The contact surface of skates is mostly rubber or PU pulleys, while the ice contact surface of skates is metal “skates”; in addition, roller skating requires higher sports equipment, such as helmets, knee pads, elbow pads, hand guards, etc. There are all equipment applications, and the most commonly used protective gear in skating is knee pads.
Although roller skating and skating are in the same line and have similarities at the technical level, the details of the movements in starting, accelerating, shifting the center of gravity, braking, and trick movements are quite different.
Roller skating and skating have three basic sports: figure, ball and speed skating. At the same time, roller skating also derives sports such as flat style, figure braking, downhill, and free roller skating, while skating does not have so many sports. The categories and gameplay. Roller skating learning and training venues abound, as long as there is a hardened field; the basic movements and physical training of skating can be completed on an ordinary hardened field, but the sliding practice must be completed on the ice surface.
The wheels of the skating wheel manufacturers choose the right wheels according to the purpose of the shoes. The size of the flat wheel is generally 74MM and 76MM wheels, and some are 76MM and 80MM, and the hardness is 85A. The wheels of speed skating shoes are generally 4×100 in size.
As for other types of shoes, the requirements for wheels are more clear. The hardness of the wheels of extreme shoes is very large, and the size of the wheels is very small, which seems to be 52MM and 56MM. In terms of material, the wheels of skates are made of TPU. This material has strong wear resistance and slight elasticity, which can effectively reduce the impact of vibration on the body.
