Frequently Asked Questions
How do I convert US shoe size to EU?
For men, add approximately 33 to the US size (US 10 = EU 43). For women, add about 31 to the US size (US 8 = EU 39). However, sizes vary between brands, so always check the specific brand's size chart when possible.
What's the difference between US men's and women's shoe sizes?
US women's sizes run about 1.5 sizes larger than men's. A women's size 9 is roughly equivalent to a men's size 7.5. This applies to US sizing only - EU sizes are unisex and the same for both genders.
How do I measure my foot for accurate shoe sizing?
Measure your feet at the end of the day when they're largest. Stand on paper, trace your foot, and measure from heel to longest toe. Measure both feet and use the larger measurement. Add 0.5-1 cm for toe room when selecting size.
Why do shoe sizes vary between brands?
There's no universal standard enforced across manufacturers. Each brand may interpret sizing differently, use different lasts (foot molds), or design for different foot shapes. Athletic shoes often run smaller than dress shoes from the same brand.
