Onitsuka Tiger Mexico 66 gray sneakers: a low-profile, leather-lined retro trainer

Pros

• · Multiple buyer reviews report the Mexico 66 generally runs true to size.
• · Buyers describe the shoe as stylish and versatile for casual and smart-casual wear.
• · Listing material: breathable leather and synthetic upper with a real leather lining, Solyte and EVA midsole, rubber outsole, described as lightweight and flexible.
• · Listed in sizes 36–45 including half sizes, with the size sheet running 35 through 45.

Cons

• · Some pairs develop a squeaking insole, which Onitsuka Tiger reportedly acknowledged as a manufacturing defect caused by improper cementing of the insole.
• · A long-term owner reports poor sole durability on the all-leather Mexico 66.
• · Reviewers describe the forefoot as narrow and the fit as shape-sensitive, with a break-in period before the upper molds to the foot.
• · A Chinese-language Serrano owner review notes the rubber outsole is not very slip-resistant and advises caution in rain, and worries the upper could crack with long-term wear.
• · Buyers rate it for casual wear rather than real athletic activity.

Fit notes

Multiple buyer reviews put the Mexico 66 true to size; reviewers comparing to Nike running shoes suggest going down about half a size (a 7.5 in Nike Air Max translating to a 7 here). The forefoot is narrow, so allow a break-in. The listing spans 36–45 with half sizes.

Buy if

You want a slim, low-profile sneaker for casual and smart-casual outfits, prefer a leather lining and a thin Solyte/EVA sole underfoot, and need a broad size run — the listing offers 36–45 with half sizes.

Skip if

You need shoes for running, the gym, or real athletic activity, want cushioning or grip on wet and greasy ground, or have a wide forefoot that rarely suits a narrow, shape-sensitive last.
