Onitsuka Tiger Mexico 66 Orange Sneakers: Thin-Sole Leather Trainers With Almost No Break-In

Pros

• · Little to no break-in reported: pliable leather uppers and thin, flexible soles, with blister-free wear described over multi-mile days.
• · Breathable leather and synthetic upper with a leather lining over a lightweight EVA/Solyte midsole, per the catalog.
• · Listed across a broad size run from 36 to 45 with half sizes, and the line carries many colorways.

Cons

• · Narrow, pointy last with almost no forefoot foam — minimal cushioning, kept in the line for its heritage look rather than comfort.
• · Thin rubber outsole gives limited grip; the listing cites buyer feedback that it is not slip-resistant and advises against wearing it in rain.
• · The Serrano fit is described as true to size but slightly narrow, tight for wider feet.

Fit notes

Reports split: some buyers take their usual size, others a half or full size down. One reviewer who wears a 13 in adidas Samba and Nike Flyknit found a 12.5 perfect, even with wider feet. The Serrano runs true to size but slightly narrow. Listed sizes 36–45, half sizes included.

Buy if

You want a lightweight, low-profile leather sneaker for dry-weather everyday wear, your feet are average or narrow, and you accept a thin sole with little forefoot cushioning. Buyers report almost no break-in period.

Skip if

You need forefoot cushioning, room for a wide forefoot, or traction on wet pavement. The last is described as narrow and pointy, and the thin outsole is noted as not slip-resistant, so rain wear is something buyers advise against.
