📏 Understanding Different Sizing Systems
🇺🇸 US Sizing
- Uses barleycorn units (1/3 inch = 8.47mm increments)
- Men’s and women’s scales offset by ~1.5 sizes
- Starts from theoretical size 0
- Most common in North America
🇬🇧 UK Sizing
- Also uses barleycorn units with different starting point
- Generally runs 0.5-1 size smaller than US
- More consistent between men’s and women’s sizing
- Standard across UK and Ireland
🇪🇺 European Sizing
- Based on centimeters (Paris point system)
- 1 size = 6.67mm (2/3 cm)
- Unisex system – same numbers for men and women
- Most logical and consistent system
⚠️ Important Fitting Notes
🎯 Sizing Variations
Brand Differences: These are approximate conversions – actual fit can vary significantly between brands
Shoe Types: Athletic shoes often run differently than dress shoes
Width Considerations: Width is not standardized across systems
Always Try On: When possible, especially when switching between sizing systems
📐 Measuring Tips
- Measure feet in the evening when naturally larger
- Measure both feet – use the larger measurement
- Consider the type of socks you’ll wear
- Account for foot conditions or orthotics
👶 Children’s Fitting
- Check sizes every 2-3 months for toddlers
- Allow 0.5-1cm (thumb width) of growing room
- Shop in afternoon when feet are larger
- Watch for signs of tight shoes: red marks, complaints
🌍 Brand Considerations
- Italian brands: Often run small
- German brands: Tend to be true to European size
- US athletic brands: May vary significantly between models
- Always check: Brand-specific size guides when available
