Barefoot refers to footwear designed with a flexible, thin sole that is shaped like a foot in order to make the shoe feel more like bare feet than traditional shoe soles. These flexible soles allow feet to have a better sense and feel of the ground while still providing foot protection. Types of barefoot footwear include toe shoes, huaraches, racing flats, hiking flats, and running shoes.
Insoles are foot-shaped pieces of material that are inserted in footwear to give extra comfort and support to the foot. Insoles may also function to assist in the proper fitting of shoes.
