Common decisions
A size 6 / 28.5 inch ball is a common starting point, but check league rules.
Leave comfortable toe room, but avoid shoes that slide or make quick stops unstable.
Ask the program which ball it uses for practices and games, then buy that specification instead of assuming age alone decides the answer. Local leagues may group players differently.
Use the socks worn for play and have the child stand, stop, and move side to side. The heel should stay in place, the toes should not feel pressured, and the foot should not slide inside the shoe.
Pick the sport and gear, then add the measurements that matter. You'll get a practical starting range, fit checks, and what to avoid.
