What measurement is 'FOOT BALL' in the shoe size chart?
While looking at the size chart to choose shoes, you stop at an unfamiliar term next to the length item. You need to know how to use this number to determine your size.
FOOT BALL in the shoe size chart refers to the ball of the foot, which is the widest part of the foot, and six steps from 8.5 to 9.25 are listed.
Let us look at the numbers first: 8.5, 8.65, 8.8, 8.95, 9.1, 9.25 — each time the size goes up by one step, this value also increases by the same interval[1].
The ball refers to the widest part of the foot, connecting the base of the big toe and the base of the pinky toe. Since the feeling of a shoe being tight or loose often comes from this spot before length, even if foot length is the same, people with wide balls and narrow balls will find different sizes comfortable. When measuring it yourself, stand on the floor with your weight on your feet and measure the width of that widest point, and checking it once more in the afternoon when your feet are slightly swollen will get you closer to the actual fit.
However, it has not been confirmed what unit the numbers in this chart are written in. Therefore, rather than comparing it directly with your foot measurements, it is safer to read it as a scale to gauge how much the ball width differs between sizes.
hmmm, a chart that sets ball measurements separately next to length is close to a signal not to decide size solely by length.
It has not yet been confirmed in what unit the FOOT BALL value is indicated, nor whether it is circumference or width.
