why the sole of our shoe wear out.
A 7.5
It means left sock, right sock, left shoe, right shoe
They were a small leather boot type shoe. No right/left feet and no hard sole. They would slip on or use laces to close the shoe so it would stay on. I have a pair made in the "old way" and they are pretty comfortable to wear.
Wear 4 pairs of socks.
the shoe size is 11
No. You can wear it inside the shoe, but not outside of the shoe
You should wear a shoe with a heel. Also consider the fabric of the gown when choosing the shoe.
Yes and no. When you buy them, there is no definite left or right shoe whether it's a soft shoe or pointe shoe and even some jazz shoes. More in pointe shoes, as you start to wear them you decide which shoe works or feels better on which foot. The only time when you buy them, that I can think of, that you might have a right or left shoe is if one foot is bigger than the other. A lot of people (depending to the size difference) get two different pairs and each pair is a different size.
There is no official presidential shoe.

They ware out like any normal running shoe. You can check the details on what the shoe is made of in order to see if it will last longer. but most running shoes are the same.
