As printed by the brand. The length listed for 12 does not fit the rest of the chart, so the converter does not match on it.

Brand columns: Women's, cm, in, Men's. The pop-up does not say whether cm/in is foot or shoe length. The Men's column is left empty where the brand leaves it empty. Values kept exactly as printed, including US 12 = 28.73 cm / 27.7 in (an evident typo: the inch value is a centimetre-sized number and the cm value jumps 1.8 cm from size 11).

What OluKai says about fit

Sandals and slippers come in whole sizes only; if you wear a half size in shoes, sizing up (e.g. 10.5 to 11) usually fits best. (source)
Each product page has a Fit Guide showing how that style runs in size, width and arch; narrow or wide feet may affect fit. (source)

Questions

Which length does OluKai's size chart list?

OluKai's charts give these lengths — CM: measured foot length. A measured foot length and a size in cm are about 8 mm apart for the same size, so compare your own foot length only with a column on the same scale.

Does the official chart tell me how a OluKai shoe will fit?

Only in part. The chart gives the length each size is meant for; how a particular model fits also depends on its last, width and materials, which the chart does not show. OluKai itself advises: Sandals and slippers come in whole sizes only; if you wear a half size in shoes, sizing up (e.g. 10.5 to 11) usually fits best. Each product page has a Fit Guide showing how that style runs in size, width and arch; narrow or wide feet may affect fit.

When should I not compare OluKai sizes with another brand?

When the two charts list different lengths. A measured foot length and a size in cm are about 8 mm apart, and the length of a foot is not the inside length of a shoe, so such a match can be half a size or more off. The converter matches only lengths on the same scale and lists the other brands separately. OluKai's chart does not say whether its lengths are foot or shoe lengths, so treat any match with another brand as approximate.

When was OluKai's chart last checked?

On 2026-10-24, against OluKai's official size guide linked under each chart. The date changes only when the chart is checked again against the official page or its numbers change, not when this page's layout or wording changes.
