UTMB World Series strengthens partnership with Sidas, specialist in foot care solutions for athletes

Already a partner of the UTMB World Series® events in France, Sidas has become a partner of the circuit for 3 years.

The partnership will cover European events in 2025, including the UTMB® World Series Finals at the HOKA UTMB® Mont-Blanc, and will extend to the entire global UTMB World Series circuit in 2026 and 2027.

UTMB World Series and Sidas are pleased to announce the expansion of their partnership with the aim of providing foot care solutions to UTMB World Series runners during both race preparation and management.

Founded in France in 1975, Sidas has built its expertise around foot comfort solutions for sports, beginning with skiing. Notably, they invented the first custom ski insoles, revolutionizing comfort and performance for skiers. Driven by strong values of passion, performance, and commitment, the brand is now a leader in the field, present in over 45 countries and meeting the needs of runners around the world.

A long-standing partner of the HOKA UTMB Mont-Blanc for over five years and of French UTMB World Series events, Sidas has forged a strong bond with the trail running community, supporting every runner — from beginners to top elite athletes — and already almost 10% of UTMB World Series participants, the brand is committed to working alongside them to optimise their preparation and reduce the risk of pain and injury. This partnership marks an opportunity for runners to better prepare their feet before the race and reduce the risk of injury and pain during it.

Our shared mission is to educate the community on foot care issues in trail running and to provide expertise on available solutions tailored to the specific needs of trail runners. Sidas will share essential information with runners to help them prepare for their races, notably through a foot care protocol approved by the UTMB medical commission. They will also be present at certain UTMB World Series events to offer advice or conduct a static foot analysis thanks to its digital pressure platform, Feetbox® EVO.

In 2025, the company will support runners at 23 European UTMB World Series events, including the HOKA UTMB® Mont-Blanc, which hosts the UTMB World Series Finals.

Céline Prévost, UTMB Group Commercial Director, said:

"We have built a strong partnership with Sidas over many years at the HOKA UTMB Mont-Blanc, working together to provide the best foot care solutions for runners. We are delighted to see this long-standing collaboration grow within the UTMB World Series and become part of its long-term vision. This reflects our shared commitment to offering the best possible preparation, helping participants make the most of their UTMB World Series experience — before, during, and after their race — and achieve their goals as they cross the finish line.”

François Duvillard, CEO of Sidas, said:

"Since 2020, the SIDAS brand has pursued a clear mission: to raise awareness and educate runners on the importance of foot preparation in ultra-trail. Thanks to the unwavering commitment of the UTMB® Group teams and SIDAS' internal efforts to provide foot care solutions allowing runners to fully enjoy their race, SIDAS is now ready to take a new step forward. By becoming the official foot care provider of the UTMB® World Series, runners will have access to personalized advice before, during, and after their race through our awareness campaign "No finish line without footcare." They will also benefit from our comfort solutions and the expertise of our SIDAS teams worldwide."
