EU shoe sizes are based on the Paris point system — 1 Paris point = ⅔ cm. So an EU 40 shoe has an inner length of approximately 40 × ⅔ = 26.7 cm. The system is used across continental Europe and has been adopted globally by many shoe brands.
EU sizing is gender-neutral — the same number refers to the same foot length for both men and women. EU 42 = men's US 8.5 = women's US 10. This neutrality makes EU sizing simpler for global brands.
Interesting fact: The EU size scale was proposed by the French Shoe Industries Association in the 20th century. The 'Paris point' (⅔ cm) was chosen because it bisects the difference between the older French and British shoe sizing increments, creating a convenient intermediate standard.
UK shoe sizes use a numbering system where size 0 corresponds to a child's foot of 4 inches (101.6 mm), with each size increment being ⅓ inch (8.47 mm). Adult UK sizes start around 3. The system predates metrication and remains the standard in Britain.
UK adult sizes run roughly 1–14 for men and 2–10 for women. UK sizes are approximately 0.5 lower than US men's sizes (UK 9 = US 9.5) and about 2 lower than women's US sizes (UK 6 = US 8). UK children's sizes continue into adults without a break.
Interesting fact: The Mondopoint international shoe sizing standard (ISO 9407) attempted to replace all regional systems with foot length in millimeters, but despite adoption by NATO for military footwear, it has not displaced local systems in retail.
Shoe sizes are not standardized internationally. EU sizes use Paris points (⅔ cm), US sizes use barleycorns (⅓ inch), and UK uses a similar scale with a different offset. US men's and women's sizes differ by 1.5 sizes for the same foot. EU sizing is gender-neutral. The most reliable approach: measure foot length in cm and consult brand-specific size charts.
Always treat size conversions as a starting point — sizes vary significantly between brands and shoe styles.
