SIZING CHART

Most people have at least a quarter size difference between their left and right feet. To find the perfect fit, Atoms offers the Quarter Size Experience. We will send you three pairs of Atoms in quarter-size increments based off your standard shoe size. You can 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. Send back the remaining shoes within 7 days using the included box and shipping label.

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.

QUARTER SIZE EXPERIENCE

To find the perfect fit, Atoms offers the Quarter Size Experience. 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.
