Sizing chart

Atoms are available for men in all quarter sizes between 3.5 and 15. For women, Atoms are available in all quarter sizes between 5 and 16.5. All sizes are US based.

Home Try-On

To find the perfect fit, Atoms offers the Home Try-On. Here's how it works:

1. We will send you three pairs of Atoms in quarter-size increments based off your standard shoe size. (You only pay for one pair.)
2. Try on all three pairs and keep the individual shoes that fit best — for example, a size 7.75 for your right foot and a size 8 for your left.
3. Return the remaining shoes for free. A prepaid shipping label is included with your order.

JUST SEND ME ONE PAIR

If you are confident in your size and would only like to receive one pair of shoes, we are happy to do so.

Free shipping & returns within US

Atoms will accept returns made within 30 days of the date of purchase and issue a refund. Your Atoms come with a prepaid return label and a box for returns. Place the shoes in the box and seal it and attach the return label to the outside of the box. Then you can drop it off at any UPS location.

We offer free shipping on all orders within United States. You should expect to receive your order within 2-3 business days after it ships.

Same size pair

If both your feet are the same size, you should choose same size option.

Split size pair

If one of your feet is larger or smaller than the other, you should choose split size option. Most people have at-least a 1/4 size difference between their feet, and this is why we offer this option.
