Scuba flippers are commonly known as scuba fins or swim fins. Typically made from rubber or plastic, this dive gear is highly engineered to increase precision and to aid in movement underwater.

The fins can be worn on the foot or leg and have different designs depending on which water sport they are to be used. Most scuba flippers come in pairs, though there are also single fins or mono fins that are usually worn for free diving and fin swimming. Some fins, like the full-foot fin, can be worn over bare feet. The open-heel fins are the most commonly used type of fins by divers, as these can be worn over swimming shoes or boots.
