Proper shoe size is important for comfort and foot health. Shoes that are too big can cause just as many problems, as shoes that are too small. A shoe that is too big, can fall off, causing a tripping hazard. Not to mention the way it will rub on the back of the foot as it slides off and on when walking. Shoes that are too tight, will cramp the toes, making walking or running, extremely uncomfortable. But children's feet grow so fast that it is difficult to keep track of their size sometimes. If you are in a pinch, and don't have one of those fancy foot measurers like at the shoe store, help is just a few steps away.
Place a piece of paper on the floor.
Ask your child to step on the paper without shoes. Socks are optional.
Place a mark at the tip of the longest toe, and at the back of the heel.
Using your measuring tape, measure the length between the two in inches.
Finally, take a look at the USA sizing chart, and find your child's shoe size.
