Thongs

Thongs is a term used in English to refer to two different types of products: footwear and underwear. In many places the same word is used for both, while in others each meaning has its own common name. This article covers both senses with a neutral overview.

Footwear sense: thong sandals

Thong sandals are a type of open-toed footwear characterized by a Y-shaped strap that passes between the first and second toes and attaches to a flat sole at three points. The straps typically connect to the sole near the toes and sides, leaving most of the foot exposed. Materials vary and include rubber, plastic, foam, leather, and fabric. They are commonly worn in warm weather, at the beach, or in informal settings. Benefits include ease of wear and quick drying, while drawbacks can include limited arch support, potential for blisters, and reduced protection compared with closed footwear. In different regions, these sandals are often called “flip-flops” (notably in the United States) or “thongs” (common in Australia and several other countries).

Underwear sense: thong underwear

Thong underwear is a type of undergarment designed to minimize rear coverage, featuring a narrow back panel or string that sits between the buttocks. The front portion provides standard coverage, but the back is minimal, reducing visible panty lines under tight clothing. Variations include the G-string and T-back, which differ in the width of the back and overall design. Thongs are produced in a range of fabrics, including cotton, synthetics, lace, and satin, and are worn for everyday comfort, fashion, or as swimwear. Cultural norms regarding visibility and wear vary by country and context.

Regional usage note

In the United States, “thong” commonly refers to underwear, while in Australia and some other regions the word more often refers to the sandal style. The two meanings are etymologically distinct and unrelated beyond sharing the same word.
