What is the difference between US and Euro Shoe Sizes?

Euro size numbers are also not the only thing that differentiates American and Europe-made shoes, for one, European shoes tend to be more narrow in the heel with a wide toe box allowing the heel to be held snug in place without scrunching the toes. Shoes made in the United States meanwhile have a deeper toe box and more cushion than their European counterparts. Most European brands also provide more arch support. These common generalizations however are not true for all American and European shoe brands with some of these firms following their own set of metrics. Compared to the European sizing, the US shoe sizing system could come in narrow, medium, wide, and extra-wide widths than how European sizing system shoes are.

Converting UK to US Shoe Size: How does it work?

Converting UK to US Shoe Size
The easiest way to convert your UK to US shoe size is to remember that numerical correspondent of UK sizes are smaller than its US shoe size counterpart.
For men, simply add a half-size (.5) to your existing UK shoe size. For example, a UK shoe size 6 is a US 6.5 measuring 9 ⅔ inches.
For children shoes. To get your US shoe size, also add a size to your current UK shoe size to get the US size. For example, a size 1 in UK children’s shoes, will be a US 1.5 which is 3 ⅞ inches.
For women, to get the US size equivalent of your UK shoe size, add two (2) sizes up to your existing UK size. In this case, a UK women’s shoe size 4.5 is a US 6.5 or 9 ⅙ inches.
The UK standard is considered to be the oldest used shoe sizing metric in the world, dating back to as early as 1324 when it was made the standard English shoe measurement by King Edward II.
The British shoe size standard is based on the measurement of the ‘shoe last’ which is typically made of wood, but could also be from other materials. This shoe frame measures 13 to 17 mm more than the natural shoe size from heel to toe.
Under the UK standard, there is the distinction between adult and children’s shoe sizes. Men and women also have specified measurements. This is different than the Paris point-based system which has a uniform standard for children’s and adults’ shoes.
The UK shoe size standard only considers the length of the foot, but not the width. Shoes then tend to have different width measurements depending on the ‘shoe last’ used by the brand.
Each size in UK shoe sizing has an 8.46 mm (or one-third of an inch) difference. The half-sizes (4.23 mm) difference were per pair were introduced in 1880 to ensure better fit.
Generally, the UK’s shoe sizing standard is also used in Australia. Other countries such as the US, China, Japan, and even other European countries like France also uses their own shoe size standard.
