Powerfin Pro II Flex Swim Training Fins – Midnight Blue

Powerfin Pro II Flex swim fins from Arena are designed for competitive swimmers seeking to refine their kick, strengthen their legs and develop power in the water. Short, angled blades and softer, more flexible silicone balance propulsion, control and comfort, even during long training sessions.

The short, angled blades promote efficient forward propulsion and fast, controlled kicks. By targeting lower-body muscles, these training fins build leg strength and endurance while improving swimming technique.

Made from 100% soft, durable silicone, Powerfin Pro II Flex fins fit comfortably and help reduce the risk of blisters during extended training. Their heel and open-toe design encourages ankle mobility and a more natural range of motion in the water.

Each fin is shaped specifically for the left or right foot for a precise fit and better movement control. Lightweight and PVC-free, they suit swimmers seeking both performance and comfort at every session.
