The WaterWay Monofin DoZo is designed specifically for sports swimmers. The high-quality, durable fiberglass blade measures 50cm x 45cm/19,7 inch x 17,7 inch and features soft edges for safety. This versatile monofin improves the amplitude of the kick and trains swimmers to use their body instead of their knees. It also helps focus on the kick amplitude, allowing for fewer kicks in butterfly without sacrificing speed. This monofin is perfect for increasing foot flexibility and helping swimmers feel the water, just like top athletes who use cables to train at higher speeds. By using the DoZo monofin, athletes can experience higher speeds, work on their body position, improve overall physical strength, and enhance kicking power and stamina. It's no wonder that this monofin is becoming an essential item for top swimmers, including members of the Russian national team.
