Aquastrength Lower Body Fins: Ideal for those focused on strength and power training, with an emphasis on explosive or jumping movements. The Aquastrength Lower Body Fins (blue, pink and yellow options are the same resistance) provide a similar level of resistance to the Aqualogix High Resistance Fins. Their unique four blade design provides resistance in all directions whilst the V taper design makes them a very comfortable and secure fit option for longer workouts, especially those involving explosive, jumping movement.
