No matter summer or winter, I have had the experience of taking off my shoes in class.
When I was in high school, the classrooms in the school were relatively small and there were many students in each class, so our seating space was very small at that time. That experience happened in summer, and I still remember there was a Chinese class at that time. The teacher was lecturing on the platform. I turned the pen below, then I turned it off and the pen rolled directly under my desk.
Of course, I am also embarrassed to ask my classmates in the front row to help me pick up my pen. First of all, because the seating space is too small, it is inconvenient for everyone to bend over. Secondly, the teacher is still lecturing, so I am embarrassed to disturb my classmates. So, I was smart enough to pick up the pen with my feet.
Because it was summer, and I was wearing sandals, which were particularly easy to take off and would not affect others. So, when everyone was listening to the class, I quietly took off a shoe, then held the pen with my toe and finally picked it up. After picking up the pen, I put on my shoes. The whole process can be described as flowing, and I didn't affect other students.
It may be because the atmosphere in our class is more active, so the students are very friendly and get along well. Anyway, I don't think it's wrong to take off my shoes in class. This experience is the same as bending down to pick up a pen, because taking off your shoes is not the purpose, but picking up a pen is the purpose. So of course, what I care about is whether I can pick up my pen, not whether I can take off my shoes in class.
Later, when I was in college, I also took off my shoes in class. It was winter and I was wearing a pair of velvet boots and a pair of thick socks. After running from the dormitory to the classroom, I felt my socks slip down. In college, we merged two small classes into one large class, which means connecting 1 hour and a half. Originally, I wanted to insist on going back to the dormitory to sort out my socks, but the half-faded socks got stuck in the middle of my feet, which was really uncomfortable.
So in class, I took off my boots, lifted my socks, and finally put on my boots. At that time, some students saw my movements, but no one was surprised. Class is over. Nobody said that. So I think this is probably understandable.
Generally speaking, it is quite common to take off your shoes twice in class. If I hadn't seen this problem, I wouldn't have thought about my feelings at that time. Because it is a common thing like walking, there is no special experience.
Of course, as a girl, if your feet stink, it will probably be a more exciting experience if you deliberately take off your shoes in class. But I suggest you don't do this, because it will really affect your classmates. And if it is found, it will definitely be laughed at by others.
