Onitsuka Tiger Size Chart India: Mexico 66 Fit Guide
The Mexico 66 carries its low profile, narrow last straight from its 1960s athletic shoe origins, and that narrow build is why Onitsuka Tiger has a reputation for running small compared to Nike or adidas in the same number. This guide gives you the conversion chart and the adjustment most Indian buyers need.

The one rule that fixes most sizing mistakes
If you wear a Nike or adidas US size, go half a size up on the Mexico 66, a full size up if you have wide feet. The narrow, pointed toe box inherited from the shoe's original design is the main reason for this, more than a general length issue.

Mexico 66: fit notes
Runs small and narrow compared to Nike or adidas. The low profile last and pointed toe box are original to the 1960s design and have not changed. True to size works for narrow feet who are comfortable with a snug, low volume fit. Everyone else, especially wide feet, should size up half to a full size from their usual sneaker number.

India specific fit considerations
Foot width. Indian feet running wider than the Mexico 66's narrow pointed toe box is the single biggest reason for sizing complaints. If you know your foot is on the wider side, plan for the full size up rather than starting with half and hoping it is enough.
Converting from a familiar brand. Since most Indian buyers know their Nike or adidas size and not their Onitsuka Tiger size directly, treat that familiar number as a starting point to size up from, not a direct match.
Every pair from the Onitsuka Tiger collection at Kicks Machine is inspected in house before it ships, size stamp checked against the box label.
Care tip: canvas and suede uppers need the right fit to last
An undersized Mexico 66 stretches the canvas or suede unevenly at the narrow toe box, creating permanent stress points faster than normal wear would. Getting the size up adjustment right the first time protects the upper longer. Our sneaker care collection has cleaning products suited to canvas and suede.
