Frequently Asked Questions

Q

How do I convert US shoe size to EU?

For men: EU = (US + 33). For women: EU = (US + 31). For example, US men's 10 = EU 43, and US women's 8 = EU 39. Our converter handles all conversions automatically.

  • Men's formula: EU size ≈ US size + 33 (e.g., US 9 = EU 42)
  • Women's formula: EU size ≈ US size + 31 (e.g., US 7 = EU 38)
  • EU sizes use the Paris Point system: 1 size = 6.67 mm
  • Half sizes exist in US/UK but not in all EU brands
  • Always check brand-specific charts – EU sizing varies by manufacturer

Q

What is the difference between UK and US shoe sizes?

UK sizes are typically 0.5-1 size smaller than US sizes for men, and 2 sizes smaller for women. For example, US men's 10 = UK 9.5, and US women's 8 = UK 6.

  • Men: UK size = US size – 0.5 to 1 (US 10 = UK 9–9.5)
  • Women: UK size = US size – 2 (US 8 = UK 6)
  • Children's sizes are the same in US and UK up to size 13
  • Both systems use half-size increments (≈ 4.23 mm per half size)
  • UK sizes start from size 0 at 4 inches (10.16 cm) foot length
Q

How do I measure my foot for shoe size?

Stand on paper, trace your foot outline, and measure from heel to longest toe in centimeters. Add 0.5-1cm for comfort. Compare with size charts - foot length is the most accurate way to find your size.

  • Measure at the end of the day when feet are largest (up to 4% bigger)
  • Stand with full weight on the foot for accurate length
  • Add 10–15 mm (0.4–0.6 in) beyond your longest toe for comfort
  • Measure both feet – one foot is typically 2–5 mm longer
  • Use the larger foot measurement to determine shoe size
Q

Are men's and women's shoe sizes different?

Yes, women's US sizes are typically 1.5-2 sizes higher than men's for the same foot length. A men's US 8 equals approximately a women's US 9.5-10.

  • Women's US size = Men's US size + 1.5 (e.g., Men's 8 ≈ Women's 9.5)
  • Men's shoes are built on wider lasts (D width vs B width)
  • Average US men's size: 10.5, average women's size: 8.5
  • Unisex shoes usually use men's sizing
  • Width designations differ: Women's D = Men's B (narrow)

Q

What is JP shoe size?

Japanese (JP) shoe sizes are measured in centimeters and represent the actual foot length. For example, JP 27 means a 27cm foot length. This is the simplest international system.

  • JP sizes equal foot length in cm (JP 27 = 27 cm foot)
  • Increments are 0.5 cm (JP 25.0, 25.5, 26.0, etc.)
  • Men's range: JP 24.0–30.0, Women's range: JP 22.0–26.0
  • No conversion formula needed – just measure your foot in cm
  • Also called Mondopoint when used internationally (ISO 9407)
