Usually, it is best not to choose high heels. Although they can improve your temperament, they are not particularly comfortable to wear. And if you wear it for a long time, it will also have a certain impact on your body. If you wear it all day and walk a lot, it is recommended to massage your feet with hot water before going to bed at night. Consider it in a slightly more realistic situation or when dating a boy, but don't wear too high clothes, and also consider the height.
About socks, some girls sweat easily on their feet. Without socks, they will feel that their shoes will stick to their feet and be very uncomfortable. Some girls don't like their feet, so they don't want to show them. This depends on your own situation.
I hope I can help you spend a beautiful and cool summer.
