Collection: Is a UK Size 6 an EU 39?

As you can imagine this is a question I get asked a lot and I'll try my best to answer it here. The short answer is that it could be either and is completely dependent on whether manufacturers decide to round their sizes up or down. Most commonly a UK 6 will be referred to as an EU 39.

The majority of the shoes available in the UK are made in EU sizes. This is then converted into the equivalent UK size. The issue here is that these sizing systems aren't directly comparable. The exact dimensions of a UK 6 (measured by foot length) as defined by ISO 19407 is 245.53mm, whereas an EU 39 is 246.6mm. As you can see, a UK 6 is actually slightly smaller than an EU 39.

Additionally, to accommodate a foot length of 245.53mm (UK 6), the shoes internal length (or length of the last) would need to be between 253-265mm. The individual manufacturer will use this information to decide upon the appropriate size and/or conversion to use that will best suit their customer.
