Sandals are an open type of footwear, consisting of a sole held to the wearer's foot by straps or thongs. While the distinction between sandals and other types of footwear can sometimes be blurry (as in the case of the huaraches), the common understanding is that a sandal reveals most or all of the foot (especially the toes) to view. People may choose to wear sandals for several reasons, among them economy (sandals tend to require less material than shoes), comfort in warm weather, and (especially for women) for reasons of fashion and attractiveness.
