When a person walks barefoot, the muscles and ligaments of the foot are fully activated and working.
In addition, blood flow improves due to stimulation by various textures, as well as differences in their temperature and tactile characteristics.
Why is it good to walk without shoes
Walking barefoot on a bumpy or uneven surface is considered one of the best means of preventing and treating flat feet.
While walking on a sandy or pebble beach, grass or uneven road, the muscular-ligamentous system actively works and, as a result, becomes stronger and more resilient.
According to research in the field of orthopedics and physical therapy, walking without shoes is an excellent prevention of flat feet, as well as its consequences.
One small study found that running barefoot for eight weeks didn't actually have much of an impact on strength and proprioception.
