But because of the different size of each wheel, this shoe can only slip forward. In 1863, the American James invented a pair of four-wheeled skates with side-by-side wheels, which could do various movements of turning, forward and backward, which is now the most widely circulated roller skate.

At the end of the Middle Ages, skates spread from Norway to all parts of Europe, and the materials used to make them expanded to include wood, animal bones, or iron. After the invention of refrigeration technology, the world's first artificial ice rink opened in London in 1842.

In 1854, Canadian Forbes invented a skate that was fastened to the sole of a shoe by a metal pin. There are no straps or buckles, and there are springs and levers between the boot and the skate, so it only takes a minute to load the skate on skates of any length. Forbes' improved skates were so successful that he set up a factory in the New Scotland province to produce them.

There are three types of skates, roller skates, roller skates, and skate shoes. Mihu.

First, roller skates:

1. Double-row roller skates: Professionally known as fancy roller skating shoes, with two wheels at the front and back, and a brake in front of the front wheel, also known as an ice spotter, so as to facilitate figure skaters to make some ice jumps.
