Accordingly, while evenly distributing pressure during your stroke, the proprietary shape creates a natural feel through the water. Additionally, the paddles' concave underside creates the perfect form by maintaining an in-line movement when correct, and throwing the hand off-course when incorrect. As a result, both your orientation and sensation in the water is enhanced, leading to a refined and efficient form on race day.
