How to measure

1 .Close against the wall, stand upright on a hard floor or surface, keeping your heels close to the wall.

2. Use a soft tape measure or ruler to measure the length from heel to toe.

3. Make sure to measure from the heel to the point farthest from the heel at the tip of the toe.

Measuring your feet as an adult

Wear socks that match the shoes you buy and measure your feet in the afternoon (feet are usually slightly swollen at this time). Make sure your weight is evenly distributed on both feet before taking the measurement.

Step 1: Fix a piece of white paper on a hard surface near a wall and stand close to the wall, keeping your heels close to the wall.

Step 2 Use a pen or pencil to mark the longest part of the foot on the paper (hereinafter referred to as foot length), and repeat the above steps with the other foot, because the size of the left and right feet may be different.

Step 3 Use a ruler to measure the heel-to-toe distance you marked for each foot.
