Roller skating is a popular activity enjoyed by people of all ages. The basic concept is to use roller skates to glide on a smooth surface. Roller skating can be done on either hard or soft surfaces, and it's a great way to get your body moving and achieve some cardio fitness. Some beginners find roller skating to be challenging and frustrating, but with practice it can become extremely rewarding.

There are many different types of roller skates available on the market today, catering to different needs and abilities. Here are the main types of roller skates:

1. Inline skates are the most common type of roller skate, and they're designed for general use on both hard and soft surfaces. Inline skates typically have four metal or plastic wheels that are attached to a pair of inline bearings. You put your feet into the shoes at the front and push off from the ground with your heels, using your arms to steer.

2. Freestyle skaters use these skates for tricks and stunts, as well as for skateboarding. They have five or six larger wheels that give them more stability when performing tricks or jumps. 

3. Rollerblades are designed specifically for skating on hard surfaces like concrete or asphalt. They have two large blades that sit on each foot, with an enclosed handle that you hold in your hand. You use your arms to move the blades back and forth, providing power to glide forward. Rollerblades are less common than inline and freestyle skates, but they're becoming more popular as they're easier to learn and provide a more unique experience.

If you are looking for a more specialized type of skate, you may want to consider buying a pair of custom-made roller skates. These types of skaters can be made from any type of material you want, so you can find the perfect pair for your unique needs.
