Discover our natural materials



Whether in the sole or as an upper - you can now find cork in each of our shoes. It is grown in Portugal, where the cork oak harvest has a long tradition. We support the Portuguese tradition and economy and benefit from short transport routes. The extraction of cork is particularly environmentally friendly, since only the bark of the tree is used and no oak has to be felled. Within nine years, the cork oak forms a new bark, which is then carefully peeled by hand. A peeled cork oak binds three times more CO² than unshelled trees.

The cork shoe is ...

  • temperaturregulating for a good foot climate
  • water repellent for a dry wearing
  • odorless against an unpleasant smell

We also attach particular importance to the origin of our materials, so the wool lining for our hut shoes comes from Spain and Portugal, and the wool felt comes from Italy. We get the muesling free merino wool from a Portuguese spinning mill.

We have wool for your feet because ...

Coconut fiber is a by-product of coconut milk. The fiber is the core covering and serves as protection for the actual fruit. After several weeks of storage in water and subsequent drying, the coconut fiber is processed into fabrics or, for example, for the construction industry into thermal insulation mats. We use the coconut fiber on the bottom of our insoles.

  • moisture control for a dry foot

We are always on the lookout for materials with which existing resources can be used and with which we can reduce our ecological footprint.
