There are 3 steps that you should know.

1. Gather paper (legal size is good for most adults), a pencil, and a long ruler or tape measure.
2. Trace feet in the evening, after the feet, have swollen to their maximum size.
3. Keep in mind different ice skating brands have different sizing charts.

Step 1. Stand up straight on a hard surface with your heel against the wall and a piece of blank paper taped to the floor, flush against the wall beneath your foot.	Step 2. Have someone mark the longest part of your foot (referred to as heel-to-toe length) on the paper with a pen or pencil, or measure yourself if necessary. Repeat with the other foot, as right and left sizes may be different.	Step 3. Use a ruler to measure the heel-to-toe length you marked for each foot.
