Speedo fins speedo dmc elite max fins blue maximum speed and propulsion, engineered in partnership with silicone fin pioneers dmc. 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 competitive swimmers, 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 from every kick. Dmc collaboration rvr technology asymmetrical design competitive training ankle stabilisation silform silicone 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 stabilises the ankle throughout the kick cycle, reducing energy wastage and improving overall stroke efficiency. This is the core innovation that separates the elite max from conventional training fins. Asymmetrical blade design the asymmetrical fin shape is engineered specifically to counteract ankle roll, a common cause of fatigue and reduced propulsion in distance training sets. By correcting the ankle’s natural tendency to splay, the design increases speed and decreases muscular fatigue. Stronger swimmers will feel the difference across every rep.
