When choosing a wheel carrier, we should pay attention to whether the connection between the upper and the sole is firm, and whether the connection between the wheel carrier and the wheel plate is tight and seamless. The wheel frame must be located in the center of the sole, otherwise it is difficult to complete difficult movements.
The bearing on the wheel determines the elasticity of the shoes. A good shaft looks exquisite and works exquisitely. Both bearing covers shall be marked with the words "608 ZABEC-X", where 60 indicates that the circumference of the outer ring of the bearing is 60mm, 8 indicates that the diameter of the inner ring is 8mm, Z indicates the metal dust covers on both sides, ZZ indicates the metal dust covers, and ABEC indicates the bearing grade. The higher the number, the better the bearing accuracy (grade 65438).
You can put the shoes on the flat ground and push them forward to observe the sliding direction of the shoes. Good shoes should have a long sliding distance and a straight sliding line.
Wheels are usually made of three different materials, namely plastic, resin and polyester. Plastic and resin wheels are a little cheaper, but they have poor wear resistance and heat resistance. Good wheels are polyester, wear-resistant and heat-resistant, and can slide for a long time. It is necessary for people who practice for a long time to choose polyester wheels.
For beginners, it is very important to have roller skates with appropriate size, otherwise it will affect the correct mastery of technical movements and cause injury accidents; In addition, roller skates should be selected according to the types of roller skating. Speed roller skating, figure roller skating, roller skating ball and extreme roller skating have different requirements for shoes. Confirm whether the quality of the selected roller skates meets the standard, which is the premise to ensure safety.
In addition, novices need to pay attention to: the thickness of the inner sleeve and whether it is comfortable to wear are the key to choosing shoes. The thicker the inner sleeve, the softer the tongue. Only shoes that fit the foot can protect the ankle and make the movement more flexible-a good shoe body should be strong enough, and the sponge should be thick enough and dense enough. If you want to choose roller skates that are bigger than usual, the distance from the front end of the shoe to the inner sleeve is as much as half a thumb (hand). Try to choose a shoe buckle with a lock; Be sure to wear complete protective equipment, including wrist pads, elbow pads, knee pads and helmets. ?
