The Arena Tech Fin is a short swim training fin that has a curved blade, side ribs and open heel design. This lightweight swim fin is quite rigid and firm to give more resistance which means a tougher workout for more advanced swimmers. The blade is located above the foot and the foot pocket is ergonomic for maximum comfort.
I listened to the video explaining the purpose of these flippers: good advice to listen to when making a purchase choice. Really enjoy using these flippers:light and effective.
