It's hard to be more eco-friendly than Bionat. Natural non-tinted leathers, vegetable based tanning and 100% natural pure rubber tree milk soles are some of the characteristics of this brand's collections. And to be even more militant, the company is housed in an eco-friendly office with all the latest environmental norms: a wooden structure, bio-climatic architecture, a living roof, and double flow ventilation. With all this, it's easy to forget that Biomat shoes are also respectful of the morphology of the foot and are guaranteed for an entire year!
