Figure skater: An ice skate with protruding teeth in front. The principle of sliding is the same as that of walking. Figure skating is difficult and requires high stability, so the waist is hard and high, which protects the ankle knife. The blade is wide, with a groove in the middle, and the blade is curved, which is convenient for rotation, rotation and footwork. The front end of the blade has teeth, which is convenient for braking, jumping, falling and rotating. At present, beginners generally choose figure skating shoes;
The quality of a pair of shoes depends on its rigidity. There are two ways to look at this problem: one is ankle. This part is an important part to support the weight of the body, and it must be hard enough to keep the ankle and calf in a straight line, so that even if the athlete accidentally falls, it will not bend. Because of bending over, exercisers are likely to sprain their feet. In addition to the high ankle cladding, there must be a movable "knot". In order to reduce the cost, some skates only "attach" the node of "decoration" condition on the skates, which greatly reduces the sensitivity of activities;
