The part of the fin where the foot is placed. It can be completely closed, like in full-foot fins, or open with an adjustable strap, like in adjustable fins.
The flat part of the fin that helps to generate the thrust. The longer and/or harder the blade, the more powerful the fins. The shorter and/or more flexible the blade, the less powerful the fins.
Storing your fins
A little tip: both fins can be clipped together (clips on the toe of each fin) to make carrying easier.
