Originally for rink-hockey for small sizes but also suitable for roller derby, hiking or skatepark.
As long as you need good, secure support on your skates'brakes. To block in derby, brake hard when hiking or lean on it in a bowl or ramp on the modules.

The reduced size will allow you to quickly leave the flat surface so that you brake effectively.
