The adidas Gazelle Indoor is the reason the wider Gazelle family is having the culture moment it’s having right now. While the standard Gazelle has been a lifestyle mainstay since the ’90s, it was the Indoor variant — with its slimmer profile, translucent gum-wrapped outsole, and T-toe overlay — that hit differently when it started circulating through fashion circles in the early 2020s. It became the shoe that fashion editors wore and that started appearing on moodboards before it fully registered as a trend. The Gucci collide gave it a luxury co-sign. The Bad Bunny projects gave it streetwear credibility. And by the time it became genuinely ubiquitous, it had already built the kind of quiet prestige that makes a colourway like this one land with authority.

Now that shoe is carrying the Mercedes-AMG Petronas F1 Team identity — in a Bluebird/Cloud White/Gum palette (style code KJ3264) scheduled for Japan release on 1 July 2025 — and the result is one of the cleaner executions the partnership has produced to date.

The colourway name is doing most of the work here: Bluebird/Cloud White/Gum. Three colours, each pulling its own weight.

Bluebird is the dominant tone across the upper — a cool, mid-depth blue that sits closer to the team’s historic colour story than the more electric or saturated options that sometimes appear in motorsport-adjacent footwear. It’s not navy, not cobalt, not the kind of corporate blue that reads as too literal. It has depth without heaviness, and it reads as classic without being anonymous. On the Gazelle Indoor’s smooth leather upper, which carries more structure and sheen than the suede builds, Bluebird takes on a slightly lustrous quality that shifts across different light conditions.

Cloud White handles the Three Stripes and the T-toe overlay, breaking up the blue in exactly the way this silhouette works best. The Gazelle Indoor’s T-toe is a distinctive detail — a layered, tumbled leather tongue piece that gives the front of the shoe more visual dimension than a flat vamp would — and rendering it in white against a blue base creates the kind of contrast that feels sporty without being garish. The white laces and interior sockliner round out the clean-air freshness of this zone of the shoe.

The gum outsole is, arguably, the element that holds everything together. The Gazelle Indoor’s translucent rubber sole — a design reference back to the original Indoor Gazelle’s clear-bottomed handball specification — wraps around the midsole rather than sitting beneath it cleanly, which gives the bottom of the shoe a wraparound quality that reads as considered and deliberate. On this colourway, the honey-amber translucence of the gum provides a warm contrast to the cooler blue and white above it. It’s the kind of detail that you don’t necessarily read as an intentional design choice the first time you see the shoe, but that you notice you keep looking at.

Mercedes-AMG branding appears on the heel tab, and the full Mercedes-AMG Petronas Formula 1 Team designation runs on the sidewall — a placement consistent across the Originals footwear in this partnership. The tongue tag carries the linear adidas logo. The shoe sits on a leather upper with a textile sockliner, rubber outsole, and regular fit with lace closure, with a total weight of 348g at UK 8.5 — the same construction spec as the team’s other Gazelle Indoor colourways in the 2026 range.

how

It’s worth recapping because the partnership itself is still relatively new and the context gives the footwear drops their significance. In January 2025, adidas announced a multi-year deal to become the official kit and lifestyle partner of the Mercedes-AMG Petronas F1 Team, starting from the 2025 season — replacing PUMA, which had been the team’s outfitter for years. The deal covers the full team including drivers, mechanics, and engineers, and extends to lifestyle product. adidas CEO Bjørn Gulden framed the off-track component explicitly: the ambition was to extend the franchise to a new generation of fans through lifestyle product that felt genuinely rooted in adidas Originals culture, not just badged teamwear.

The partnership dropped its first products in February 2025 — a collection spanning apparel and footwear that leaned heavily into the adidas Originals archive, with the Barreda Decode (a Gazelle Indoor-adjacent silhouette), the VL Court, and the Ultimashow 2.0 all receiving Mercedes-AMG treatment. The colour language across that initial collection anchored on Semi Mint Rush — the team’s signature near-turquoise tone — as an accent across black and white base pairs. It was a strong opening move: brand-adjacent without being overly literal, and built on silhouettes with genuine credibility rather than performance-adjacent models that had no lifestyle traction.

