Our Materials

From researching the very best yarns on the market to sourcing durable colourful cottons and stylish fastenings. All our materials are chosen to create the highest quality handmade footwear and keep our impact on the planet to a minimum.


Created by Mother Nature herself, wool is a natural and sustainable fibre grown by sheep on a simple diet of sunshine, water, fresh air and juicy grass. Made as part of a natural cycle that is gentle on the planet, wool is warm, durable, naturally insulating, and has antibacterial properties. Perfect for creating snug and warm slippers.
Combined with a touch of high-quality acrylic or bamboo yarn to create a unique sturdiness and durability to your slippers. Each slipper is finished with an antiskid soft suede sole that is handstitched into place with care.

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

  • regulates temperature
  • minimizes odour


Known as the “golden fibre” due to its versatility, jute is second only to cotton in its production and wide 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 jute. Adding an organic rubber sole to the jute soles of your espadrilles offers extra durability.

Eco-friendly & unique
Icelandic Lopi wool

From one of the oldest and purest breeds of sheep, Icelandic Lopi wool uniquely contains two different types of hair. The coarse outer layer is long and water-resistant. Underneath is a finer, short hair creating a softer layer of insulation. 
Lopi wool takes fibres from both layers creating a soft breathable yarn that’s durable and flexible. This wool puts the sturdy in the sturdiness of our slippers. 
Oh, and Lopi wool is made in the most environmentally-friendly way. Free-grazing sheep and using renewable energy in the production process.
