Size guide

How to find your size?

The best way to ensure your OOFOS fit perfectly is to measure the length of your feet and use the chart above to determine your size. To get your foot length, trace your foot on a piece of paper and measure from the heel to the tip of the longest toe. If your measurement falls between numbers on the chart, simply round up.

Can’t measure your feet?

OOFOS runs true to size with most other footwear brands. If you are a whole size in another brand, order that same whole size in OOFOS.
