Frequently Asked Questions About Size 11C
Helpful fit allowances, measuring wisdom, and sizing advice for parents.
What age wears a size 11C kids shoe?
Size 11C children's shoes are typically designed for 3.5–4 years. Because children develop at different rates, measuring exact foot length in millimeters or centimeters is far more reliable than relying solely on age.
How long is a size 11C foot in inches and centimeters?
A size 11C kids shoe fits a maximum foot length of 16.5 cm (6.50 inches, or 165 mm). The actual inside cavity of the shoe should measure approximately 17.7 cm to provide recommended orthopedic wiggle room.
What is size 11C in UK and EU kids sizes?
A US kids size 11C corresponds to UK size 10 and European size EU 28. In the international Mondopoint system, this matches a foot length of 165 mm.
How much wiggle room should be in a size 11C 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.
