A team of industry experts deconstructed 40 different fins and worked with countless athletes on the quest to develop the Switchblade. Engineered with a 10 blade angle to provide maximum propulsion, stability and engagement throughout your entire kick cycle. Unlike other fins, Switchblade allows for an increased kick cadence with ease and fluidity, promoting better stroke technique all-around. Its the fin that every swimmer has been asking for. Precisely engineered to prevent breaking the water surface, maximising down kick engagement. The delta-shaped blade with a notched tip is proven to maximise drive, propulsion and stability. Sculpted side rails add strength and stability. Focused on mid-foot flex points, the foot pocket flex zones provide increased comfort and durability.
