What size ASICS should I buy? The ultimate guide
• Nando de Voer

Choosing the right size for ASICS sneakers is more important than many people think. Whether you’re rocking the ASICS GEL-NYC or adding the GEL-Kayano to your rotation: a wrong fit can ruin both your look and comfort. In this blog, we explain exactly how ASICS sneakers fit, which models are tight, and what to watch out for when making your purchase.

Which ASICS size should I buy?

Most ASICS sneakers run small. So it’s best to go half a size up from your normal shoe size. This prevents pinched toes and ensures extra comfort, especially with models that have a snug fit like the GEL-Kayano or the GEL-Nimbus.


How do I know for sure which size I need?

First, try measuring your feet in centimeters. Measure them in the evening when they are at their largest. Then use the ASICS size chart and round up if you’re between two sizes.

Tip from Snrkickz: do you wear your sneakers with thick socks or have wide feet? Then always go for half a size larger than usual. ASICS sneakers are known for their design, which means: snug, firm, and supportive. Nice, but you still want room to move.

Do ASICS run large or small?

ASICS sneakers run smaller than average. The fit is generally narrow and firm. This is because many models were developed as running shoes. Even the GEL-NYC – a popular lifestyle sneaker – has a more compact fit compared to, for example, New Balance.


Which ASICS models fit tight?

Some models are known to be a bit narrower or stiffer:

ASICS GEL-Kayano → firm heel construction

ASICS GEL-Nimbus → soft cushioning but compact upper

ASICS GEL-1130 → retro tech look, but slim build

ASICS GEL-NYC → slightly narrow toebox

These sneakers look clean but need a bit more room than your normal size.


Size advice by foot type

Wide feet → Always go half to a full size larger

Narrow feet → You can try true-to-size unless you wear extra thick socks

High instep → Choose a model with stretch material or a wider fit

Fit comparison with other brands

ASICS vs. Nike → ASICS usually runs smaller

ASICS vs. New Balance → ASICS is more technical and tighter

ASICS vs. Salomon → similar fit, but Salomon often feels a bit softer

 

What if I’m unsure between two sizes?

When in doubt: always choose the larger size. ASICS sneakers don’t stretch much after breaking in, especially if they have a lot of reinforcement in the heel or toe. Comfort comes first, and a little extra room is better than tightness.

 

What you need to know when ordering!

ASICS sneakers are popular for their tech look and solid construction, but they often run a bit smaller than you’re used to. By buying just a bit larger, you avoid disappointment and enjoy both style and comfort. Whether you go for a GEL-Kayano, GEL-1130, or the popular GEL-NYC – with this guide, you’ll pick the right size right the first time.
