Insole: Nappa leather Nappa leather is a high-quality and very supple smooth leather. Nappa leather is very easy to shape, so it is a very good material for lining the footbed. Footbed material: Cork Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning. Outsole: EVA EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with extremely good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.
