BNSM [BENSEM] Basics Natural Spirit in Merino Sneaker, which is made from 100% grown Merino sheepskin. We only use this Merino sheepskin because of its unique property that the fur regulates the heat of the feet itself. No more hot, burning or cold, damp feet. Merino sheepskin offers an optimal feel-good climate for every foot. Because of its fluffy fur, it is also often worn barefoot and also prevents foot odor. This means that the possible uses of the BNSM sneakers are limitless and all year round. In heat and cold, on roads, off-road or in air-conditioned rooms. This makes it the world's first sneaker that is made from grown fur (double face). “An invention of nature. A treat for the feet "
