However, if you are measuring the feet of your kid, then it would be best to hold their feet tight so that it completely touches the ground. For shoes or hiking boots, you should wear socks to get better results.
  • Now using a pencil or marker, mark the line by drawing another perpendicular line at the tip of the heel and biggest toe of your feet. While drawing, you should ask your family member or friend to hold the pencil or marker perpendicularly. Similarly, you should do the same when marking the line of your kid’s feet.
  • Once you have marked the points on the line, it is time to measure the distance between the marks. Use the measuring tape to calculate the distance and use the larger measurement for finding the correct shoe size. While trying on the shoes, you should wear socks.

Now that you have measured your fee or your kids’ feet, it is time to check them on the Ugg sizing chart. Some of the Ugg boots run big, so you should keep this factor in mind;
