**Foot Measurement Method:**
1. All measurements are in centimeters.
2. Place foot on white paper, mark the longest points, measure the distance for correct foot length.
3. If slight difference between left and right foot, use larger foot's data.
4. Choose a size larger for high arches or wide feet, normal size for flat arches or slim feet.
5. Measurement should align with usual shoe size; significant deviation indicates incorrect measurement or imprecise data.
**Note:** Wearing ill-fitting shoes long-term can cause injuries and blisters, affecting ankle and knee health. Choose the right size for foot comfort.
