For example, a Mercurial soccer cleat is made with a different last than a pair of Air Force 1s. A last is the footform that a shoe is built on, and different shoes (including different Nike shoes) are made with different lasts.

The shoe’s last and overall structure.

There are a handful of factors that can affect the way a shoe feels on your feet: Using the measurement tools in this guide is a great way to determine the right shoe size, but it’s important to note that different shoes have different designs and purposes, which may impact the way two different shoes feel on your feet, even if they are the same size. If you’d like expert tips and advice from a Nike teammate, head to your local Nike store to try on different styles in person. For example, if you’re shopping for running shoes, consider testing how they feel by taking a quick jog around the block while wearing them. Tip: When trying on a pair of Nike shoes to assess the fit, be sure to mimic whatever movement you intend to perform in them. In a shoe that is too big, this might happen even when the laces are tied tight. In a shoe too small, it might land too close to the ball of your foot. If the shoe is too big, the arch might land too close to your heel. The shoe’s arch is in the wrong place.

If a shoe collar is too high, for example, you might experience redness or blisters on your ankle bone (indicating a too-large fit). If a shoe is too small, you might experience pinching or irritation on the edge of your big toe or pinky toe. That said, there are a handful of telltale signs to look out for if you suspect you’re wearing wrong shoe size, including: When a shoe fits correctly, you should be able to perform your desired movement - be it walking, running or playing a sport - with comfort and confidence in your feet.

If your feet are two different sizes, use the foot measurements of the larger foot when comparing your measurements against a size chart.

There are several Nike shoe icons that are made in wide and extra-wide fits, including the Nike Pegasus and the Nike Monarch. If you find that a standard-size shoe feels too narrow on your foot, you may want to explore wide or extra-wide styles. Note: Nike shoe sizes are based on foot length. (For the most precise measurement, consider using a ruler with centimeters, rather than inches.) This measurement represents the length of your feet.

Mark the tip of the big toe and the outermost part of the heel, and use a ruler or measuring tape to measure the distance between the two points.

It’s common for a person’s feet to be two slightly different sizes. Repeat the process with the other foot.That way, you can keep your feet still and capture the most accurate measurement. If possible, ask another person to help you with this step. With a pen or pencil pointed straight down, trace the outline of your foot on the paper.You can also sit in a chair, but make sure your feet are firmly planted on the ground. Stand with one foot on the paper and a slight bend in your knees.Tape a piece of paper to a hard floor, ensuring the paper doesn’t slip.Before measuring, put on the same pair of socks you plan to wear with the shoes.

Feet tend to swell throughout the day and may have a slightly larger measurement in the evening than in the morning.
