Z2s are easy to use because they create immediate propulsion and generate force in both directions of the kick.
Their size and shape offer greater ease of movement, comfort and safety, and allow swimmers of any ability to transition the full power of their legs into the water.

The latest release from our Zoomers line of fins, Z2 fins utilize a patented angle and quick response technology to promote a shorter, faster kick.
The smaller blades make legs work harder without overloading the muscles, therefore helping you sustain better form over a longer period of time.
The higher propulsion generated by the use of Z2 supports a higher body position and better body roll for a greater level of conditioning across freestyle, backstroke or butterfly.
" The small size Z2 Fins are great for teaching our young students proper body position. The design is similar to the shape of the natural foot which makes the fins easy to use.
The children recognize they are using the same fins used by swim teams so they are eager to put them on."

"The propulsive surface area of the Z2 is increased by 20%, yet it weighs less than the original Zoomers. This makes the Z2 highly effective and allows for a faster kick at a lower amplitude, while creating a truly natural body extension," said Dr. Marty Hull, Z2 engineer and inventor.
The Z2 model results from years of ongoing field research, and now incorporates a series of new design characteristics including:
Fluid separators that reduce non-propulsive drag on the downward kick. (Figure 1) More of the effort put in comes out as propulsion.
Underside fin architecture that catches more water thereby increasing the effective propulsive surface area.
Innovative geometry that allows differential blade flexion:
The fin blade immediately bends to an ideal angle of attack on the downward kick. Propulsion begins the moment the fin starts to move down.
The underside of the fin is more resistant to flexion on the upward kicking movement. (Figure 2) No more propulsion is lost due to excessive blade flexion.

An evolved power-recovery mechanism that eliminates the lag between the movement of the foot and the tip of the fin.
An increased surface area on the underside of the fin that results in the greatest propulsive force.
The Z2 truly feels like a natural extension of the foot.
