Questions and Answers for Aeris X3 Velocity Fins with Spring Straps:
There are no questions yet.
High performance 'split fin' technology.
The Velocity X3 accelerates with lightning speed as water comes into contact with the textured blade. Faster and more efficient, the Velocity X3 maintains comfort and control while enabling you to exert less effort, stress and strain with each kick.
During the fin stroke, water flow is directed through Aeris exclusive Power Enhancing Vents (PEV's) and off the fin tips, creating lift and forward propulsion. So much so, that the Velocity X3 is the only 'paddle' fin that benefits from Nature's Wing Propeller Fin Technology. This helps reduce the stress on the divers leg while accelerating water over the blade; resulting in increased velocity. Water movement through the PEV's also reduce lateral movement of the fin (wasted energy), increasing the efficiency of the kick.
In addition, oversized side rails add rigidity for increased lift, power, and efficiency. Flexible channel directs water off the tip of the blade for improved power and efficiency. Ergonomically designed foot pocket accommodates virtually all foot sizes and boot styles. Velocity's angled blade is designed for the preferred angle of attack.
Spring fin strap have a slimmer profile then most conventional fin straps reducing the potential of fouling with lines sea weed (kelp) or debris. Easy to use springs automatically compensates for different size feet and boots. Spring fin straps are easy to put on and take off and they are depth compensating because they will compress to changes in the thickness of your boots. Fins are available in 4 sizes and come in 5 color ascent choices.

Propulsion Enhancing Vents (PEV) Fin Technology
Faster and more efficient, our PEV technology maintains comfort and control while enabling you to exert less effort, stress and strain with each stride. During the fin stroke, water flow is directed through our exclusive Power Enhancing Vents (PEV's) and off the fin tips, creating lift and forward propulsion. This helps reduce the stress on the divers leg while accelerating water over the blade; resulting in increased velocity. Water movement through the PEV's also reduce lateral movement of the fin (wasted energy), increasing the efficiency of the klick.
