In fact, because people wear insulated shoes for a long time, the negative electricity generated by the body has nowhere to be released.
This will have an impact on the body. Barefoot contact with the ground will release negative electricity and make the body in a better state.
Secondly, the ground is not so flat, so you can massage the soles of your feet.
There are many reflex zones on the soles of people's feet, which are also very beneficial to health.

You need as many barefoot as possible to play a role in fitness.
