Roller skates are a kind of leisure sports goods, which are divided into roller skates, roller skates and roller skates. The soles of roller skates are sharp blades, roller skates have two rows of four wheels, and roller skates have a row of four wheels. Using the principle of rolling and sliding, people can slide down at high speed and make all kinds of gorgeous movements.
Tips for choosing skates:
1, see if the blade is straight.
Turn the skates upside down and lift them up, with the skates facing up and the shoes facing down. Use one eye to see if the blade is in a straight line. The straighter the blade, the better. Whether there is a deep cut on the blade, if there is a deep cut on the blade, it will affect the skating effect, so try to choose skates with shallow cuts when buying new shoes.
2. See if the skates are bright.
Some skates began to rust and silver plating fell off due to poor steel or silver plating. Good skates should be bright and have no rust on the surface.
3. See if the bearing is smooth.
Bearings are metal objects placed in the middle of wheels to help them turn. A bearing should be placed on both sides of each wheel, and the middle is separated by a sleeve. Plastic sleeves for ordinary single-row shoes and aluminum/brass spacers for advanced shoes; The friction of metal is small, which can give the bearing the maximum continuous rotation ability, so the wheel rotates at a higher speed.
See the connection between skates and skates?
Generally, skates are perpendicular to them. The skates should be in the middle of the skates. The left blade of speed skating slightly deflects about 15 degrees to the right, and the right blade slightly deflects about 15 degrees to the left.
5. See if the quantity is appropriate.
The number of skates must be suitable for me, neither too big nor too small. When trying on shoes, you should loosen all the shoelaces and then fasten them in turn. You must make sure that the quantity is appropriate before you buy it. Never make do with it.
