Find your ASICS size fast (CM to EU/US)

Measuring in centimeters is most reliable, because US/UK sizes can vary by brand.

• In the afternoon, trace your foot from heel to longest toe on paper. Measure both feet and note the larger length.
• Add 0.5–1.0 cm of toe room for casual daily wear, 1.0–1.5 cm for running or intense sports.
• Use the official ASICS size chart to find your size based on CM and map it to EU/US. Unsure and have wide feet? Often choose half a size up.

Tip: measure wearing the socks you normally use with your sneakers.

Between sizes or want to fine-tune the fit? With insoles you can adjust cushioning and volume, especially helpful with half sizes.

Fit by model type

ASICS generally fits true to size, but fit differs by line. Lifestyle/retro models like the GEL-Lyte III and Kayano 14 often feel slightly narrower in the forefoot; many wear true to size, while wide feet may prefer half a size up. Performance running models such as GEL-Nimbus and GEL-Kayano usually fit normal with sufficient toe room for running (plan 1.0–1.5 cm extra). GEL-Quantum and some GEL-Kinsei versions can feel slimmer around the midfoot. Note WMNS/GS variants: these are often a bit narrower than unisex/men’s.

A popular lifestyle model is the ASICS GEL-NYC collection; it can feel a bit slimmer in the forefoot. For wide feet, half a size up is often nicer.

Looking for extra lockdown or better pressure distribution over your instep? With ASICS laces you can fine-tune the fit more precisely.

ASICS vs Nike: how do sizes compare?

Nike is known for a slim last; ASICS is typically a bit more consistent and true to size. In centimeters they’re often similar, but US sizes can differ by brand. Do you wear EU 42 in Nike, which equals about 26.5–27.0 cm? Choose the same CM in the ASICS chart. If you have wide feet or are used to Nike’s slim fit, going up half a size in ASICS can feel better.
