A partnership rooted in a shared Swiss identity and a mission to inspire the next generation through movement.
Zurich, Switzerland, December 11, 2025 – On and Swiss football player and rising star Sydney Schertenleib are officially partnering. In her role as an On ambassador, she will collaborate with the brand across its Training and Lifestyle verticals.
At just 18, Schertenleib has established herself as one of Switzerland's most formidable young talents, known for her achievements on the pitch for the Swiss National Team and FC Barcelona, as well as for her authenticity, style and cultural influence off of it.
“On’s approach to design and performance feels really aligned with who I am,” said Sydney Schertenleib. “As a Swiss athlete, it’s exciting to partner with a brand that shares my roots and a passion for movement and pushing boundaries. I’m looking forward to working together on the projects ahead.”
By partnering with a homegrown athlete who resonates strongly with Gen Z communities, On continues to strengthen its ambition to be one of Switzerland’s most culturally connected brands. Schertenleib reflects a modern expression of creativity, confidence, and global outlook, with influence both on and off the field, making Sydney a natural fit as the brand continues to expand at the intersection of performance and design.
“We’re thrilled to welcome Sydney to On,” said Alex Griffin, On Chief Marketing Officer. “Her ambitious energy and authentic approach to movement and style align perfectly with our mission to ignite the human spirit through movement. Her strong connection to young communities and inspiring role for young women in particular, make this partnership a powerful addition to our Training and Lifestyle journey.”
