New for 2017, Switchblade Fins by Speedo were designed for premier performance and unmatched comfort. They're the ideal fin for professional athletes, surfers, and fitness swimmers. As Speedo product manager, Grace Anne Sanderson puts it, Switchblades are "the fin that everyone has been asking for." Designers in the Speedo lab tested numerous blade designs, seeking the blade shape with the greatest balance.
The Finis Z2 Zoomers are a short blade swim training fin specially designed to optimize your cardio and strength conditioning leg workout. These short blade swim training fins engage the leg and core muscles for a more intense workout. The added resistance due to the larger surface of area of a fin compared to your foot helps increase leg strength. Still, the Finis Z2 Zoomers displace less water than longer blade swim fins, allowing for more cardio and strength training benefit.
Kids absolutely love the design of this fin! Shaped just like a mythical mermaid's fin, this Finis model is great for young swimmers. Even children who are more apprehensive of the water find the pool toy hard to resist. And that's what is so great about the Mermaid Monofin. It not only helps propel a child through the water, but it also allows him or her to feel more comfortable and confident while in the pool.
