When to use this converter: Use it when shopping for shoes from international brands or online retailers that list sizes in a different system than yours. This is especially useful when ordering shoes from overseas where returning wrong sizes is expensive.
Tips and common mistakes:
- These are approximate conversions. Sizing can vary between brands and even between shoe models within the same brand.
- Always measure your foot length in centimeters or inches and compare to the brand’s specific size chart when available.
- Feet can differ slightly in size – measure both and use the larger foot for sizing.
- Shoe sizes may run differently for athletic shoes vs. dress shoes.
