Salomon's MM6 Crossderby Puts Black Leather on a Trail Sole

The MM6 Salomon Crossderby arrives October 22 as a glossy black leather derby set on a trail outsole, and it headlines the third release window the two labels have shared since October 2025. Three colorways of the XT MM6 ship beside it on launch day, with a second drop following on November 17. From the ankle up the Crossderby reads as a dress shoe; from the ankle down it is built for mud.

Black Leather Over Mud Contagrip Lugs

The Crossderby pairs a one piece upper in shiny black leather with a rubber outsole in Salomon's Mud Contagrip tread. Salomon's own listing gives the upper as leather, the closure as quickLACE and the heel to toe drop as 11 millimeters, and Sole Retriever describes it as a dressed up take on the trail shoe that trades the hard bottom of a traditional derby for lugs.

Read those three specs in order and the shoe explains itself. Leather in that finish is dress shoe material, the kind that takes a polish and shows a crease. Mud Contagrip is the deep lug pattern Salomon builds for loose, soft and uneven ground, where grip matters more than a clean line underfoot. quickLACE replaces the eyelets and laces of a derby with a single pull cord, so a shoe cut like a formal one closes the way a trail runner does. Each element comes from a different wardrobe, and none of them was softened to suit the others.

Salomon's product page frames the pairing in its own words: it "merges the signature craftsmanship and contemporary creativity of MM6 Maison Margiela with Salomon's unwavering commitment to authenticity and innovation in mountain sports style." The listing still read Coming soon on the eve of the launch.

MM6 and Salomon show the Crossderby on Alexandra, a director and journalist living in London. The previous campaign dressed Deion and Cheuk, two creatives who also live in London, in the XT MM6. Both casts follow one logic: people who work in a city, not athletes on a summit.

Heikki Salonen Built This Partnership, Then Crossed the Table

Heikki Salonen spent 12 years as creative director of MM6 Maison Margiela and was responsible for the label's collaboration with Salomon, which began in 2022. In January 2026 Salomon named him its first creative director, with his longtime collaborator Laura Herbst joining as studio director, according to FashionUnited and Footwear Magazine.

That makes the Fall Winter 2026 range an unusual object: a collaboration whose architect now sits on the Salomon side of it. Before MM6 he spent five years at Diesel, where he was head designer of the Diesel Black Gold line, so a leather upper on a sports label's sole unit is a problem he has worked from both directions. Salomon sits inside Amer Sports, and Footwear Magazine reports the hire came as the brand pushed past its outdoor base into fashion and city wear.

The cadence around the MM6 line explains why a leather derby lands now. Salomon Sportstyle restyled at least four XT silhouettes between mid July and early September, including the XT EVO mainline release that arrived 26 days after Kith's TPU shell version, and followed with the Undefeated Domingo XT 4 on September 10. Those restyles recolored and recoated mesh uppers. The Crossderby swaps the upper for leather, which is a larger change than any colorway.

October 22 Is Drop One of Two. November 17 Brings the Boots.

The collection runs eight footwear styles across two drops, according to Sole Retriever. The first, on October 22, carries the Crossderby and three XT MM6 colorways; the second, on November 17, carries the XT Boot MM6 and more ACS Pro colorways. Sales run through the MM6 Maison Margiela and Salomon websites, their stores and selected retail partners.

This is the third window in twelve months. The XT MM6 first arrived in Vanilla Ice on October 16, 2025, through Salomon's website and select UK retailers. On April 29, 2026 the spring collection brought three XT MM6 colorways on a Speedcross sole, the Cross Dust with a technical gaiter that references both Salomon trail gear and the MM6 dust bag, and the XT 15 Backpack, per Prodism and Jing Daily.

Across the three windows the direction is plain. October 2025 was a sneaker with a Margiela finish. April 2026 added a gaiter and a bag. October 2026 puts leather, a pull cord and a lug sole in one shoe and holds the boots for a second drop 26 days later, on November 17.
