## Frequently Asked Questions

**Q: How do I measure my foot correctly?**

A: Stand barefoot on a flat surface with your heel against a straight edge. Measure from the back of your heel to the tip of your longest toe (which is not always the big toe). Measure in the afternoon when feet are slightly swollen, and measure both feet since one is usually larger.

**Q: Why do shoe sizes vary between brands?**

A: There is no universal standard enforced on shoe manufacturers. Sizes can vary by up to a full size between brands due to different lasts (foot molds), manufacturing tolerances, and regional sizing conventions. Always try shoes on when possible.

**Q: What is the difference between men's and women's sizing?**

A: Women's US sizes are typically 1.5 sizes higher than men's for the same foot length. For example, a men's size 8 is approximately a women's size 9.5. UK sizes also differ between men and women.

**Q: How should I choose width?**

A: Standard width is D for men and B for women. If your feet feel squeezed in standard shoes, try wide (E or 2E). If standard shoes feel loose, try narrow (B for men, AA for women). Width measurements are based on the widest part of your foot.
