After winning in Grächen (CH) 2019, Leo Páez has conquered, with another outstanding performance, his second World Championship title in Sakarya, Turkey.

At his feet he was wearing Nox, the shoe specifically designed by Vittoria Cycling Shoes, an Italian company leader in the production of mountain bike cycling shoes.


Nox’s sole is entirely realised in XECARB® 1-C30, a thermoplastic composite engineered and produced by Xenia® Materials.

The collaboration between Xenia® Materials and Vittoria Cycling Shoes started a few years ago, when Edoardo Vercelli sensed the possibility to substitute the prepreg epoxy matrix carbon – used in the high-quality cycling shoes’ soles – with XECARB® carbon fibre reinforced thermoplastic composites.

This turned out to be a winning choice, not only because the weight of the shoe significantly decreased, but also because it has been reached the perfect balance between the necessary stiffness to transmit force/power on the pedals and the right flexibility that allows the best comfort on walking routes. This great combination is the key of Nox’s success.

The soles, produced in XECARB® thermoplastic composites, are guaranteed overtime and they have been precisely designed to facilitate the process of mud clearance and cleat connection, possible thanks to the wider shape of the cleat connection area.

Xenia® Materials is an Italian company, specialized in engineering and production of innovative polymer-based materials used for the most advanced and challenging industries.

The company, located in Vicenza, incorporates an engineering team, which helps customers to develop high-tech components with a research and development department dedicated to product innovation.

Established in 1976 by the professional cyclist Celestino Vercelli, Vittoria Cycling Shoes is an Italian company specialised in the realisation of cycling shoes, 100% made in Italy.

After 40 years of innovation, the origins of the company are as clear as they were in its early days.
