Best use will determine the performance based on the skate specifications. Some wheels are better for urban and aggressive skating while others are designed for distance and marathon trainers.

 

Aggressive - Generally smaller wheels so not optimal for distance skating.

 

Roller Hockey - Generally a medium wheel size; wheel size may vary on the frame to maximize performance. Softer durometer for maximum performance on indoor surfaces.

 

Recreational - Medium sized wheels to help handle the bumps and uneven surfaces of neighborhoods and parks.

 

Performance - A larger wheel; ideal for longer distances, training and exercise.

 

High Performance - Larger wheels for maintaining high speeds and designed with features to truly maximize performance. Ideal for long distance skating, marathons, training and tons of speed.
