Each model is made by using leftover pieces of rubber in a traditional vulcanization process is what creates the unique marbled look of the outsole. This means that your order can look slightly different from this picture, but it will certainly have the same colour combination. Please note that the left and right shoe will also not be exactly the same, but that is the charm of this kind of partially hand crafted manufacturing. Materials: Upper: 100% cotton Outsole: 100% rubber Produced in the Czech Republic with existing tools and machinery from the past century. Made without glue and entirely vegan, with PETA certificate.
