Kids shoe sizes repeat numbers across infant, child, and youth ranges. Keep C/Y labels visible to avoid choosing the wrong range.

How to measure before choosing a size

Measure both feet while standing; use the longer foot for the chart.
Measure in the afternoon or evening because feet can expand during the day.
Leave about 0.5-1.0 cm of toe room for adults and about 0.8-1.2 cm of growing room for kids, depending on shoe type.
Use CM/JP or Mondopoint length as the most stable cross-check, then confirm US, UK, and EU labels by brand.

FAQ

Should kids shoe size be based on age?

Age is only a rough estimate. Foot length is the most reliable way to choose kids shoes.

How much room should kids have in shoes?

Many kids need about 0.8-1.2 cm of extra room for growth and toe movement, depending on shoe type.

What does C or Y mean in kids shoes?

C usually means child sizes and Y means youth sizes. Keeping the suffix prevents confusing repeated numbers.
