Why am I 21 years old and my feet are still growing!

Centimeter! It's really small, you can only wear a size 31, but maybe your feet are wide, so you can wear a size 40.

To be honest, the length of the feet of the current 12-year-old girls is almost longer than yours, and for example, there is a female student in our class who has a 12-year-old foot length and wears size 39 shoes. The smallest I've seen are all 23cm, basically between 24cm and 27cm, and the shoes range from 37 to 41 sizes.

I'm also a boy, I'm 13 years old, my feet are long, wide, I wear size 43 shoes, and I was in first grade when my feet were 21 cm long. Your feet are even shorter than my 11-year-old cousin's, and to my surprise, I saw a 7-year-old girl with longer feet than yours, and I think almost all girls in the 9 to 11 age group will have longer feet than you.

I don't know if you made a mistake, 12-year-old feet are only 21 centimeters long, how can you wear 40 sizes, when I was 11 years old, I wore 40 feet when I wore them, this is really incredible, besides, my feet are not big anymore, how can you be bigger?

You're not long enough to tell you, I'm a girl, I'm only 11 years old, and I'm old enough to wear size 38 shoes. And I'm only 148cm tall, and the oldest girl of my height only wears size 37 shoes. Sometimes I'm told:

I really don't understand why your feet are so long", are you miserable enough for me?

The specifications of many shoes are not very standard, and it is normal to be small and large.

Me too, and I wonder why
