Try our Size Advisor. All you need to do is enter your current shoe size in any of your favorite brands and it converts it to Atoms' sizes.

If you have trouble deciding size, please reach out to our support team on support@atoms.com.

Normally we send out three pairs of shoes to first time customers in quarter size increments so we can bring the in-store shopping experience to your living room and ensure you get your perfect fit hence the quarter sizing. We have temporarily stopped that because of COVID19. In the mean time, our Size Advisor should give you a great experience without the need to return extra shoes.

If you would like to try other sizes, please go ahead and order them - you can return the ones that don't work.

Ideally, you should have a 1/4 of an inch or about most of your thumb nail between your longest toe and the inside of the shoe for it to be a perfect fit. Your Atoms won't stretch much over time, so how they feel on day 1 is how they’ll feel on day 100.
