Let's face it, different shoe brands fit differently. If it's a brand you know, stick with the size you've always worn. But, if the brand is new to you, here's an easy way to find your size:

1. All you need is a ruler, a pen and a piece of paper.
2. Place the paper on the ground and stand on it with your weight slightly forward to make sure your foot is flat.
3. Draw a line behind your heel and another line in front of your longest toe. Don't worry, it's common to have one foot longer than the other, so use the longer foot to measure.
4. Measure the distance between lines in inches or centimeters.
5. Find your measurement on the size chart below to figure out the best fit. Round up if your size falls in between.
