Kulson sneakers are sustainable because we oppose the prevailing mass production in low-wage countries. We stand for controlled and transparent production in Europe and completely avoid plastic. Instead, we work with a variety of innovative and recycled components in our shoes. Our "One" model, for example, is made entirely of vegan corn leather, although you will definitely not notice the difference to natural leather, we promise. Each of our soles is made of 70% recycled rubber and rice husks. As another core element of our company, we donate 4% of the sales price of each sneaker to remove plastic and lost fishing nets from the world's oceans.
