Understanding Shoe Sizing
Why Shoe Sizes Differ by Country
Historical Origins:
- Each country developed own system
- Based on different standards
- US: Based on barleycorn (1/3 inch)
- UK: Similar but starts at different point
- EU: Based on Paris point (2/3 cm)
Size Difference Examples:
Men's US 10:
- UK: 9.5 (0.5 smaller)
- EU: 44 (much larger number)
- CM: 28.0 (actual foot length)
Women's US 8:
- UK: 5.5 (2.5 smaller!)
- EU: 38.5 (larger number)
- CM: 25.0 (actual foot length)
Why This Matters:

- Essential for international shopping
- Avoids costly returns and exchanges
- Ensures proper fit
Men's vs Women's Sizing
Key Differences:
- Women's US sizes ~1.5 larger than men's for same foot
- Example: Women's US 9 = Men's US 7.5
- European sizes are unisex (same for both)
- UK sizes differ between genders too
Conversion Between Genders:
Women's to Men's:
Women's US - 1.5 = Men's US
Women's 9 - 1.5 = Men's 7.5
Men's to Women's:
Men's US + 1.5 = Women's US
Men's 10 + 1.5 = Women's 11.5
Why The Difference:
- Historical convention
- Different foot shape considerations
- Width differences between genders
- Marketing and standardization
Half Sizes Explained
US and UK Half Sizes:
- Common in US and UK systems
- Represented as .5 (e.g., 9.5)

- Sometimes uses .5 but less common
- Each size is 2/3 cm (6.67mm)
- Example: 43, 44, 45 (no 43.5 usually)
Kids' Sizing:
- Half sizes very common
- Kids' feet vary more
- Growth happens in small increments
- More precision needed
Finding Half Sizes:
- If unavailable, size up
- Better too big than too small
- Use insoles if needed
- Try brand's specific sizing
Width Considerations
Width Sizes (Common in US):
- B: Narrow (women's standard)
- D: Medium (men's standard)
- E or EE: Wide
- EEE: Extra wide
