Choosing the correct ASICS shoe size is essential for comfort, support, and performance. A reliable ASICS shoe size chart helps you compare US, UK, and EU sizes while matching them to your foot length for a more accurate fit.
Whether you’re buying GEL-Kayano, GEL-Nimbus, GEL-1130, GT-2000, NOVABLAST, or another ASICS model, this guide will help you measure your feet correctly, understand ASICS sizing, and choose the best fit for running, walking, training, or everyday wear.
ASICS Shoe Size Chart
ASICS uses standard US sizing with corresponding UK and EU conversions. Most ASICS shoes fit true to size, but the brand recommends selecting your size based on foot length in centimeters whenever possible. Many ASICS models are also available in Narrow, Standard, Wide (2E), and Extra Wide (4E) options, depending on the style.
| US (Men) | UK | EU |
|---|---|---|
| 6 | 5 | 39 |
| 7 | 6 | 40 |
| 8 | 7 | 41.5 |
| 9 | 8 | 42.5 |
| 10 | 9 | 44 |
| 11 | 10 | 45 |
Sizing may vary slightly between ASICS collections. Always refer to the official ASICS size guide for the specific model you’re purchasing.
Foot Length to ASICS Shoe Size
Foot length is the most accurate way to choose ASICS shoes. Measure both feet while standing and use the larger measurement when comparing it with the official size chart.

| 24.5 | 9.65 | 6 |
| 25.3 | 9.96 | 7 |

How to Measure Your Feet
Wear the socks you normally use with your ASICS shoes and stand on a sheet of paper placed against a wall. Mark the back of your heel and the tip of your longest toe, then measure the distance between the two marks.
Measure both feet because one foot is often slightly larger than the other. Use the larger measurement when choosing your shoe size. For the most accurate results, measure your feet in the evening when they naturally expand after a full day of activity.
How Should ASICS Shoes Fit?
ASICS recommends leaving about ½ inch (12–13 mm) of space between your longest toe and the front of the shoe. Your heel should feel secure while your toes have enough room to spread naturally during walking or running.
If the shoe feels tight across the forefoot, choose a Wide (2E) or Extra Wide (4E) version instead of automatically buying a longer size. ASICS offers multiple width options in many of its most popular running shoes.
Buying Tips
- Measure both feet before ordering.
- Compare your measurements with the official ASICS size chart.
- Wear your regular running socks while measuring.
- Leave about a thumb’s width of toe space.
- Choose Wide or Extra Wide models if needed.
- Read customer reviews for model-specific sizing.
- Buy from authorized ASICS retailers with an easy return policy.
Common ASICS Sizing Mistakes
One common mistake is choosing the same size as casual shoes without considering running shoe fit. Your feet naturally expand during exercise, so extra toe room improves comfort on longer runs.
Another mistake is buying a longer shoe when the real issue is width. If your ASICS shoes feel tight across the forefoot, selecting the proper width usually provides a better fit than increasing the shoe length.
Conclusion
A properly fitted pair of ASICS shoes provides the cushioning, stability, and comfort needed for every workout or daily activity. Measuring your feet and comparing them with the official ASICS size chart is the best way to choose the correct size before purchasing.
Because sizing and width availability vary between ASICS collections, always check the official size guide for the specific model you’re buying. The right fit helps you stay comfortable whether you’re running a marathon, walking every day, or wearing ASICS casually.
