1. What Is Shoe Size Calculation?

The shoe size calculator converts foot length in centimeters to US shoe sizes using standardized conversion formulas. Different formulas exist for men and women due to sizing conventions.

2. How Does The Calculator Work?

The calculator uses the standard US sizing formula:

Where:

• \( L_{cm} \) — Foot length in centimeters
• 2.54 — Conversion factor (inches to cm)
• 3 — Standard sizing scale factor
• 22 — Baseline adjustment for US men's sizes

For women: The calculator adds 1.5 sizes to the men's calculation to convert to women's sizes.

3. Importance Of Accurate Sizing

Details: Proper shoe sizing is crucial for foot health, comfort, and performance. Ill-fitting shoes can cause blisters, calluses, and long-term foot problems.
