Speedo Nemesis Fins inspired by Humpback Whales

Inspired by the humpback whale fin, which features knobby bits along the front edge to create extra lift for the whale from the flow of water, the Speed Nemesis Fins allows the swimmer to go faster by pushing more water with every kick. The square openings along the inside edges of the fins take it further by providing more resistance on down kicks.
