This Bont inline skate brake works really well for skaters who love speed skates but miss having a brake that they are used to using on their rollerblades or recreational skates. Most rollerblades and recreational skates come with a brake so skaters get familiar with using it to come to a stop. Speedskaters will normally use a snowplow walking technique to come to a stop but until you can learn how to do this, a heel brake is a good idea. The rubber on this brake is long-lasting and replaceable.
