Sustainable Materials

All our footwear is handmade from natural, renewable or repurposed materials to keep our impact on the planet to a minimum. 


Created by Mother Nature herself, wool is a natural and sustainable fiber grown by sheep on a simple diet of sunshine, water, fresh air and lush grass. Made as part of a natural cycle that’s gentle on the planet, wool is warm, durable, naturally insulating and has antibacterial properties. Perfect for creating warm, cozy slippers. Combined with a touch of high-quality bamboo to create the unique sturdiness and durability of your slippers. Each pair is finished with a soft suede sole that’s carefully hand-sewn into place.

Known perhaps best as a staple for pandas, bamboo is one of the world’s most sustainable resources. The fastest growing grass, up to 47 inches a day and doesn’t need replanting after harvest due to its vast root system. Created using plant fibers, bamboo viscose is known for its softness and breathability. It’s also 100% biodegradable. 


Soft white fluffy balls grown in a protective seed, cotton is used globally more than any other natural fiber. A durable textile offering soft, breathable all-year-round comfort, cotton is ideal in hot humid climates, as the fabric “breathes” absorbing perspiration that evaporates through the material. Leaving feet feeling fresh and airy.

Known as the “golden fiber” because of its versatility, jute is second only to cotton in its production and broad range of uses. Spun into strong, coarse thread, jute rope is traditionally used for espadrille soles. Naturally cooling and completely environmentally-friendly we didn’t tie ourselves in knots with our decision to use this material. Adding an organic rubber sole to the jute soles offers extra durability.
