    FAQ

    Where is Lennertson located?

    We're a Belgian-Dutch company based in the North-Eastern Limburg area of Belgium. Here we do our everyday work like designing shoes and communicating with customers.
    Lennertson is also made up of the countless people who contribute to our mision. Be it our lastmaker in England, our craftspeople in Spain and Portugal, or you who wears our shoes anywhere in the world.

    Sustainable fashion: Where does Lennertson source materials?

    We source our leather traditional tanneries in Europe. European tanneries are strictly regulated by the European Environmental Agency, resulting in far more environmentally friendly tanning practices than in many other parts of the world. We only use leathers that are a side-product of the meat industry.

    As part of our design process, we’re always discovering unique leathers and tanneries.
    Here are some we frequently work with: Boaventura (Portugal), Alaska (Italy), Oehler (Germany), Annonay (France), Dafar (Serbia), Sciarada (Italy), Puccini (Italy), and more.

    Our rubber soles are made by local European, family-run businesses as well.

    Regarding footwear sustainability, construction methods are equally important to sourcing. Our shoes are Goodyear welted, with stitched soles instead of glued. This results in far more sustainable shoes that will last you a very long time and are endlessly repairable.

    Ethical labor: What is Lennertson's policy?

    We grew up as working-class kids and greatly admire the men and women who work on our footwear. Fair & safe labor conditions are essential to us. We produce locally within the European Union, where the highest standards of these laws and rights are guaranteed. We choose to only collaborate with companies that share our values. Being close allows us to visit frequently and maintain a close relationship with all our partners.
