How to find your size? Trace your foot and measure from the heel to the tip of the longest toe. If you land between sizes, round up.
OOFOS runs true to size with most other footwear brands. If you are a whole size in another brand, order that same whole size. If you are a half size, women should order up and men should order down for slides, sandals, and clogs.
