Short answer
The Onitsuka Tiger Mexico 66 provides a snug fit that honors its heritage as a 1960s track runner. For most users, the model runs true to size (TTS) in length, but the narrow toe box and slim silhouette necessitate careful consideration for those with wide feet.

Fit Notes
- Adidas Samba (OG)
- Both models utilize a narrow retro profile, but the Mexico 66 is more flexible and uses unlined leather that functions like a membrane. If you typically size up in the Samba just to gain width relief from its rigid structure, you may find your true length works in the Mexico 66 as the material allows for more natural lateral expansion.
- Nike Air Force 1 (AF1)
- The AF1 runs notoriously long and wide with a high-volume last. In contrast, the Mexico 66 is significantly more streamlined and narrow. To avoid a painfully tight experience, AF1 wearers should size up by a minimum of a half size to account for the Tiger's lack of internal volume.
- Nike Dunk Low
- Dunk Lows feature substantially more internal padding and a wider forefoot. Because the Mexico 66 uses a slim Asian last, moving up a half size is necessary to provide enough length to clear the width requirements of a standard Nike foot profile.
- New Balance 574
- New Balance 574 models are characterized by high internal volume and a wider base. The Mexico 66's low-slung, narrow design offers much less space, requiring a half-size increase for those accustomed to the roomy fit of standard New Balance silhouettes.
Sizing FAQ
Does the Onitsuka Tiger Mexico 66 run true to size?
Yes, approximately 79% of users report that the Mexico 66 fits true to size (TTS) in terms of length. However, it is built on a narrow Asian last with a slim silhouette. While the length is accurate, users with wider-than-average feet often find it necessary to size up half a size to alleviate lateral compression.
Is the Onitsuka Tiger Mexico 66 good for wide feet?
While built on a narrow last, the Mexico 66 is more accommodating than other retro runners because of its thin, unlined leather upper which can expand by nearly half a size during the break-in period. Users with D or E width feet can often wear their standard size after break-in, but those with EE or wider profiles are advised to size up by half to a full size.
How is the arch support on the Onitsuka Tiger Mexico 66?
The arch support is minimal, as the shoe is a 'minimalist' silhouette with a thin sole. It contains a small internal EVA or Ortholite wedge to provide baseline contact. It is often rated as comfortable for users with flat feet, but those with high arches may find it unsupportive for extended walking and might require third-party insoles.
