The ergonomically-advanced design of the Agility paddles teaches an early vertical forearm position to increase stroke efficiency. The convex shape requires a proper palm-positive hand position. Due to the paddles' strapless design, incorrect technique will cause the paddle to fall off. Additionally, the absence of straps makes for a simplified fit, eliminating the hassle of broken or uncomfortable straps. The Agility paddles are a versatile tool for all four swim strokes and accommodate most hand sizes.
