Speedo fins speedo dmc elite max fins diva speedo black speedo x dmc elite max fins, engineered for elite-level speed and propulsion in the pool. Experience next-level speed and propulsion wearing the speedo x dmc elite max fins, created in partnership with silicone fin pioneers dmc. Engineered for strong elite swimmers, these training fins zone in on ankle roll, utilising 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. Made from dmc’s silform silicone for superior comfort during even the most demanding training sessions. Maximum speed. Maximum power. Minimum energy lost. Elite training fins dmc rvr technology asymmetrical design silform silicone reduces fatigue bottom drain chute 3 key features patented rvr technology dmc’s patented reverse v rail technology is the engineering core of these fins. The rvr design is geared to deliver correct torque for each kick, stabilising the ankle throughout the stroke cycle. The outcome is measurably improved efficiency and greater propulsion with every push. Asymmetrical fin design the asymmetrical blade shape mirrors the natural mechanics of a swimmer’s kick, targeting ankle roll precisely where it matters. This design focus reduces wasted movement and channels energy into forward drive. Strong elite swimmers will notice the difference in speed gains almost immediately....
