All Fins

Without fins, humans are not efficient at moving in the water!  Just see how much effort is needed to swim a length of a swimming pool, no try the same wearing a pair of fins; no comparison!  There are two main types of a fin, full foot, and open heel; the full foot is simpler and can just be pulled on and go.  While you need to wear a pair of booties first before putting on a pair of Open Heel Fins.
