Speedo fins speedo dmc elite max fins black maximum speed and power in every kick, engineered for serious competitive training. Experience next-level speed and propulsion wearing the speedo x dmc elite max fins, created in partnership with silicone fin pioneers dmc. Engineered for the strong competitive swimmer to maximise speed, reduce fatigue and correct torque, these training fins zone in on ankle roll using an asymmetrical design and patented dmc reverse v rail rvr technology to stabilise the ankle, improve efficiency and optimise torque on each kick. The result is maximum speed and power gains with less energy lost. Next-level speed and propulsion, every length. Dmc collaboration rvr technology asymmetrical design competitive training silicone construction ankle stabilisation 3 key features patented reverse v rail technology dmc’s patented reverse v rail rvr technology is built into the blade to deliver correct torque on every kick. It works in tandem with the asymmetrical fin shape to stabilise ankle roll and increase propulsive efficiency. The outcome is a more powerful, controlled kick that translates directly into speed gains. Asymmetrical design for speed and efficiency the asymmetrical blade geometry is specifically engineered to address ankle roll, one of the most common causes of lost power and increased fatigue in fin training. By stabilising the ankle through each kick cycle, the design increases speed and reduces unnecessary energy expenditure. Competitive...
