A traditional pair of sandals feature a fairly rugged sole and adjustable straps to help them fit your feet. These classic sandals are made for walking on a variety of terrain such as the street, beach, or trail. But barefoot slip-on sandals are much thinner and lighter in weight, and they also expose more of the foot than regular sandals do. Many designs are simply made to add a decorative touch to your foot while allowing you to walk barefoot on the sand or grass.
The sole of barefoot sandals should be so thin that it feels like you’re walking directly on the ground. Traditional sandals have a much thicker, less flexible sole, which makes them more appropriate for walking long distances and in different environments. However, you will find some barefoot running sandals that help make jogging and running outdoors feel more natural.
