Hockey stop multi-line roller skate and wheels for use therewith

A roller skate comprising:

• a center line of wheels, having a first coefficient of friction;
• a first outer line of wheels, having a second coefficient of friction, wherein said second coefficient of friction is higher than said first coefficient of friction;
• and
• a second outer line of wheels, having a third coefficient of friction, wherein said third coefficient of friction is higher than said first coefficient of friction.

A roller skate comprising:

• a first line of wheels, having a first coefficient of friction;
• a second line of wheels, having a second coefficient of friction, wherein said first coefficient of friction is not equal to said second coefficient of friction;
• and,
• at least one of said first and second line of wheels are asymmetrical in cross-section.

A method of improving performance of a roller skate comprising:

• providing a foot attachment device;
• attaching to the foot attachment device a first line of wheels, having a first coefficient of friction;
• and
• attaching to the foot attachment device a second line of wheels, having a second coefficient of friction wherein said second coefficient of friction is unequal to said first coefficient of friction.
