Kids shoe sizes repeat numbers across infant, child, and youth ranges. Keep C/Y labels visible to avoid choosing the wrong range.
Shoe width guide
Width matters when the length conversion looks right but the shoe still feels tight or unstable.
| Width | Common men's label | Common women's label | Fit sign | What to do |
|---|---|---|---|---|
| Narrow | B or N | AA-B | Feet slide forward less, but sides feel tight | Try standard width first only if brand runs wide |
| Standard / Medium | D or M | B or M | Most default shoe listings | Best starting point for conversion charts |
| Wide | 2E or W | D or W | Toes or forefoot feel compressed | Use wide width instead of sizing up only for width |
| Extra wide | 4E+ or XW | 2E+ or XW | Ball of foot spills over midsole | Prioritize brands with extended-width models |
Width labels vary by brand. If length is correct but the forefoot feels tight, a wide width is usually better than sizing up.

FAQ
What is the most accurate way to use a shoe size chart?
Measure foot length in centimeters while standing, use the longer foot, then compare CM/JP, US, UK, and EU labels. Brand-specific charts should confirm the final size.
Are US men's and women's shoe sizes the same?
No. In US sizing, women's labels are commonly about 1.5 sizes higher than men's for a similar foot length, but brand conversions can vary.
Are EU shoe sizes unisex?
EU labels are often used across men's and women's shoes, but width, last shape, and brand fit can still differ.
