Onitsuka Tiger

It depends on the model. Onitsuka Tiger fit varies between styles, so a single verdict for the whole brand would be misleading, and we only publish a fit verdict where we have measured one. The dependable way to answer it for the pair you are buying is to work from a shoe you already own and know fits: enter it above and we will tell you which Onitsuka Tiger size matches it.

Start from a shoe you already own that fits, rather than from your usual number. Enter it above and we will convert through foot length to the matching Onitsuka Tiger size, which is the part that carries across brands. The EU to US offset is not the same for every brand, so a rule of thumb learned elsewhere will not hold here.

Not directly, because a size label means whatever the brand decides it means. A Nike 42 and an Adidas 42 are cut for different foot lengths, and so is a Onitsuka Tiger 42. Foot length is the common unit, which is why our comparison works from the measurements behind each brands chart rather than from the number printed on the box.

Onitsuka Tiger is a Japanese heritage footwear brand founded in 1949 by Kihachiro Onitsuka in Kobe, Japan. The predecessor to ASICS, the brand is renowned for the iconic Mexico 66 sneaker and retro-athletic designs that blend Japanese craftsmanship with vintage style.

Onitsuka Tiger shoes run small and narrow compared to mainstream athletic brands like Nike and Adidas. The Mexico 66 fits true to size for average feet but is notably narrow. If you wear Nike US 10, try Onitsuka Tiger US 10.5 or even US 11.

Size up half to one full size from your Nike/Adidas size. For the Mexico 66 and Serrano, the narrow toe box is the main concern - go up if you have wider feet. Leather models break in and soften within 1-2 weeks. Japan CM sizing is the most accurate reference.
