Skating

skating" can be broken into three categories: roller skating, inline skating, and ice skating. 

Roller Skating

Roller skating involves gliding over a smooth surface on roller skates, which are specially designed boots with two wheels at the front and two at the heel.  Roller skating can be enjoyed outdoors or at indoor roller rinks.

Inline Skating

Inline skating is a popular recreational activity where the skater glides on lightweight boots with three to five wheels attached in a line.These skates were comprised of a metal frame, urethane wheels, and a heel brake.  Olsen later founded Rollerblade, Inc., producing in-line skates for general recreation.

• Ice Skating

In the sport of ice skating, skaters glide across ice on ice skates; special boots attached to steel runners.  Ice skating may be performed in indoor or outdoor rinks, and on frozen lakes, ponds, rivers, or streams.  The sport is most prevalent in countries with long, cold winters, although the indoor rinks have made ice skating popular in warmer areas as well.
