Crupon Trevi Barefoot - Ambra size 40/9.5 NWT Special and different because: - They are made with a natural foot shape that gives more space for the toes. They also have a thin, flexible sole that lets your feet move freely - as nature intended. - Every pair is handmade with love using natural materials and old world shoe making techniques. That means each pair can be resoled and repaired to last you a lifetime! - Our leather is colored only with natural extracts from plants by ancient recipes in Tuscany (Italy), and not like the majority of sandals andshoes from cheap chemically treated leather. Remember that the sandals are shod on bare feet!
