If shoe sizes are listed using a system you aren't familiar with, it can be difficult to know how to buy shoes that will fit. Most of the shoes listed on Overstock.com are in U.S. sizes, which can make purchasing shoes online confusing if you are shopping internationally. This international shoe size conversion guide is here to give you an easy reference when you're shopping for shoes online.

If it has been a while since you measured your feet, you'll want to do that first. Measure them late in the day, as they tend to be larger at this time. You should also wear the socks you plan to wear with your shoes. Have a friend trace your foot on a piece of paper, so you can stand up straight. Measure the tracing, finding the length of your foot in inches closest to the next 16th inch. Find the width of your foot, and then measure your other foot; use the measurements from the largest foot when referring to the shoe size conversion table.

Remember that, even with the correct shoe size, shoes from different manufacturers will fit differently. Be sure to read customer reviews to see if the shoes you are shopping for run true to size.
