Most ASICS lifestyle sneakers fit true to size, so buy your usual US sneaker size. The Gel-1130 and Gel-Kayano 14 are the roomiest. The GT-2160, Gel-NYC and Gel-Kayano 20 are snug through the forefoot, so wide feet go half a size up, and the Gel-Lyte III and Gel-Nimbus 10.1 run small enough that most people go half up.

ASICS size chart (US, UK, EU and cm)

ASICS lifestyle sneakers are unisex and labelled in US men's sizes, with the women's size alongside. Measure your foot, find your true size below, then apply the model advice further down.

Source: official ASICS men's and unisex shoe size chart (asics.com/nz size guide). ASICS's size and fit guide describes the cm figure as your foot length, measured heel to longest toe. Other regional ASICS charts differ by a quarter centimetre around US 7 to 7.5.

Do ASICS run true to size?

Mostly, yes. Sneakerjagers' ASICS guide says ASICS sneakers generally fit true to size, and Mr Porter lists the Gel-NYC and Gel-Kayano 20 as true to size. The differences between models are about width and toe room, not length.

Some people still find ASICS a touch snug. Captain Creps says ASICS feel tighter than Nike and suggests half a size up from your Nike size. Sneakerlens disagrees for the Gel-Kayano 14, saying it matches the Nike Dunk size for size. Our advice: start from your usual US size, and go half up only if you have wide feet, sit between sizes, or the model below runs small.

ASICS sizing by model

Model notes and where sources disagree

• Gel-Kayano 14: Sneakerjagers, Sneakerlens and Solefeed all say true to size. Solefeed describes it as long but narrow, with a narrower toe box than the Gel-1130, so wide feet should go half up. Fascinate's staff review suggests half up for everyone, which is the outlier.
• Gel-1130: Solefeed calls it the widest ASICS retro runner and says true to size, and Hibbett says it's the more forgiving pick for wide feet. Zappos reviewers rated it 83% true to size. Only very wide feet need half up.
• Gel-NYC: Sneakerjagers, RunRepeat and Mr Porter say true to size, and RunRepeat measured a standard D width with room to move. Solefeed notes a low toe box, so wide feet go half up.
• GT-2160: Hibbett says it fits true to size but is notorious for a snug fit, and Solefeed calls it the narrowest of the 1130, Kayano 14 and 2160 trio. Wide feet: half up, or choose the Gel-1130 instead.
• Gel-Kayano 20 and Gel-Nimbus 10.1: Solefeed says the Kayano 20 is true to size with a snug forefoot, and that the Nimbus 10.1 runs about half a size small. If you're unsure on the Nimbus 10.1, take the half size up.
• Gel-Lyte III: Sneakerjagers and Captain Creps both say it runs tight and recommend half a size up.

ASICS widths

ASICS's width guide says the standard width is D for men's and unisex shoes and B for women's, with 2E (wide) and 4E (extra wide) fittings on some models. The box and label only show the width when it isn't standard, so a pair with no width letter is a standard fit. For wide feet in a lifestyle model, sizing up half a size or picking a roomier model like the Gel-1130 is the practical fix.

Women's ASICS sizing

On ASICS's official chart, US women's is exactly 1.5 sizes above US men's, the same gap as Nike and New Balance. A men's 7 is a women's 8.5, and a men's 8 is a women's 9.5. Mr Porter notes that ASICS packaging shows both men's and women's sizes.

So if you're a women's 9, buy a unisex 7.5 in true-to-size models like the Gel-Kayano 14 or Gel-1130, and an 8 in the Gel-Lyte III. Women's pairs such as the Gel-Kayano 14 White Midnight (W) follow the same model advice.

ASICS vs Nike and New Balance sizing

• Jordan 1 and Nike Dunk: both true to size. Start from that US size, then apply the model advice above. Sneakerlens says the Gel-Kayano 14 matches the Dunk size for size.
• Nike Air Force 1: runs big, so if you sized down in AF1s, your ASICS size is usually half a size above your AF1 size.
• New Balance: both brands use the same 1.5 men's-to-women's gap. The Gel-Kayano 14 and the New Balance 2002R and 1906R all fit true to size, so most people take the same US size in each. See our New Balance size guide.

How to measure your foot

1. Put a sheet of paper on a hard floor against a wall.
2. Stand on it with your heel against the wall, wearing the socks you usually wear.
3. Mark the tip of your longest toe and measure from the wall in centimetres.
4. Measure both feet and use the longer one.
5. Find that length in the chart, then apply the model advice above.

Measure later in the day, when your feet are at their largest. If you fall between two sizes, take the larger one.

ASICS sizing FAQ

Do ASICS run small?

Most ASICS lifestyle sneakers fit true to size, so buy your usual US size. A few run small: go half a size up in the Gel-Lyte III and Gel-Nimbus 10.1, and half up in the GT-2160, Gel-NYC or Gel-Kayano 20 if you have wide feet.

Should I size up in ASICS Gel-Kayano 14?

Only if you have wide feet. The Gel-Kayano 14 fits true to size in length but the toe box is slightly narrow, so wide feet go half a size up. Regular and narrow feet should stay in their usual size.

Which ASICS is best for wide feet?

The Gel-1130. It's the roomiest of the ASICS retro runners and fits true to size even for most wide feet. The GT-2160 is the snuggest, so wide feet should go half a size up in that one.

How do I convert ASICS men's to women's sizes?

Add 1.5 to the US men's size. On ASICS's official chart a men's 7 is a women's 8.5 and a men's 8 is a women's 9.5. To go from women's to men's, subtract 1.5.

Are ASICS the same size as Nike?

Mostly. ASICS uses the same US and UK numbers as Nike, so start from your true Nike size, such as your Jordan 1 or Dunk size. Some people find ASICS a touch snugger, so go half up if you're between sizes or have wide feet.
