Lutz jump
At her peak, Bobek was a strong jumper although some of her jumps did not have the best technique; for instance, she had a very marked flutz (a Lutz jump which is done from the wrong edge). She had a lasting impact on ladies' figure skating because of her signature move, a spiral with the free leg extended very high. Television commentators including Dick Button and Peggy Fleming were so complimentary of Bobek's spiral that it was widely copied by other U.S. skaters, setting off a fad for extreme flexibility moves.
