Roller Blades can be used for a few different things today. Most oftern they are used for just recreational skating either for exercise or to get form point A to point B. They come with a wheel that is generally good on either and indoor or outdoor surface, skating on them outdoors just wears them down quicker compared to inside. Another activity these skates are used for is inline hockey, they can be used for this sport in the beginning but you may want to get actual hockey skates for the protection part of the sport. Roller blades are great for learning to skate and learning the balance of things while on the track.
