Based on the shoe size data from 190+ brands, we were able to compare how Asics sizing scheme measures across the industry.
Verdict: Asics runs about a full US size big in men’s sizes and requires sizing down from most brands. Women’s models run true to size or half-a-size big.
To make things less complicated, we strongly advise measuring your foot length first. Then you can consult the chart below to find out the best-fitting Asics size for you.

How Asics shoes fit
Some models like Asics Gel Lyte sneakers have a more tapered toebox, so people with wide feet may want to consider the wider option.
Most of the performance-oriented race shoes from Asics will also fit snug and small. So, it is also recommended to check the information on a specific model that you’re interested in. You can find the size and fit recommendations on each product page on our website.
Asics has wide options
While the brand isn’t as generous with its widths variations as New Balance, it offers around 10% of its footwear in Wide options and 15% in Extra Wide.
Asics shoe widths for men and women
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:
- toes sticking out or rolling over the sole edge
- uncomfortable stretching of the upper material
If measuring your foot length is not an option right now, find a shoe from any brand that fits you well. The tool below will help you convert to Asics size.
