The Aqua Sphere Zip Fins will provide a faster, smoother workout than ordinary swim fins. The cut out on these fins, just in front of the foot pocket, creates a vortex to aid in moving you forward faster. The narrow blade on these fins also allows for improvement in your kick and reduces fatigue. With the adjustable heel strap, your fins will fit perfectly and stay put.
