Diadora

It depends on the model. Diadora 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 Diadora 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 Diadora 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 Diadora 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.

Diadora is an Italian sportswear brand founded in 1948, known for heritage athletic footwear, particularly tennis shoes and running sneakers. The brand combines Italian craftsmanship with sports performance.

Diadora shoes generally fit true to size with a classic athletic fit. Heritage models may have a slightly narrower European fit compared to American sportswear brands.

Order your normal athletic shoe size for Diadora. If you have wider feet, consider going up half a size for comfort, especially in heritage models.
