ルッツジャンプ
Figure skates are used in the sport of figure skating. Unlike hockey skates, they have "toe picks" on the front of the blade, which are usually made out of stainless steel or aluminium with a steel runner. The toe pick has a variety of uses, but is most commonly used for certain jumps in figure skating, such as the Lutz jump and toe loop, or starting a backspin. Figure skating boots are typically made of several layers of leather and the leather is very stiff to provide ankle support. In addition, the figure skate's blade is curved, allowing for minute adjustments in balance and weight distribution.
