With its short blade, the Z2 Gold Zoomers® fin encourages shorter and faster kicks while experiencing propulsion through the water. The comfort of natural rubber creates a soft and secure fit and inhibits hyperflexion. The flex box on the bottom of the fin helps catch water on the up kick, targeting and strengthening hamstrings and glutes. The fluid separator on top of the fin allows the foot to easily cut through the water while reducing fatigue on the down kick and quads.
