Salomon XA Pro 3D x RIER 'White' (L45440600) — Limited Edition Shanghai Luxury x French Trail Tech

What Is the Salomon XA Pro 3D x RIER ‘White’?

The Salomon XA Pro 3D x RIER ‘White’ (Style Code: L45440600) is a limited-edition collaboration between Salomon — the French outdoor performance brand founded in Annecy in 1947 — and RIER — the Shanghai-based luxury fashion house known for architectural minimalism, restrained palettes, and considered material choices. The collaboration is built on the Salomon XA Pro 3D: Salomon’s benchmark trail running platform, defined by the Advanced Chassis midsole, Contagrip outsole, and Quicklace system, and widely recognized as the defining outdoor-meets-street silhouette of the 2020s. RIER’s design contribution is expressed through an all-white monochrome treatment that applies the brand’s signature design philosophy — reduction as revelation — to the XA Pro 3D’s technical architecture: every seam, panel transition, and lug becomes visible precisely because no colorway is present to distract from the shoe’s structural complexity. Unisex sizing, US M4–M11 / W5–W12 / EU 36–45. At $145, it is one of the most accessible price points in the Salomon collaboration lineup for a limited-edition release with this level of fashion brand credibility on both sides.

Specs & Technologies

Salomon — From a French Alpine Workshop to the World’s Trail Running Platform

Salomon was founded in 1947 in Annecy, France — a town on the edge of Lake Annecy in the Haute-Savoie region, at the foot of the French Alps — by François Salomon and his family. The company began manufacturing ski saw blades before moving into ski edges and bindings in the 1950s, becoming a major force in alpine ski equipment through the 1960s and 1970s. Salomon’s move into footwear came in 1992 with its first trail running shoe — a category it helped define and establish as distinct from road running. The XA Pro 3D was introduced in the 1990s as Salomon’s benchmark trail running platform, featuring the Advanced Chassis for torsional stability on uneven terrain — a technology derived directly from Salomon’s understanding of ski binding mechanics and the need for precise, rigid-yet-flexible support on varied surfaces. The XA Pro 3D became Salomon’s most globally recognized silhouette, adopted by trail runners across Europe, Asia, and North America, and by the 2010s beginning to cross into fashion and streetwear — its technical appearance, cagey lug outsole, and Quicklace system making it one of the most visually distinctive trail shoes in existence. By the 2020s, the XA Pro 3D had completed the outdoor-to-fashion transition that the Samba and Old Skool had completed before it: it was simultaneously a fully functional trail running shoe and the most recognizable silhouette in the Gorpcore aesthetic movement that brought technical outdoor footwear into mainstream fashion culture.

RIER — Shanghai’s Quiet Luxury Voice in Global Fashion

RIER (pronounced “rear”) is a Shanghai-based luxury ready-to-wear brand that has established itself as one of contemporary China’s most internationally recognized fashion labels. The brand is built around a design philosophy of architectural restraint: clean lines, considered material choices, a palette dominated by neutrals, whites, and carefully calibrated earth tones drawn from the tradition of Bauhaus-influenced minimalism and East Asian design culture’s own history of reduction and negative space. RIER is not a streetwear brand, not a sportswear brand, and not a logo-driven luxury brand: it is a quiet luxury label whose value proposition is the sophistication of what is not there — no excess decoration, no unnecessary detailing, no color used without purpose. This design philosophy makes RIER’s collaboration with Salomon a precise conceptual match: Salomon’s XA Pro 3D is a shoe defined by the functional necessity of every one of its technical components. RIER’s contribution is to apply its principle of reduction to that technical architecture — to remove color from the equation and ask what the XA Pro 3D looks like when its form is the only thing communicating.

What RIER Does to the XA Pro 3D — The Design Logic of All-White

The all-white treatment is not a colorway in the conventional sense — it is a design decision that reframes the XA Pro 3D as a sculptural object rather than a performance tool. In its standard colorways, the XA Pro 3D’s technical details — the Advanced Chassis plate visible through the midsole, the Contagrip’s lug geometry, the panel transitions of the upper, the Quicklace’s routing architecture — are partially obscured by color contrast and branding. In RIER’s all-white treatment, those same details become the entire visual content of the shoe. The absence of color forces attention to form: every seam becomes a line, every panel boundary becomes a shadow, every lug becomes a texture. This is RIER’s core design principle — ‘reduce to reveal’ — applied to one of the most technically complex consumer footwear platforms available. The result is a shoe that rewards close looking in a way that most sneakers do not: there is genuinely more to see as you look longer, because the white surface makes the XA Pro 3D’s engineering visible rather than decorative.

The Three Core Technologies

Advanced Chassis: Salomon’s proprietary semi-rigid midsole component that runs the length of the shoe. It provides torsional rigidity — resistance to the shoe twisting laterally when landing on an uneven surface — while remaining flexible for forward propulsion. On technical trail terrain (root-covered paths, rocky descents, off-camber slopes), this means the foot has a stable platform even when the surface it lands on is not flat. On pavement and lifestyle use, it simply means the shoe has a more structured, supportive feel than a purely flexible trail shoe. Contagrip: Salomon’s proprietary rubber outsole compound, engineered for multi-surface performance across wet and dry conditions, rock, mud, and trail debris. The lug geometry is multi-directional, meaning it provides grip on both forward movement and lateral loading — relevant for trail running but also simply for confident footing on varied everyday surfaces. Quicklace: Salomon’s single-pull lacing system — pull the cord tab to tighten, tuck excess into the integrated lace garage. No traditional lace-tying. Fast to put on and take off, secure once tightened, and — in the all-white RIER edition — a clean visual element that eliminates the visual noise of lace loops and knots.

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 XA Pro 3D x RIER ‘White’ For?

This shoe is for three distinct buyers who may overlap: the Salomon collector who wants the XA Pro 3D in its most conceptually elevated collaboration expression — not a colorway collaboration, but a genuine design philosophy collaboration; the RIER follower who wants a wearable piece from the brand’s footwear collaborations and understands what RIER’s all-white design statement means in the context of the brand’s work; and the Gorpcore / trail fashion buyer who wants the definitive technical outdoor silhouette of the 2020s in a form that is unambiguously fashion-forward without being decorative — a white XA Pro 3D that performs on the trail and reads as a considered object in any other context.
