How to select the perfect Atoms shoe size for me?
There should be a ¼ to ⅓ of an inch distance between your longest toe and the front of the shoe (about a half a thumb nail). Your Atoms won't stretch much over time, so how they feel on day 1 is how they’ll feel on day 100.
If you need help with finding your size, please email us on support@atoms.com.
You can also try our Fit Finder.
Enter your current shoe size in any brand you use now and it converts it to Atoms' sizes.
This chart with international shoe size conversions might help too.
This chart is also available in Japanese, Chinese Traditional, and Chinese Simplified.
Kids sizes can be found here.
If you would like to try multiple sizes, please go ahead and order them - you can return the ones that don't work.
Note - With the onset of the pandemic, we had to discontinue our "split size" offer where you can mix and match sizes for each foot. We're sad to let that feature go, but if there is enough demand for it, we may bring it back.
