When doing roller skating, the most important equipment is roller skates. Roller skates can be divided into two categories according to their structure: double row roller skates and single row roller skates.

In fact, there are also professional and non-professional roller skates.

So which one is better for a friend who loves roller skating? If you are a beginner, how to choose roller skates? Let's learn more about it.

The difference between professional and non-professional roller skates:

There are four main differences between professional roller skates and special roller skates. Take extreme single row roller skates as an example:

1. Wheels at the bottom of the shoe: The wheels of non-professional pulleys are hollow, with regular small holes visible on the shaft, and the bottom of the wheel is often round.

On the contrary, for professional grades, the wheel is solid and the bottom of the wheel is flat, which can withstand larger Impact, complete a lot of difficult jumps.

2. Whether there is a groove in the middle of the sole: This groove is used when the slider is fitted with the iron rod. Professional-grade pulleys must have grooves.

3. The "beam" of the sole: the thick and thick beams are professional roller skates, and the weak "beams" are non-professional roller skates.

When wearing these shoes, you should be careful not to do impact actions such as jumping, otherwise the shoes will break and cause danger. .

4. Weight of shoes: Professional roller skates are heavy because many parts are solid and made of very sturdy materials.

The key points of attention when purchasing roller skates:

1. Shoe shell

Generally speaking, shoe shells are divided into soft shoe shells and hard shoe shells. For beginners, it is recommended to buy hard shell shoes here.

First, the hard shell of the shoe can better protect it and prevent collision and injury. Second, the hard shell can provide better support for the ankle and prevent the ankle from twisting.

2. Inner liner

The inner bladder is in direct contact with the feet, so its selection is also very important. A good liner must have a certain thickness to better absorb shock.

At the same time, it also provides good comfort and breathability. The inferior liner has poor comfort and wrapping, and it is easy to harden after a long time of use.

3. Tool holder

The knife holder is an important part connecting the shoe body and the wheel. Generally speaking, a hollowed-out aluminum alloy tool holder is good, which can provide sufficient strength and at the same time minimize the importance of shoes.

4. Wheels

There are generally three kinds of materials for wheels: plastic, resin and polyester. Plastics and resins are relatively cheap, but the wear resistance and heat resistance are poor, and the grip is also average.

Therefore, it is recommended to buy polyester wheels if possible. The polyester wheel is wear-resistant, and has good elasticity and grip, which is necessary for long-term sliding.

The parameters on the wheel, such as 80A 70mm, indicate the hardness in the front, and the diameter of the wheel in the back.

The hardness is generally around 78A. Size: 70mm for children, 90mm for adults is more suitable for beginners.

5. Bearing

The bearings on the wheels determine the flexibility of the shoe. The smoother the bearing, the less resistance the better. The large resistance not only affects the movement when sliding, it is easy to deform, and it is easy to make the feet tired.
