Converse Japan’s loafer series has been one of the more quietly compelling threads running through Japanese sneaker culture in 2026. Since the All Star Squaretoe Loafer debuted in February with its removable tassel and sleek smooth-leather upper, the silhouette has sat at a precise intersection of dress-code formality and streetwear ease — the kind of shoe that reads as leather footwear to a client across a conference table but carries All Star DNA for everyone who knows to look. Now Converse Japan is pushing the line further with the All Star Squaretoe Loafer SA, releasing July 31 in Black (31318480) and Deep Brown (31318481) at ¥18,700.

The suffix matters. SA isn’t a colourway descriptor — it signals a redesigned iteration, and the distinguishing detail is right there on the saddle: rock-influenced metal studs that inject a grunge sensibility into what was already a considered, dressy silhouette. It’s a deliberate tonal shift, turning up the edge on a shoe that already walked the boundary between the office and the street.

stir

The All Star Squaretoe family has been one of Converse Japan’s most considered recent projects — a sustained argument that the brand’s iconic canvas-and-rubber DNA could credibly translate into tailored-adjacent territory. Where the original All Star Squaretoe introduced a squared toe profile in leather, departing from the brand’s traditionally rounded shape, the Squaretoe Loafer released in February 2026 went further by rebuilding the upper as a loafer pattern entirely, complete with a removable tassel that allowed the wearer to toggle between a traditional tassel loafer and a cleaner coin loafer silhouette.

That February drop — available in Black (31316981) and Dark Brown/Black (31316980) at ¥17,600 — sold through quickly. The hybrid concept landed precisely because it resolved a tension that many buyers in Japan’s working wardrobe were navigating: the need for something that reads as put-together without the stiffness of a formal dress shoe. The smooth leather upper with its measured sheen, paired with an All Star outsole unit built from lightweight and flexible materials, delivered on that brief. The result was something that felt like a sneaker but moved through dress-code spaces without friction.

Converse reimagines the classic penny loafer with premium leather, silver stud detailing, and signature All Star DNA in black and brown colorways.

flow

The SA variant carries forward everything that worked in the original — the square toe silhouette, the quality smooth leather upper, the removable tassel functionality, the lightweight outsole construction — but introduces a specific modification that changes the mood entirely. The saddle area, which on the February model was clean leather, now features rock-taste studs. That’s the official Converse Japan language: ロックテイストなスタッズ, a phrasing that tells you exactly what register the brand is reaching for.

It’s a small intervention with significant character impact. The saddle stud detail borrows from a tradition of hardware-accented leather goods that runs through Japanese subculture and international rock fashion alike — the kind of detail you find in biker boots, Vivienne Westwood-adjacent pieces, and the harder end of Japanese menswear. On a shoe that was already trading on the tension between formality and street-readiness, studs don’t just add visual interest; they introduce a third element, a grunge undercurrent that makes the loafer read as something more confrontational than either a dress shoe or a clean sneaker-hybrid would typically suggest.

The official product description from Converse Japan frames this as グランジ感が漂うアイテム — an item with a grunge atmosphere — and that framing is accurate. The SA isn’t trying to smooth out the contradiction between its elements; it’s leaning into it.

struct

The upper is constructed from smooth leather with a measured sheen — substantial enough to signal quality, restrained enough to avoid looking overdressed. The saddle section, the defining feature of any loafer silhouette, carries the stud detailing that sets this iteration apart. The tassel remains removable, preserving the two-way functionality of the original design: wear it with the tassel attached for a traditional loafer register, remove it for a more minimal coin loafer profile.

The midsole and outsole continue the approach established in the February model — lightweight and flexible materials that prioritise all-day wearability. This is where the All Star lineage becomes practically important: the outsole provides the kind of cushioning and flexibility that a conventional leather shoe at this price point gen cannot deliver. Sizes run from 22.0cm through 28.0cm, then jump to 29.0cm and 30.0cm. Origin is Indonesia.

Black (31318480) is the cleaner of the two options — a monochromatic read that lets the saddle studs register as texture rather than contrast. The glossy All Star outsole unifies the silhouette from toe to sole, giving the stud detail a setting that reads as considered rather than chaotic.

Deep Brown (31318481) is the more textured proposition. Where the February drop used a Dark Brown/Black split — brown upper against a black outsole — the SA’s Deep Brown is described without a contrasting outsole qualifier, suggesting a warmer, more unified tone across the shoe. Deep Brown also works harder against the stud hardware, allowing the metal detail to catch differently against a richer ground.

Both colourways are available at the same ¥18,700 price point, a ¥1,100 increase over the February model that reflects the additional hardware work.

There’s a specific buyer profile for the Squaretoe Loafer SA. It’s not for someone who wants a clean dress alternative — that’s what the February model handled well, and it’s still available for that purpose. The SA is for someone who wants the utility and dress-code legibility of the loafer format but needs the shoe to carry a harder edge. The studs give it an attitude that reads immediately in contexts where the original’s quiet elegance might have felt too neutral — a live venue, a creative office with no dress code, a wardrobe that trends toward darker, heavier pieces.

The two-way tassel functionality still applies here, but the character of the coin-loafer configuration shifts when the saddle studs are exposed without the tassel softening the hardware. Removing the tassel on the SA reads more aggressively than removing it on the original.
