Running barefoot, or barefoot running, opens up a different realm from the running you have known so far. This new running trend aims to run using the natural foot, without traditional shoes. This method of running can help strengthen foot muscles and improve running efficiency. Recently, studies have been increasing that suggest running barefoot may be effective in preventing injuries. According to a 2010 study by Harvard University, people who ran barefoot had a lower incidence of injuries compared to those who wore cushioned running shoes. Additionally, running barefoot makes the foot's senses more sensitive, allowing better adaptation to various terrains. The sensation in the soles is connected to the sense of balance, helping to run in a natural posture. As a result, it reduces the stress on joints such as the ankles, knees, and hips, thereby reducing the burden of running. To start running barefoot, a preparation process is necessary. It is important to adapt slowly rather than attempting excessive running distances from the beginning. Starting with about 10 minutes of barefoot walking a day and gradually increasing the time will naturally help your feet adapt. Especially in rough terrains, caution is needed, so it's good to start in soft places like parks or grassy areas. Wearing barefoot running shoes is also an option. These shoes protect the feet while providing an experience close to being barefoot. However, not everyone is suitable for running barefoot. There are individual differences depending on the structure of the foot or existing injuries, so it is recommended to consult with an expert when starting. If you want to find the essential joy of running, challenge yourself to run barefoot. The feeling of becoming one with nature, the sensation of the ground felt in each toe, will invigorate you with new vitality. Recording your daily life of new challenges through the 'Daily Certification' app and sharing experiences with others who have started the same challenge is also a good way.
