How To Buy Running Shoes Size

When it comes to buying running shoes, getting the right size is crucial for a comfortable and injury-free running experience. As a seasoned runner, I’ve learned the importance of finding the perfect fit through trial and error. In this article, I’ll be sharing my personal tips and tricks on how to buy the right running shoe size.

Start with a Proper Measurement

Before diving into the world of running shoes, it’s essential to know your foot size. Feet can change over time, so it’s a good idea to measure your feet again, even if you think you know your size. You can visit a local shoe store that offers professional foot measuring services, or you can do it yourself using a measuring tape.

To measure your foot at home, start by placing a piece of paper on the floor. Stand barefoot on the paper, and trace the outline of your foot with a pen or pencil. Measure the distance between the tip of your longest toe and the back of your heel. Use this measurement to determine your foot length.

Consider Foot Type

Understanding your foot type is crucial when choosing the right running shoe size. There are three main foot types: neutral arch, high arch, and flat feet. Knowing your foot type will help you find the appropriate level of arch support and cushioning.

If you’re uncertain about your foot type, visit a specialty running store where trained professionals can analyze your gait and recommend suitable shoes. Alternatively, you can perform a wet foot test by wetting your foot and stepping onto a piece of paper. The wet footprint will reveal your arch type.

Try Shoes in the Afternoon

Believe it or not, the size of your feet can vary throughout the day. They tend to swell after walking or running for a while, so it’s best to try on shoes in the afternoon or evening when your feet are at their largest. This will ensure that you find a size that accommodates your feet during their most swollen state.

Don’t Forget About Toe Room

When trying on running shoes, pay attention to the amount of toe room. Your toes should have enough space to wiggle comfortably, about a half-inch or the width of your thumb beyond the end of your longest toe. This will prevent discomfort and potential toenail issues during longer runs.

Run and Test

Once you’ve found a pair of running shoes that fit well, take them for a test run. Many specialty running stores have treadmills or designated running areas where you can try them out. Pay attention to how they feel while walking and running. Look for any discomfort, rubbing, or pressure points that may indicate an improper fit.

Consult Reliable Reviews

Before making a final decision, it’s always a good idea to read reviews from other runners who have already tried the shoes you’re considering. Websites like Runners World and Running Warehouse provide detailed and unbiased reviews from runners of all levels. These reviews can help you identify any potential sizing issues or unique characteristics of the shoes you’re interested in.


Buying the right running shoe size is crucial for a comfortable and enjoyable running experience. By measuring your feet, considering your foot type, trying shoes in the afternoon, ensuring enough toe room, testing the shoes, and consulting reliable reviews, you can increase your chances of finding the perfect fit. Remember, finding the right size may take some trial and error, but it’s worth the effort to keep your feet happy and healthy during your runs.
