Frequently asked questions
How do I measure my baby's foot?
Stand your baby on a sheet of paper (supported, with weight on the foot), mark the back of the heel and the tip of the longest toe, and measure the distance. Measure both feet in the afternoon and use the larger one. Then add about 1 cm (⅜ in) of growing room.
How much room should baby shoes have?
About a thumb's width, 1–1.5 cm (⅜–½ in), between the longest toe and the front of the shoe. Too much room causes tripping; too little squashes growing toes.
How often do baby feet grow?
Fast: roughly half a size every 2–3 months in the first two years, slowing to about every 4 months for toddlers. Check the fit every 6–8 weeks.
Do babies need shoes before walking?
No. The AAP says barefoot is best indoors to help babies develop balance and foot strength. Soft-soled shoes or socks are fine for warmth; firmer shoes are for walking outdoors.
