Abstract: A composite dive fin assembly for a user swimming in a body of water having primary, secondary, and lateral portions which each define corresponding oppositely disposed propulsion surfaces. The primary, secondary, and lateral portions also each having a corresponding propulsion edge. The primary, secondary, and lateral propulsion surfaces cooperatively oriented to displace an amount of water over a corresponding one of the primary, secondary, and lateral propulsion edges when the composite dive fin assembly is moved in the body of water in which the user is swimming. The primary, secondary, and lateral propulsion surfaces are cooperatively configured to displace a greater amount of water over corresponding propulsion edges relative to previously known dive fins while reducing the resistive forces while displacing water, allowing a user to swim further and/or faster with the less effort.
