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. Trace your foot on paper and measure from heel to longest toe.
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.
