Onitsuka Tiger Mexico 66 in brown: a lightweight, low-profile leather sneaker

Pros

• · Buyers report a generally true-to-size fit, including one reviewer who normally wears a US 13 and found that size comfortable.
• · Reviewers describe no break-in period, citing pliable leather uppers and thin flexible soles that feel comfortable out of the box.
• · Long-term owners report durable uppers, with one all-leather pair still in use after roughly seven years.
• · Catalog construction: breathable leather and synthetic upper, leather lining, Solyte and EVA midsole, rubber outsole, with half sizes listed across the size range.

Cons

• · Buyers report the thin soles wear out relatively quickly, with regular pairs lasting about a year of everyday wear.
• · One buyer reported significant quality issues after 2–3 weeks, specifically excessive leather creasing.
• · The Mexico 66 line is reported to have a known squeaking-insole defect on some pairs.
• · The thin, low-cushion sole is reported to feel uncomfortable for buyers used to more heavily cushioned shoes.

Fit notes

Buyers report the Mexico 66 generally runs true to size, though the forefoot is narrow and the break-in is shape-sensitive. For wide feet, buyers advise against sizing up — the brand's wide version adds roughly 4–6mm at the ball instead. The Mexico 66 SD runs narrower at the toe and longer overall.

Buy if

Buy for casual, low-mileage wear if you want a flat, lightweight sneaker in your usual size and accept that the thin outsole is the part that goes first. Suits buyers who treat the sole as replaceable rather than expecting years of daily use.

Skip if

Skip if you need underfoot cushioning or cover long distances on hard pavement, and skip for wet weather — the catalog cites buyer feedback that grip is not strong, with advice to avoid rain. Also skip if a reported squeaking-insole defect would be a dealbreaker.
