Dulio, trained as an aerospace engineer, has worked in the design of three dimensional objects. He has used this experience as he explores and redefines the challenges of mass customization within the footwear industry.

Sergio Dulio, by training a master in aerospace engineering from the Polytechnic of Milan, joined IBM in 1984 as a member of their first technical support team to the 3D CAD/CAM application CATIA. During this time, he also got in initial contact with the footwear world introducing some of first families of shoe specific CAD / CAM applications. Later, he worked for ATOM, one of the leading companies in the field of shoe machinery, as an expert of leather cutting technology.

In the past decade, he coordinated a number of innovative projects for SINTESI, a footwear research consortium with the Italian National Research Council ITIA–CNR. In 2001 he was appointed by ITIA as the technical coordinator of the EUROShoE project, one of the largest EU funded projects in the footwear field, with 33 partners and a total budget of 17 million €, aimed at the development of technologies for the design and manufacturing of customized shoes. In 2003 he gets a contract with CNR – ITIA to organize, install and activate a Design and Mass Customization Laboratory in Vigevano (the capital of Italian shoe manufacturing), where a pilot factory for the production of customized shoes has been put in operation.

He currently works as a technical consultant for ASSOMAC (Association of shoe machinery producers) and ANCI (Italian association of footwear manufacturers) and helps private entrepreneurs to master the challenges of mass customization in footwear.
