How Asics shoes fit

Asics is predictable in the sizing of its various shoe types and models. You can expect an accommodating fit in any of its acclaimed series like the Gel Kayano, Nimbus, and Cumulus.

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.
