French born in Austria, Marc Sadler currently lives in Milan. Citizen of the world (he has lived and exercised his profession in France, the United States, Asia and Italy), he collaborates with many companies in the furniture sector, small and large household appliances, lighting, industrial products, and is still strongly engaged in the sports sector with almost thirty-year long collaborations.

At the beginning of the 1970s, Marc Sadler developed the first ski boot in entirely recyclable thermoplastic material, then industrialized by the Italian company Caber (later Lotto), for which he quickly gained responsibility for all the product lines, establishing a long and fruitful collaboration marked by the patent of the boot with a symmetrical shell, which for several years remained the best-selling in the world.

This is the origin of his specialization in sport design that leads him to work with the most important multinationals in the USA, Asia, Japan and Europe, both in sports shoes and in many other sports sectors: skis, tennis rackets, golf clubs, etc. Coming from a branch of industry where research and experimentation with new materials and production processes is more widespread, it allows him to export knowledge in sectors where the concept of design limited to the aesthetic form is rooted.

Awarded with the Compasso d'Oro ADI for Drop (Flos, 1994), Tite and Mite (Foscarini, 2001) lamps, Big bookcase (2008, Caimi Brevetti) and Bellevue ice cream counter with Panorama technology (IFI, 2014) ), has received many other important international design awards.

His back protector designed for Dainese is in the permanent design collection of the MOMA in New York and the Mite by Foscarini is part of the design collection of the Beaubourg in Paris.
