Frequently Asked Questions About ASICS Sizing

It depends on the model. ASICS 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 ASICS 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 ASICS 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 ASICS 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.
