Sizing Systems

- US Sizes: Different scales for men and women (women's are ~1.5 sizes larger in number for the same foot)

- EU Sizes: Unisex numbering based on the Paris point (2/3 cm)

- UK Sizes: Similar to US men's but offset by 0.5-1 size

- CM (Mondopoint): Based on actual foot length in centimeters; most accurate

Key Differences

- US Men's 9 = EU 42.5 = UK 8.5 = 27.0 cm

- US Women's 8 = EU 38.5 = UK 6 = 25.0 cm

- Women's US sizes are 1.5 larger than men's (Women's 9.5 = Men's 8)

How to Measure Your Foot

- Stand on a piece of paper against a wall

- Mark the longest toe and the back of your heel

- Measure the distance in centimeters

- Measure both feet (they may differ slightly)

- Use the larger measurement and add 0.5-1 cm for comfort

## Frequently Asked Questions

**Q: How do I convert US women's to men's shoe sizes?**

A: Subtract 1.5 from the women's size to get the men's size. For example, Women's 9.5 = Men's 8. This applies to US sizing only. EU sizes are unisex, so no conversion is needed in that system.

**Q: What is the most accurate way to determine my shoe size?**

A: Measure your foot length in centimeters (Mondopoint). Stand on paper, mark heel and longest toe, and measure the distance. This measurement directly corresponds to shoe size in all systems and eliminates confusion from brand-to-brand variation.

**Q: Do EU shoe sizes vary between brands?**

A: Yes, unfortunately. While EU sizing is standardized in theory (based on the Paris point = 6.67mm), brands interpret sizes differently due to varying last shapes, toe box designs, and target fit. Nike, for example, tends to run slightly small compared to Adidas in the same EU size.

**Q: Should I size up or down when between sizes?**

A: Generally, size up. A slightly larger shoe can be improved with insoles or thicker socks, while a too-small shoe causes blisters, bunions, and discomfort. Also consider: feet swell during the day, so measure in the afternoon for the most representative size.
