It is because every country has a different standard for shoe size…, and of course, some of them are more tiresome than others to grasp. Japanese shoe sizes are one of them.

Japanese shoe size to US womens is also a little narrower which can be a blessing or a curse depending on your foot shape. Sizes are listed in some stores as S, M, L, and LL rather than centimeters (sometimes LLL). An S is approximately 23cm, an M is approximately 23.5cm, an L is approximately 24cm, and LL is approximately 24.5cm, or an LLL is approximately 25cm (sometimes 26cm).

There is also a section called “model size”; which is code for large-size shoes (over 24 cm). Actually, it makes sense; tall women with model-like figures have larger feet. So, instead of thinking of it as having big feet, think of it as having model-size feet!

4.2. Yohji Yamamoto

Let us now discuss the Japanese shoe size by Yohji Yamamoto. Yohji likes to keep us guessing by using a variety of different sizing methods. Pour Homme, Costume d’Homme, and Y’s mainline all use the 1-6 number system. This can be difficult to convert directly into Western measurements. Y’s sizing for men varied, but they typically used only four size variations: S/M/L/XL. Y-3 shoes are almost always marked with standard global multiple sizes. This makes things a lot easier. Thank you, Y-3!

V. How to measure the right foot size for shoe size? 

When it comes to footwear, a bad fit can stifle your style and distract you from your work. Incorrect shoe size can have a negative impact not only on your feet and back, but also on your activities. Fortunately, determining your foot size is a simple procedure. Here’s how we break it down.

5.1. Step-by-step guide on measuring the right foot size

When measuring your shoe size at home, you’ll need the following items:

  • Two pieces of paper larger than your foot
  • Tape
  • Writing utensil
  • Ruler

NOTE: Before taking your measurement, put on the socks you plan to wear with your shoes. Because you might wear thicker socks with hiking boots than you would with running shoes. Wait until your foot is at its widest point at the end of the day before doing so.

Step 1. Tape one end of the paper to the floor and the other end to a wall.

It’s critical that it doesn’t slip so that you can get the proper measurement.

Step 2. Place one foot on the paper, and heel up against the wall.

Step 3. Make a trace of your foot. 

It is easiest if you have someone assist you with this step. Avoid holding the pencil at an angle, as this can result in an incorrect measurement.

Step 5. Repeat with your other foot.

Make a note of your measurements in both inches and centimeters. The units used in charts may differ. When comparing your results to a shoe size chart, use the measurement of your larger foot.

5.2. Troubleshooting tips

Even if you’ve followed all of the steps to determine your shoe size, it may take a few wears to determine the best fit. Here are a few methods for determining whether your shoes are too big or too small.

Blisters forming on the tops of or between your toes could indicate that your shoes are too small. A shoe that is too small can lead to calluses, as well as your foot falling asleep or cramping. Whereas,  Blisters on the ball of your foot indicate that your shoe is too wide.

Athletic footwear typically requires a half size larger than a typical dress shoe. If you have bruised toes while running, it could be a sign that your shoes aren’t long enough. If your heel is slipping, experimenting with a different lacing technique may help. If that doesn’t work, try a different insole or a smaller shoe size.

Remember that your feet can grow and change over time. Other factors, such as arch type and foot shape, may influence how well your shoes fit. Using these pro tips to measure your feet on a regular basis can help you maintain comfort from shoe to sole.
