If some people travel to Australia, they will feel very strange at first, because many people don't wear shoes in the streets, cafes, airports or other places. Even a sacred place like the library can go barefoot. Even in hot summer, the ground is very hot, and Australians don't wear shoes, which makes people admire. This is because Australians feel that wearing shoes is a constraint on themselves. If they don't wear shoes, their feet can be greatly relaxed. Moreover, there are many beaches in Australia, so people who play on the beach generally don't need shoes, so they don't wear them.
Although walking barefoot will be contaminated with dust, people in Australia are of high quality, and will not get saliva, cigarette butts and other things that may scratch their feet. So barefoot is no problem, just wash your feet a few times. Although it is strange that we walk barefoot in the street, it may be a unique culture in Australia. We should respect and understand their culture. Maybe we can try it ourselves when we travel to Australia, and we don't have to worry about other people's strange eyes.
Australia is really a magical country. Besides being unwilling to wear shoes, they have many other hobbies that are different from ours. This is the cultural difference, which can be said to be interesting.
