The Copenhagen Effect: How a Trail Shoe Became a City Essential

In 2013, Salomon's S/LAB team built the XT-6 for athletes like François D'haene and Kílian Jornet—ultrarunners who measure their training in vertical kilometers and their races in days, not hours. The shoe was engineered for one purpose: to keep feet stable, cushioned, and protected across distances most people will never attempt.

For a few years, it did exactly that. Then something shifted.

The Broken Arm Moment

The first signal came from Paris. In 2015, The Broken Arm—a boutique known for blurring the lines between technical wear and high fashion—approached Salomon about a collaboration. It wasn't a marketing strategy. The brand wasn't chasing streetwear credibility. The Broken Arm simply saw something in the aggressive silhouette and panel-heavy construction that felt right for the moment.

A year later, the XT-6 walked its first runway. Boris Bidjan Saberi sent models down the Paris Fashion Week catwalk in the trail shoe, injecting his avant-garde aesthetic into something built for mountain descents. The fashion world took notice.

"Everybody thinks Sportstyle is three years old," George Egan, Salomon's North American director of Sportstyle, told Gear Patrol. "In reality, it was 2015 when The Broken Arm actually reached out."

Copenhagen's Quiet Claim

While Paris provided the runway debut, Scandinavia provided the streets.

Copenhagen became ground zero for the XT-6's urban adoption. The shoe appeared on the cycle paths of Nørrebro and the late-night walks through Vesterbro—not as a statement piece, but as a practical choice that happened to look undeniably good. Danish retailers like NAKED Copenhagen recognized what was happening before most of the world caught on.

"As one of the first cities to take the XT-6 from the trails to the streets, Copenhagen has embraced the silhouette," noted The Drop Date. A dedicated collaboration was only a matter of time.

The Scandinavian approach to the XT-6 wasn't about hype. It was about function meeting form in that understated Nordic way—technical gear worn with straight-leg jeans and oversized knits, performance shoes paired with tailored coats. The city's fashion-forward residents didn't adopt the XT-6 because it was trending. They adopted it because it worked.

The Accidental Icon

By 2019, Rihanna posted herself in a pair. Google searches spiked. Then came the Super Bowl halftime show in 2023, where she performed in MM6 Maison Margiela x Salomon Cross Lows. Overnight, searches surged by 4,000 percent. StockX named Salomon the fastest-growing sneaker brand on the platform.

But here's what makes the XT-6 different from most hype-driven footwear: Salomon never stripped away the performance DNA to chase lifestyle consumers.

The Quicklace system still pulls tight with a single motion. The Contragrip outsole still grips wet rock and loose gravel. The Agile Chassis System still provides the stability that ultra-distance runners depend on. The shoe that fashion adopted is the same shoe that was built for mountains.

"It's incredible to see how a pure performance shoe can become, in just a few years, a highly coveted piece of fashion," says Maina Souviron, Product Line Manager at Salomon. "It was first created by the S/LAB team for athletes running super technical and long races, and we haven't changed anything but the colors since then."

The New Normal

Today, the XT-6 has moved beyond niche appeal. Collaborations with SSENSE, Aritzia, JJJJound, and Sandy Liang have expanded its reach. Nordstrom stocks exclusive colorways. The shoe that once belonged to Japanese fashion designers and dedicated trail runners now sits comfortably in mainstream rotation.

Highsnobiety put it plainly: "What was once a shoe solely worn by Japanese fashion designers and GORP nerds is now something for everyone."

Some might see that as dilution. But the XT-6's success suggests something else—that when function is prioritized from the start, style follows naturally. The shoe wasn't designed to be fashionable. It was designed to perform. And that authenticity became its greatest asset.

For the Long Run

The XT-6 represents a different path than most fashion-crossover footwear. No celebrity endorsement deals launched it into the mainstream. No limited drops manufactured scarcity. The shoe simply existed, did its job exceptionally well, and waited for culture to catch up.

From Chamonix to Copenhagen. From ultra-trails to cobblestone streets. The XT-6 proves that the best design doesn't chase trends—it outlasts them.