The Bluebird Gazelle Indoor represents the partnership finding its footing and expanding the colour palette beyond that initial mint accent. Moving from Semi Mint Rush as the connective thread to Bluebird as the dominant base is a meaningful shift — it puts the team’s historic colour at the centre of the design rather than using it as a detail.

why

The Gazelle family’s origin story has some relevance here. The adidas Gazelle made its debut in two versions: a red variant with a transparent herringbone sole designed for indoor sports, and a blue version with a microcellular rubber outsole targeted as a training shoe. That original blue was the indoor specification. The Gazelle Indoor’s contemporary revival — slimmer than the standard Gazelle, with the translucent wrap sole and T-toe overlay — is, in part, a return to that original dual-purpose athletics-and-lifestyle premise. Blue has always been the Indoor’s native colour. Putting a Mercedes-AMG team in blue on a Gazelle Indoor is less a coincidence than a closing of a long loop.

The Gazelle Indoor became the defining silhouette of what’s sometimes called the quiet luxury sneaker wave — the period from roughly 2022 through 2024 when the appetite for low-profile, clean-toed, heritage-anchored shoes outpaced the market for anything with overt technology or maximalist construction. It was the Indoor variant whose design brought about the Gazelle trend of the early 2020s, and which the Gucci collaboration was based on. Its continued presence in high-profile partnership projects like this one reflects that it has moved from trend object to something more durable — a silhouette that carries enough design integrity to accept new contexts without losing itself.

For the Mercedes partnership specifically, the Indoor makes sense for reasons beyond heritage resonance. F1 as a cultural property has, over the last several years, attracted a younger and more fashion-attuned audience — partly through the global reach of television coverage, partly through driver personalities and associated media, and partly through the franchise’s increasing presence in fashion-adjacent spaces. That audience’s sneaker taste skews toward exactly the kind of Originals silhouette the Gazelle Indoor represents: clean, recognisable, collaborative rather than performance-coded. A Gazelle Indoor in team colours is a shoe that works for fans who care about both the sport and the footwear independently. That’s a narrower overlap than it might appear, and the KJ3264 sits in it well.

The Gazelle Indoor’s T-toe is worth isolating as a detail that differentiates this shoe clearly from the standard Gazelle. Most people who encounter both models side by side note the Indoor’s notably slimmer last, lower-to-the-ground profile, and the way the T-toe overlay angles across the vamp to create a more structured frontal silhouette. On pairs where the toe overlay is rendered in a contrasting colour — as it is here, with Cloud White against Bluebird — the effect is more graphic and considered than the standard Gazelle’s cleaner, undivided toe. It’s a detail that rewards close inspection without demanding it, which is a quality that makes this kind of colourway work across contexts: readable from a distance as a Gazelle in a good blue, but revealing more considered layering at arm’s length.

The partnership has also been notable for its pricing architecture relative to earlier Mercedes-AMG Petronas footwear under PUMA. The adidas Originals range brings the collab into a price tier that sits comfortably within standard UT / Originals retail — accessible enough to function as gateway product for new fans, priced with enough integrity to sit alongside broader adidas Originals range. That’s a deliberate positioning, and the Bluebird Gazelle Indoor is evidence it’s working.

fin

The Mercedes-AMG Petronas x adidas Gazelle Indoor in Bluebird/Cloud White/Gum (KJ3264) is scheduled for release in Japan on 1 July 2025. Available through adidas Japan and select stockists. The partnership’s footwear drops have moved quickly at retail since the programme launched — the combination of a genuinely desirable silhouette, accessible price points relative to other branded F1 footwear, and a fanbase motivated to collect across colourways has meant limited availability at launch in most markets.

For international shoppers outside Japan interested in this release, the pair is also available through stockists including Stadium Goods, where it has been listed at secondary market pricing reflecting post-launch demand. Checking adidas.com/jp in advance of the July 1 date and adding to cart at the opening window is the most reliable route to retail.

The broader Mercedes-AMG x adidas Originals footwear range — which includes other Gazelle Indoor colourways and the leather Gazelle Indoor Blue listed through the official Mercedes-AMG F1 Team store — continues to expand through 2026, building out a footwear programme that now has genuine depth across silhouettes and price tiers. The Bluebird KJ3264 sits at the core of that programme: not the loudest option, not the rarest, but probably the one that will age best.
