fair trade labor practices. Kyrgies is Climate Neutral Certified, is a member of 1% for the planet and contributes to One Tree Planted to support global reforestation.

Kyrgies sustainable men’s slippers are handcrafted with wool made from mulesing-free sheep raised on small family-run farms.

The slippers are also colored using low-impact, chemical-free dyes.

Soft and warm, their slippers are made with natural wool from New Zealand and 100% natural crepe rubber. They feature natural latex soles and glue sustainably harvested from rubber trees. Since the slippers are handmade by skilled artisans, each pair will have a unique look and feel.


Freewaters calls its vegan sustainable men’s slippers “house shoes”. They are made with faux-wool, recycled materials and have an outdoor-quality rubber outsole for versatility. Their eco-friendly house shoes feature a knit upper designed to keep your feet warm and comfortable without overheating.

They even offer a spring weight version for warmer weather. The house shoes have Supreme Foam footbed arch support and are machine washable. Freewaters contributes 1% of its sales to fund clean water projects around the world through local partners.


Gumbies Outback slippers are made with a recycled rubber outsole to make them wearable outside. To keep them comfy inside, the upper is a soft brushed felt made with recycled PET made from post-consumer recycled bottles. And the insoles are a soft foam made from naturally derived castor oil.

The Brumby Boot is made from the same materials as the Outback, but in a style inspired by iconic Australian work boots. Gumbies makes all its flip-flops and slippers largely from recycled materials and has committed to planting one mangrove tree or recovering plastic from the ocean with every purchase through partnerships with environmental organizations.
