How to measure your child’s feet for See Kai Run

Buying tips and my field notes
After years fitting kids, here is what saves time and money:
- Order two sizes if you are unsure. Try at home on clean floors.
- Keep the box and tags until you test fit with socks and a few laps around the room.
- Measure midweek, late day, and redo if your child was squirmy.
- Trust the toe and heel tests over the number on the box.
