Convert your OOFOS size to another brand
What we could not verify
- Category set to sandals: the site leads with "Recovery Footwear", recovery sandals and slides.
- origin US: oofos.com is the US shop (US-only shipping, EST support hours) and calls the other sites international expansion; no HQ address is printed on the pages opened.
- The FAQ link goes to a help centre outside the official domains, so help points to the shipping & returns page.
- Regional sites come from the oofos.com country selector and its International Partners page; several are run by distribution partners.
- OOFOS has no standalone size chart page; the charts come from the Size guide pop-up that appears on its product pages, so there is no size guide link.
- No kids' chart is given in the size guide.
Questions
Which length does OOFOS's size chart list?
OOFOS's charts give these lengths — Mondopoint: 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 OOFOS 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. OOFOS itself advises: Measure your foot from heel to the tip of the longest toe and use the chart; if you fall between sizes, round up. OOFOS says it runs true to size: if you wear a whole size in another brand, order the same whole size. For unisex slides, sandals and clogs, if you are a half size in another brand, women should go a size up and men a size down.
When should I not compare OOFOS 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.
When was OOFOS's chart last checked?
On 2026-10-24, against OOFOS'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.
