This coarsely woven sandal made from strikingly grained, vegetable-tanned cowhide is stylistically based on the classic Roman sandal. They cover the toe area at the tip and enclose the foot, ensuring a good fit. At the same time, they still offer enough freedom and airiness when worn. The stitched-through leather sole with rubber inserts provides grip on urban surfaces. An adjustable leather strap with a metal buckle across the back of the foot allows the shoe to be adjusted to the individual shape of the foot.

The beginnings of Astorflex date back to the 19th century. After the First World War, the descendants of the shoemaking family founded the company "Fratelli Travenzoli" in Castel d'Ario, a small shoemaking town in the province of Mantua (Lombardy). From then on, the Travenzolis specialized in making shoes using the "ideal method", in which a visible seam joins the upper material to the insole, making the shoes particularly flexible, hard-wearing and durable. Today, the fate of Astorflex lies in the hands of Fabio Travenzoli, who consistently uses high-quality natural materials in production. First-class Italian leather is used for the uppers, in particular from master tanneries in Tuscany. The lining and insoles are made of soft calfskin, vegetable-tanned in a decoction of oak bark and mimosa. The outsoles are mainly made of natural rubber and only water-based adhesives are used. Astorflex has dedicated itself entirely to "good shoes", as the addition "La scarpa buona" in the shoe manufacturer's logo promises.

The outsole may leave colored marks on the shoe or floor due to abrasion.
