What is the difference between roller skates?

There are different types of roller skating. Shoes are different because of their different functions. For example, extreme shoes and patterned shoes are very different. Pinghua has low requirements for equipment, generally four wheels are selected, and the upper is preferably soft and easy to make movements, which can be high or low. That kind of hard plastic high-top shoes is suitable for beginners.

If you need something cheap, you can buy Zudis, Qu Zhi, Migao, Chicago, and models between 300 yuan and 500 yuan.

The price is higher between 500 yuan and 700 yuan, and the professional one is more than 2,000 yuan. Unless you are an enthusiast, there is no need to invest too much.

Body: The shell of roller skates can prevent external impact and protect feet. Generally, shoes with buckles are more convenient to wear; Those who tie shoelaces will be closer to their feet, but it will be more troublesome to put them on and take them off. Generally, better roller skates are designed with straps and buckles. Ordinary roller skates have inner boots, which can cushion the friction between the foot and the shoe shell, thus protecting the foot and making the skin not easy to scratch and blister. A good shoe body should be strong enough, the sponge should be thick enough and the density should be high enough.

Underframe: Underframe is the structure connecting the wheel and the shoe shell. The toughness of the underframe system is the main factor that determines the service life of roller skates. There are usually different types of underframe designs, some thicker and some thinner. The underframe is usually equipped with four wheels, but there are also small underframes with three wheels and speed shoes with five wheels. Aluminum alloy chassis is better, because aluminum alloy chassis is hard and not easy to deform, but it is more expensive.

Wheels: Wheels must be highly elastic, not plastic. It is best to choose polyester materials, that is, rubber tires, which are suitable for various venues and conditions. Rubber wheels are soft and elastic, while plastic wheels are hard. You can try knocking on the ground to feel the sound, and you will find that the sound of plastic wheels is much sharper and easy to slip. Some roller skates are equipped with hexagon wrenches to tighten the wheels.

Size: In addition to the quality of each part of the shoe, we should also pay attention to the size of the foot. Experts suggest that if you buy the usual size, you must wear it yourself. Must not be too big, as long as it doesn't feel tight. Generally, the shoelaces are tied. When the calf is vertical to the ground, the distance between the front end of the foot and the inner sleeve of the shoe is as much as half a thumb (hand). Too big shoes are unsafe. Nowadays, many shoes have telescopic function, and roller skates can be enlarged with tools.
