adidas Samba OG vs Onitsuka Tiger Mexico 66: Which Flat?

The adidas Samba OG began as an indoor football shoe: leather upper, suede T-toe overlay, gum outsole designed for wooden court floors, three stripes where you expect them. Everything about it is built for lateral grip and durability. The Onitsuka Tiger Mexico 66 was designed as a running shoe, named for the year Mexico hosted the Olympics, and it carries that history in its proportions — thinner, longer, lower, with the crossed side stripes that later became the most recognisable detail in Japanese sneaker design. The film appearance most people remember cemented it as a cultural object rather than a sports shoe. Both are now sold almost entirely for the street.

What the two are actually made of:

• adidas Samba OG: genuine leather upper with real suede overlays, cup sole construction, gum rubber outsole
• Samba weight: roughly 335 g on the scale, which is substantial for a flat trainer
• Samba fit: true to size, medium overall width, but a narrow toebox
• Samba durability: rated well for both toebox and heel padding in abrasion testing, and a top pick among leather sneakers for longevity
• Onitsuka Tiger Mexico 66: leather upper in the standard build, slim last, thin flat sole, crossed side stripes
• Mexico 66 character: lightweight construction and a noticeably narrower, lower-volume shape than the Samba
• Mexico 66 variants: a woven backless SABOT and a metallic TGRS version joined the line in 2026
• Both: low top, lace closure, minimal cushioning by design

Neither of these is a comfortable shoe by modern standards, and pretending otherwise does nobody any favours. The adidas Samba OG measures low for shock absorption and offers essentially no arch support, which reviewers flag consistently — it gives you a lot of ground feel, which is charming for an afternoon and punishing for a day of city walking. The Onitsuka Tiger Mexico 66 is thinner still, with a flat sole that was competitive in 1966 and is not competitive now. If you are choosing between them on comfort alone, the Samba's slightly thicker cup sole gives it a narrow edge, and both are comfortably beaten by any retro runner with actual foam in it.

The adidas Samba OG has a specific and well-documented flaw: the gum outsole is slippery. It was designed for indoor wooden floors, and on wet European pavement it loses confidence quickly — traction rates low in standardised testing. Against that, durability is genuinely excellent, with strong abrasion results for the upper and a construction that regularly outlasts trend cycles. The Onitsuka Tiger Mexico 66 is the more fragile of the two: the slim leather upper and thin sole are not built for daily punishment, and the 2026 SABOT variant with its perforated woven upper is a summer proposition only. Both run warm rather than breathable in their leather forms, which is at least useful in winter.

Neither shoe is generous. The adidas Samba OG fits true to size with a medium width overall, but the toebox measures narrow, and anyone with a broad forefoot will feel it immediately — this is the single most common complaint about the shoe. The Onitsuka Tiger Mexico 66 is built on an even slimmer last with a low volume through the midfoot, which is exactly why it looks so elegant and exactly why it does not suit everyone. If you have wide feet, try both in person and expect to be disappointed by at least one. If you have narrow feet, the Mexico 66 will feel tailored in a way very few mass-market trainers do.

The adidas Samba OG is the more versatile and more forgiving choice. It works with jeans, tailoring and gym kit, it comes in an enormous range of colourways, and its bulkier profile balances a wide-legged trouser better. The Onitsuka Tiger Mexico 66 is the sharper, more considered option: slimmer, more distinctive, and the better partner for slim trousers, skirts and anything where a chunky toe would look wrong. The Mexico 66 also carries less saturation — the Samba has been so ubiquitous in Europe for so long that several style guides now publish lists of alternatives to it, which tells you everything about where it sits on the adoption curve.

Buy the adidas Samba OG if you want one flat trainer that goes with everything, lasts for years, and is easy to find in your size in any European city. Accept the slippery sole and the narrow toe. Buy the Onitsuka Tiger Mexico 66 if you want something slimmer and less common, you have narrow feet, and you are buying on silhouette rather than on durability. If neither fits, the adidas Handball Spezial offers the same terrace shape with a suede upper and a roomier feel, the PUMA Palermo covers similar ground from a different heritage, and the ASICS GEL-Kayano 14 is the answer if you eventually admit you want cushioning.
