We need fins to help us move through the water and while that seems quite simple it actually involved quite a lot of technology. Different blade types offer different finning characteristics, performance levels and efficiency. A standard style of blade is simply a surface to move and control water to propel the snorkeller or diver forward. More advanced fins start to add extra control panels or vents to either improve performance or reduce stress and implement flexible sections in a blade to allow the fin to flex in a controlled way for increased thrust.
