The Wikipedia has the following information about this codepoint:
Sandals are an open type of shoe, consisting of a sole held to the wearer's foot by straps going over the instep and around the ankle. Sandals can also have a heel. While the distinction between sandals and other types of footwear can sometimes be blurry (as in the case of huaraches—the woven leather footwear seen in Mexico, and peep-toe pumps), the common understanding is that a sandal leaves all or most of the foot exposed.
People may choose to wear sandals for several reasons, among them comfort in warm weather, economy (sandals tend to require less material than shoes and are usually easier to construct), and as a fashion choice. Usually, people wear sandals in warmer climates or during warmer parts of the year in order to keep their feet cool and dry. The risk of developing athlete's foot is lower than with enclosed shoes, and the wearing of sandals may be part of the treatment regimen for such an infection.
