Why are open heel fins usually preferred by scuba divers?

Open heel fins are widely preferred by scuba divers primarily due to their versatility in various environmental conditions. These fins allow divers to wear different types of booties, which can be advantageous when dealing with fluctuating water temperatures or varying surfaces. For example, when diving in colder waters, divers can wear thicker neoprene boots for insulation, while lighter boots can be used in warmer waters.

The open heel design not only accommodates these boot options but also contributes to a better fit and comfort, which is crucial during long dives. Additionally, the open structure helps in removing the fins more easily, which is particularly beneficial when adjusting to different dive sites or when exiting the water in certain conditions.

In contrast, other factors such as color appeal or cost might influence a diver's decision but do not provide significant performance or functional benefits when it comes to the demands of varying diving environments.
