Zoggs Ultra Blue Fins (31039/311393.
Zoggs Ultra Blue Fins are dual density co-moulded silicone blade fins specifically engineered for optimum propulsion, performance and comfort. The foot is soft for a customised fit and features grip underneath and a tab on the heel for ease putting them on. The silicone blade is rigid and durable, creating a balanced and natural rhythmic kick as well as a reduction in muscle fatigue on the calves so you are less likely to experience cramping post swim. The short blade means that even in busier swimming pools, you can focus on your kick technique without catching the blades on the environment around you. Available with a handy mesh carry bag
