Women's Sandals Model: Sassetta Insole: Padded with Genuine Vegetable-Tanned Leather and stitched Sole: In Natural Leather Heel: In Leather, 3 mm Upper: In Genuine Vegetable-Tanned Leather Color: Leather Each stage of the sandal's production is carried out within our workshop, allowing us to oversee the product from the selection of raw materials, through each individual stage of processing, to finishing, packaging, and shipping to the customer. The sandal-making process begins with cutting the leather for the sole, insole, and heel, and cutting the genuine vegetable-tanned leather for the upper. The assembly of the components is done for each individual customer, taking into account the variations and modifications requested. The coloring is done by hand, at the end, making each sandal a unique piece. The finishing is done with waxes, creams, and natural oils that give a silky touch and an antique effect. Each sandal comes with a certificate of guarantee from the genuine vegetable-tanned leather consortium.
