If you want to wear leather shoes, you have to buy foreign trade leather shoes. There should be size 42.
You can come to me when you leave school and want to make leather shoes.
I can measure your feet, especially your feet (the last one).
If you want to look smaller, you have to make shoes with thick instep and pointed toes. But these shoes are not suitable for the growth and underdevelopment of feet.
Personal opinion, for reference only!
