Reef sandals and flip flops fit true to size straight out of the box.
Size conversions between the different worldwide measuring systems (Mondo, UK and US) are accurate and correct with just a few minor exceptions for some EU sizes. The column entitled "EU Absolute" is our calculation of the equivalent EU shoe size. We are convinced the "EU Absolute" column is correct because it is used by most other brands and because the sequence of sizes follows a consistent pattern. EU shoe sizes increase in 3.333mm increments - which is why, when presented to a single decimal point, they should always end with .0, .3 or .7 and never with .5.
On Our Website.....
On our website we use Reef sizes (even though they are not always correct) because these are what appear on the shoe boxes and the shoes themselves.

How to Measure Your Size
Go with your normal shoe size or, if you are usually between sizes, go to the larger end of your range. There is usually no need to buy bigger or smaller than your normal shoe size.
Most footwear is manufactured using the Mondopoint sizing system. 'Mondo' means 'world' and mondopoint is the global standard - which is very simple, making it nice'n' easy to choose the correct size footwear. The Mondopoint size is the length of the shoe's insole measured in cm. To work out your size, the best way is to look it up on a pair shoes which fit you well or to measure the length of the insole on your best fitting pair of shoes. Remove the insole and measure, using a steal measuring tape, from the extreme tip of the toe to the extreme tip of the heel. The measurement will ALWAYS be exact to the nearest 0.5cm. You will never get 30.2 or 28.8; it will always be 30.0 exactly. This is your mondo shoe or boot size. Checkout this video to have Adam explain it all in plain English. He is using a snowboard boot but the same principle applies to all footwear.
