They are effortless.  

 

When you use these fins you can’t feel the kick. Try using a friend's Zoom on one foot and another type on the other and see how easy it is to fin.

Prevent cramps.
 

Because you don’t need a lot of power in your legs. People who suffer from cramps will benefit with the ease of use.

Stops tired surface swims

 

The angle of the Zoom is set so the blade is already under the water, most of the problem with diving fins is that they are designed for under the water only and divers or snorkellers have to first kick the fin under the water. With the Zoom the work is already done.

Easy in currents
 

Because of the ease of kicking, divers fighting a current use much less energy.

One concern?

 

People often assume that they are difficult to walk in. Not so, the material they are made out of allows the fins to flatten while you walk and then go back to their original shape.
