Flip turns have a mystique about them. Walk up to any pool and watch folks swimming laps. Your eyes will immediately go to the swimmers who do flip turns at the walls. It doesn’t matter if they are faster than the other swimmers, they will look fiercer because of the flip turn. Conversely, if, instead of doing flip turns, you saw Katie Ledecky or Michael Phelps sticking their heads up at the walls, gulping air, turning awkwardly half out of the water, then plunging back in for the next lap, they would seem significantly less fierce.
