Frequently Asked Questions About Size 10C
Helpful fit allowances, measuring wisdom, and sizing advice for parents.
What age wears a size 10C kids shoe?

How long is a size 10C foot in inches and centimeters?
A size 10C kids shoe fits a maximum foot length of 15.7 cm (6.18 inches, or 157 mm). The actual inside cavity of the shoe should measure approximately 16.9 cm to provide recommended orthopedic wiggle room.
What is size 10C in UK and EU kids sizes?
A US kids size 10C corresponds to UK size 9 and European size EU 27. In the international Mondopoint system, this matches a foot length of 157 mm.
How much wiggle room should be in a size 10C shoe?
Pediatric podiatrists recommend 10 mm to 12 mm (roughly 0.5 inch or a full thumbnail width) of clear space between your child's longest toe and the front of the shoe to prevent cramped toes and encourage healthy foot bone formation.
