Black Friday - best deals from 52 stores Based on the data from 40+ brands in our database, we found that ASICS shoe sizes are generally consistent with the industry average.
But if you want to keep the chance of error to a minimum, we strongly advise measuring your foot length first. Then you can find the best-fitting ASICS size for you.
ASICS men's and women's size chart
How ASICS shoes fit
When it comes to ASICS running shoes, the brand's sizing is quite predictable. You can expect an accommodating true-to-size fit in its acclaimed running shoe series like the Gel Kayano, Nimbus, and Cumulus, among others. But if you are getting a competition-ready shoe (i.e. the Metaspeed), expect a more snug and sock-like fit.
We also found that ASICS tennis shoes tend to have a predictable fit with an extra secure midfoot hold for stability.
However, fit and sizing can get tricky in the brand's lifestyle category. The variety of styles and shapes among ASICS sneakers calls for specific recommendations for each model.
But we are here to ease your research by offering in-depth lab reviews which include toebox width and heel-to-toe length measurements of each ASICS shoe. Dig into the category of your interest to find more information.
Unisex ASICS shoes
Quite a few casual sneakers, running shoes, and other types of athletic footwear from ASICS are offered as unisex models because of their gender-neutral design.
In this case, women's US size would be 1.5 times bigger than men's. For example, ladies who need a women's US size 8 will need to get a men's US size 6.5 for the correct fit.
ASICS shoes have wide options
While the brand isn’t as generous with its width variations as New Balance, most of its popular athletic shoes are offered in extended width options like Wide and Extra Wide.
ASICS shoe widths for men and women:
| Width | Men | Women |
| 2A | - | Narrow |
| B | Narrow | Standard |
| D | Standard | Wide |
| 2E | Wide | Extra Wide |
| 4E | Extra Wide | - |
Wider widths are recommended for people with naturally wider feet or foot conditions like bunions. Here are some of the visual signs that you need a wider shoe:
- bulging
- toes sticking out or rolling over the sole edge
- uncomfortable stretching of the upper material
If wide options are not available, you might as well opt for ASICS shoes with wider-than-average toebox dimensions which provide a notably roomier fit.
ASICS shoe sizing vs. Nike and other brands
ASICS’ sizing scheme primarily corresponds to that of Adidas, Brooks, and New Balance. However, there tends to be a half-size difference in women's sizes with Nike and Saucony.
| Shoe length (mm) | ASICS | Nike | New Balance | Brooks | Saucony | Adidas |
| Men's US sizes | ||||||
| 270 | 9 | 9 | 9 | 9 | 9 | 9 |
| 280 | 10 | 10 | 10 | 10 | 10 | 10 |
| 290 | 11.5 | 11 | 11 | 11 | 11 | 11 |
| Women's US sizes | ||||||
| 230 | 6 | 6.5 | 6 | 6 | 6.5 | 6 |
| 240 | 7 | 7.5 | 7 | 7 | 7.5 | 7 |
| 250 | 8 | 8.5 | 8 | 8 | 8.5 | 8 |
