The Alpha Fins from Aqua Sphere are an unusually shaped swim training fin that are 70% lighter than traditional swim fins. This gives much more buoyancy to lift your body higher in the water and improve your body position. The blade is located on top of the foot pocket for optimum power transfer and a full arch support provides added comfort. The specific left and right foot design achieves a better kicking motion and encourages body rotation. A super light, soft and very comfortable swim fin for swim training.

Gives my daughter so much extra enjoyment as part of her swim routine
These fins are really stiff so be prepared for soreness after your first couple of workouts as they'll work your hip flexers pretty intensely. Otherwise they're super light and fit great. I'm a size 12, regular (US) and they fit perfectly.
