Merrell footwear uses the Mondo sizing system, where each whole size is equivalent to exactly 1cm in length. To ensure the best fit we recommend you:
● Buy the same size as last time, if you have owned Merrell footwear before. Their sizing has not changed.
● Shop using Mondo sizes.
● Follow our "How to Measure Your Mondo Size" advice and video lower down this page.
● Shop using US sizes.
Correct as shown below.
UK & EU Sizes
We recommend you do not buy using UK or EU sizes because Merrell have screwed up! There is no difference between men's and women's sizes and the table below contains other Merrell mistakes. If you prefer to shop using UK or EU sizes, please refer to the "Absolute" columns which show the correct size conversions.
On Our Website.....
On our website we use Merrell 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 Mondo Size
The Mondopoint size of a shoe 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.
