UPDATE 11/10/25: New in-hand photos of the atmos x Salomon XT-4 OG GTX “Stars Collide II” have been revealed. A release date is expected in December 2025.

Original Story 10/8/25:
Atmos and Salomon pair up for the second time in December 2025 for an eye-catching take on the XT-4 GORE-TEX.

The collab is called “Stars Collide II. Blending technical performance with a star-studded aesthetic, this trail-ready silhouette is inspired by their previous collaboration. A blue and silver color story is accented by crystals throughout the upper, mimicking a night sky.

Salomon’s XT-4 GORE-TEX offers a rugged, all-weather design. The GORE-TEX materials allow it to handle rain, snow, or any tough terrain while also providing a stunning visual.

A continuation of the Salomon x atmos’ original “Stars Collide” collaboration, the sneaker retains its technical DNA while also upping the ante on its collectible, lifestyle aesthetics. This formula is part of the reason why the XT-4 remains one of Salomon’s most coveted silhouettes.

The atmos x Salomon XT-4 “Stars Collide II” is expected to drop in December 2025, most likely in Asia only.
