The body of these clogs is made of linden wood, which is light yet strong. The upper leather, a vegetable-tanned suede leather from cattle, is nailed to the wood. A leather strap protects the cut edge of the upper leather. The lining leather is also a vegetable-tanned, soft smooth leather from cattle. The outsole is made of grippy rubber. A leather patch on the heel further enhances comfort.

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.
