What part of the foot does 'FOOT BALL' in the shoe size chart measure?
In the size chart, unfamiliar numbers like 6 and 8.4 are listed alongside lengths like 230 and 260, making it difficult to understand what they mean. Readers with wider feet cannot easily tell how to interpret this value.

It refers to the width across the ball of the foot, listed in this chart as 6 for 230 and 8.4 for 260[1].
In addition to length, the size chart includes another number regarding width. 6 is paired with 230, and 8.4 is paired with 260[2].
In English, "ball of the foot" refers to the widest part of the foot connecting the base of the big toe and the base of the little toe. Because shoes also need to be widest at this spot, even if the length fits, foot-pinching sensations will persist while walking if this area is tight.
Therefore, this field is useful for those who find it difficult to judge by length alone. Following the chart, as you go from 230 to 260, the value also increases from 6 to 8.4, showing that increasing the size correspondingly widens the ball area as well[3]. However, because no units are attached to these numbers, it is safer to compare how much they differ between sizes within the same chart rather than reading them as absolute measurements such as centimeters or inches.
The unit of measurement and the exact measuring standard for the FOOT BALL value have not yet been confirmed.
