The size guide says to measure your foot heel to big toe and compare with the chart, so lengths are foot lengths. Values kept as printed, including the inch value for US 10 printed as '11/ 1/6' (an evident typo; the cm value is unaffected). Women's equivalents are 'approx.' for US 4-6 and empty from US 13 up. The inch and cm rows do not always agree (e.g. US 4: 8 11/16 in, 23.2 cm).

What we could not verify

  • reef.co.uk could not be opened (it showed a bot check) and was not used.
  • reef.eu calls itself the official Reef webshop but its terms name a distributor (Brandfusion Holland BV) and reef.com does not link to it, so it is not listed as a regional shop.
  • No REEF shopping app or loyalty programme page is linked from reef.com.
  • outlet points to the men's sale section (women's and kids' sale sections also exist).
  • REEF gives separate charts for sandals and shoes, and their sizes do not line up exactly (e.g. a men's US 8 is 26 cm in shoes but 26.4 cm in sandals).
  • The size guide gives no width options.

Questions

Which length does REEF's size chart list?

REEF's charts give these lengths — CM: size in cm, given by the brand as 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 REEF 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. REEF itself advises: Measure your feet at the end of the day, from the tip of the big toe to the back of the heel, and compare with the chart.

When should I not compare REEF 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 REEF's chart last checked?

On 2026-10-24, against REEF'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.
