Kith Celebrates 15 Years With Multi-Year On Running Partnership

Kith just turned 15 and is taking a step deeper into performance running.

The New York label has announced a multi-year partnership with Swiss performance brand On, kicking off with the Kith for On Spring 2026 collection.

The move formalizes a long-term relationship rooted in running, picking up On’s technical innovation and Kith’s design language to create something special. 

Timed to Kith’s anniversary, the Spring 2026 drop introduces two completely original silhouettes: the K-Tech 1 and K-Tech 2.

Both are exclusive to the partnership and built on new Cloudswift tooling, layered with On’s CloudTec cushioning system and dual-density Helion foam midsoles.

K-Tech 1 is positioned as the performance-first model, featuring a breathable mesh upper, synthetic suede overlays, and a custom Kith Monogram treaded outsole.

It launches in Black, Tofu, and Tofu & Sea Moss.

Meanwhile, K-Tech 2 is designed for daily wear and training, with open mesh underlays for flexibility and colorways of White & Real Teal, Thorn & Ganache, and Spirulina & Barley.

Alongside footwear, the brands reworked On’s Core apparel collection across jackets, tees, tanks, sports bras, shorts, and pants, applying Kith’s color palette and co-branded detailing.

Accessories such as the Lightweight 2.0 Cap and Waist Pack Lite 2L round out the range, with select items released through Kith’s Monday Program ahead of the full drop.

A Runner's Tale and a New Run Club

Amid the picturesque product and model shoots, the Kith and On drop kickstarted with a cinematic hero film.

It starts with an elderly man going for an early-morning run on the Brooklyn Bridge.

He then shares his running journey and bits of wisdom with the viewers, all while taking them on a trip around New York.

"Somewhere along the road I realized, travel isn't measured in miles, but in memories, in unfamiliar faces, in days when I woke up somewhere new," he says.

The spot ends with the man, unsure of his destination, finding himself on top of a cliff, watching the sun set. 

The partnership also introduces the "Kith Run Team," a New York-based community initiative training for an upcoming half-marathon.

The team began sessions in February and is set to compete in a New York race this April, further deepening Kith's and On's place in run culture. 

The multi-year commitment is a sign that the brands' efforts are more than a one-off collab, and positions the relationship as a long-term brand partnership.

Why Kith and On’s Long-Term Running Play Works

This brand collaboration shows us how to turn product drops into something consumers can actually take part in. Marketers, take note: 

• Multi-year partnerships are good for framing long-term intent. This helps brands build credibility beyond their typical hype cycles. 
• Exclusive silhouettes tied to the brand app show how controlled access can bring up demand and data capture.
• Launching a real-world run team connects product to participation, strengthening emotional ties with core consumers.

The next few months will be crucial, especially for a brand like Kith dipping its toes into performance running.

Will it evolve from streetwear authority into a credible force within performance running without diluting its core audience?

Our Take: Can Streetwear Win the Long Run?

The two brands are running a marathon with their long-standing partnership.

Launching the Kith Run Team alongside two original silhouettes, we think the brands are betting that authenticity is built mile by mile.

Anyone can slap a logo on a midsole. Fewer brands are willing to train for a half-marathon with their customers.

If Kith keeps showing up at the starting line, this could reshape how fashion labels enter performance categories.

Meanwhile, Adidas recently launched a new campaign for its Superstars line, with Samuel L. Jackson leading a star-studded cast.
