The Speedo Biofuse Finger Paddles are designed to enhance specific aspects of your swimming technique. By keeping the palm exposed, these paddles provide a greater sense of water contact, reducing strain on the shoulders. They are particularly effective in refining the catch and pull phases of your stroke, allowing you to concentrate on optimal hand positioning. Additionally, the increased water resistance created by the finger paddles intensifies your workout, contributing to improved upper body strength and power development. In essence, Biofuse Finger Paddles offer a focused and effective means to refine stroke mechanics and enhance overall swimming performance.
