A diving boot usually refers to a type of diving equipment, specifically a heavy boot used by divers to help them descend more easily and maintain stability underwater.

Made of bronze or similar alloys, these boots are heavy, providing the necessary weight for divers to overcome buoyancy and submerge effectively. They are often designed to fit snugly over a diver's suit or wetsuit and may include a reinforced sole for added strength and grip. The weight helps stabilize the diver in the water, making it easier to maintain an upright position or control movement through the duration of the dives.

Heavy bronze boots are part of the diving suit. A diving suit is a waterproof type of underwater suit that helps the diver to stay in the water environment for a long time, depending on an umbilical cord, through which air is supplied and in many cases communication with the surface. It is mainly used in professional diving, although lighter variations are occasionally introduced into recreational diving. The diver in scuba diving does not swim but walks.

Historically, the first waterproof diving suits were developed during the industrial revolution in England, by the company founded there by Augustus Siebbe. In 1837, the first metal helmet was put into production, connected to a watertight elastic suit, with air supply from a pump on the surface. The set of helmet, suit and boots with lead plates became the prototype and stereotype at the same time of the clothing of divers, especially those engaged in sponge diving.
