Sandals & slippers: half sizes

OluKai sandals and slippers come in whole sizes only.

If you wear a half size, OluKai says sizing up to the next whole size usually fits best — for example, if you wear a 10½ in shoes, a size 11 will likely fit you best in OluKai sandals and slippers.

Shoes

Many OluKai shoes and slip-ons come in half sizes. Start with your usual size, and use the chart below to check your foot length.

Between sizes? Size up if you wear thick socks or orthotics, or you're on your feet all day. Choose the smaller size if you like a snug, athletic fit.

Model exceptions

Moloa slip-on shoe: from our fitting experience, the Moloa runs big. Consider a half size smaller than your usual size.

Moloa Hulu slipper: also runs big. It comes in whole sizes only, so if you wear a half size, choose the next whole size down — the opposite of OluKai’s usual slipper advice.

How to measure

Stand on a sheet of paper, with your weight on that foot.
Mark the back of your heel and the tip of your longest toe.
Measure between the marks in inches or centimeters.
Measure both feet and use the longer one.
Measure later in the day, when feet are at their largest, wearing the socks you’ll wear with the shoes.

Need help? We measure every customer with a Brannock device at our Kettering store. Stop in for a fitting, or call us at 937.298.1801 and we’ll help you choose. Ready to shop? Shop all OluKai →
