Astorflex, a company owned by Fabio Travenzoli, was invented by his father Alfredo who, together with his brother Bettino, succeeded in the business of their father,  Daniele, and of their grandfather Ferdinando.

At the beginning of the 19th century, in Castel D’ario, where the first shoe factory was set up, were lots of small, family-run workshops that produced handmade footwear.

After the first world war, at the outset of industrialization, the small “Fratelli Travenzoli” started to produce different types of footwear using the “ideal” method that's been pursued since 1984.

The lining and insoles are vegetable-tanned calf leather, obtained by soaking the leather in a mixture of water and powdered oak bark and mimosa, without using dies or color finishes.

This process makes the leather healthier, hypoallergenic, and guarantees greater sweat absorption for dry, odorless feet. Most of the soles are natural rubber consisting of coagulated latex from the rubber tree (hevea brasilianis).

The various shoe parts are assembled using water-based adhesives.
