Salomon XT-4 OG 'White/Lunar Rock/Night Sky' (L49187100) — Archival OG Heritage Reissue

What Is the Salomon XT-4 OG ‘White/Lunar Rock/Night Sky’?

The Salomon XT-4 OG ‘White/Lunar Rock/Night Sky’ (Style Code: L49187100) is a faithful reissue of one of Salomon’s most significant archival trail running silhouettes — the XT-4, the generational predecessor to the XT-6 and a foundational shoe in Salomon’s cross-trail running heritage. The OG designation is not marketing language: it means this reissue is faithful to the original — same last, same construction approach, same proportions and design details as the archival XT-4, not a redesign and not a lifestyle adaptation. The ‘White/Lunar Rock/Night Sky’ colorway is the XT-4 OG in a three-tone celestial palette — clean White, warm textured Lunar Rock grey, and deep Night Sky navy — that gives the silhouette one of its most atmospheric and collectible expressions. At $160, the XT-4 OG commands a $10 premium over the standard XT-6 colorways ($150) in today’s lineup, reflecting its archival status and OG construction fidelity rather than a technology add-on. Unisex, US M4–M11 / W5–W12 / EU 36–45.

Specs & Construction

The Salomon XT Lineage — Where the XT-4 Sits in the Heritage Sequence

Salomon’s XT (‘cross-trail’) series represents the brand’s lineage of technical trail running shoes designed for racing and performance across multiple terrain types in a single outing: dirt, rock, root, mud, wet surfaces, and brief road sections. The XT series evolved through successive generations — each designated by number — as Salomon refined the construction, last, and technology stack for the demands of competitive cross-trail running. The XT-4 is a mid-sequence generation in this lineage — predating the XT-6 that became Salomon’s cultural breakout silhouette. It represents Salomon at a specific point in its trail running design evolution: technically fully formed, before the XT-6’s more aggressive layered upper aesthetic had fully developed, with a profile that is more compact and original-era than the XT-6’s later construction language. For collectors and trail heritage enthusiasts, the XT-4 is significant precisely because it is not the XT-6: it is the shoe that the XT-6 grew out of, the design generation that established the construction logic and performance DNA that the XT-6 would later amplify into cultural prominence. The OG designation confirms that this reissue is faithful to that specific generational form: Salomon has not updated the last, modernized the construction, or adapted the silhouette for lifestyle use. The XT-4 OG is what the XT-4 was, brought back.

The ‘White/Lunar Rock/Night Sky’ Colorway — Celestial Three-Tone

Each of the three tones in this palette occupies a distinct position in a carefully considered spectrum from light to dark, warm to cool:

White is the primary base — clean, bright, and direct. Not off-white or cream but a luminous white that creates maximum contrast against the other two tones and gives the XT-4 OG’s multi-panel upper its crispest, most structured reading. White here is a design decision as much as a color: it foregrounds the shoe’s construction geometry.

Lunar Rock is a warm, textured grey with earthy undertones — the color of weathered granite or basalt, the surface material of the terrain Salomon’s trail shoes were designed to perform on. It is named for the appearance of lunar regolith: porous, mineral-dense, and warm-toned rather than the cool blue-grey of standard neutral greys. On the XT-4 OG’s panels, Lunar Rock reads differently in different lights — closer to stone in shade, closer to sand in direct sun. It is the palette’s grounding element.

Night Sky is a deep, saturated navy-to-midnight blue — dark enough to read as near-black in low light, but with unmistakable blue depth in direct illumination. It is the color of a clear sky approximately 45–60 minutes after sunset: not the navy of daytime sky, not the black of full dark, but the specific deep blue of astronomical twilight. On the XT-4 OG, Night Sky provides the palette’s depth and anchor, preventing the White and Lunar Rock from reading as too light or too warm. The three tones together — White (light, cool, structured), Lunar Rock (mid-tone, warm, textured), Night Sky (dark, cool, deep) — form one of the most balanced and atmospherically considered colorways in the XT-4 OG lineup.

XT-4 OG vs. the Salomon Lineup — Where Heritage Meets Current

Choose the XT-4 OG if you want the archival predecessor — the silhouette that came before the XT-6 and is being brought back faithfully, with a more compact original-era profile and the specific collector value of an OG reissue.

Sizing — Unisex Conversion Table (Men’s / Women’s / EU)

This shoe uses men’s / unisex sizing. Women typically size down 1 size from their women’s US size (e.g., women’s US 8 → men’s US 7 / EU 40). True to size. Size up half for thicker trail socks.

Who Is the Salomon XT-4 OG ‘White/Lunar Rock/Night Sky’ For?

Three buyer profiles: the Salomon heritage collector who knows that the XT-4 is where the XT series’ design DNA was formed and wants the silhouette that preceded the XT-6’s cultural moment — the XT-4 OG is the shoe the XT-6 grew out of, and an OG reissue is the only way to own it at true-to-original fidelity; the OG reissue buyer who values the specific collector proposition of a faithful archival restoration over a redesigned or lifestyle-adapted version — Salomon’s use of ‘OG’ is a commitment to construction fidelity, not a marketing suffix; and the considered colorway buyer who wants the White/Lunar Rock/Night Sky’s three-tone atmospheric palette — one of the most versatile and considered colorways in the current Salomon lineup, with the wide styling range that comes from having three tones that span light, mid, and dark simultaneously.

A: The style code is L49187100.

Q: What does ‘Night Sky’ look like?
A: A deep, saturated navy-to-midnight blue — dark enough to read as near-black in low light, but with unmistakable blue depth in direct illumination. The color of a clear sky in astronomical twilight, approximately 45–60 minutes after sunset.

Q: Is the XT-4 OG true to size?
