OUR MATERIALS

The materials in our shoes and accessories have been carefully selected. Above all, we work closely with our leather suppliers. A shoe is made up of many components. For all our products, we strive to improve and find sustainable substitutes for each component, step by step. This is our way of becoming more circular, finally closing the loop. We are committed to having a minimal negative impact on people and the planet in producing our shoes and accessories.

Leather

Leather has unique features when it comes to fit and naturally resists wear & tear. It can also be restored and maintained. Our leathers come from handpicked tanneries, all LWG-rated or in the process of becoming certified. The leather we use is a by-product of the meat industry and as such, it should be purchased and used responsibly. Buy only what you really love, get a lot of use out of it, care for it and then pass it on to someone else!

Leathers

Most of our product are in full grain leather (mainly cow but also from goat, pig and sheep). It is soft, shapes well and is suitable for many types of designs. Plain soft leather is also used for leather linings and leather innersoles.

Suede leather

Suede is either split leather or the backside of the leather. It is matt with a nice structure to it.

Nubuck leather

Nubuck is sanded and treated with oil or wax for a velvety feeling. Kept clean and moist it will last for a long time.

LWG-certified tanneries

Leather manufacturers that are audited and certified by Leather Working Group (LWG). LWG is an organisation focusing on the environmental impact caused by leather manufacturing. All certified tanneries have programmes for energy use and wastewater handling. The certifications are gold, silver or bronze.

Chrome free tanned leathers

In tanning, different natural substances or mixes of substances are used to soften and prepare leather for manufacturing. Chrome is a commonly used substance in leather production. As research indicates that chrome may be a cause of skin allergies, we use chrome-free tanned leather in all leather innersoles and for leather linings worn against the skin.

Textile linings

Our cotton linings are all made of GOTS certified organic cotton. We also use textiles made from lyocell, an even better alternative for the environment. Our polyester linings consist of 100% recycled polyester. As footwear is not generally washed, recycled polyester is especially suitable since it is during the washing process that polyester fibres are released into nature. We also keep an eye out for other alternative textiles, especially those made of vegetable waste. However, it can be challenging to find alternative materials that meet our high quality and durability standards.

GOTS certified organic cotton

Organically produced cotton based on a system of farming that maintains and replenishes soil fertility without using toxic, persistent pesticides and fertilisers. Organic production also relies on adequate animal husbandry and excludes genetic modification.

Tencel™

A textile material made from lyocell and modal fibres, that is, fibres produced from sustainably sourced tree pulp using environmentally responsible processes. Only a fraction of the water used to make cotton is needed to make Tencel.

Recycled polyester, GRS

Polyester material consisting of at least 50% recycled polyester fibres and certified by the Global Recycling Standards (GRS). GRS aims to reduce production's harmful impact and to assure that materials used in the final product have been recycled and processed sustainably. (We always use 100% recycled GRS polyester.)

S.café

An entirely natural substance made from used coffee grinds, which is naturally antibacterial. Rather than coating textile threads with chemical antibacterials, this substance is applied before weaving. You will find this material in the lining of some of our sport shoes, naturally protecting them from odour. Read more.

Outsoles

Outsoles are either made of rubber, thermoplastic materials or low-density materials. Sometimes, a combination of these is used, with the bottom layer being one material and the wedge another. Our definition of rubber is a combination of natural and synthetic rubber. The natural rubber provides good elasticity, and the synthetic rubber resists heat, oil and chemicals.

When it comes to outsoles, there needs to be a balance between durability, softness and looks. To create a long-lasting product, we have focussed extensively on optimally matching uppers and outsoles.

In our Shoe Bring Back program, rubber from worn out shoes is shredded down to become new post-consumer material, an important first step towards circularity.

Outsoles

Non-animal

Products made of non-animal materials such as textiles and/or leather imitation (synthetic) and with cork innersoles. This is a limited part of our collection. See the collection.
