What is the thickness of general shoes in cm?

Shoes have a long history of development. During the Yangshao Culture period about 5,000 years ago, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. The earliest people invented fur shoes in order to overcome special situations and prevent their feet from being uncomfortable or injured. Shoes have developed to this day and have become what they are now. Shoes of various styles and functions can be found everywhere.
