No Single Stop Works Everywhere: Build a Tool Belt

No one stop covers wet ground, a narrow path and real speed. Linear stops — heel brake, T-stop — suit tight spaces; rotational stops (soul slide) let you steer away from a hazard while braking. A certified coach's order: heel brake, plough and stepping plough, T-stop, turn and lunge stops, soul slide. She starts beginners on the heel brake; I took mine off once comfortable. From ICP-certified coach Asha Kirkby; note from me, Cass, a non-professional street skater.
The useful question is not which stop is best. It is how many stops you have, because wet ground, a narrow path and real speed are three different problems and no single technique answers all three.
Linear stops keep you travelling in a straight line. The heel brake and the T-stop belong here, and they are what you want in a tight space where swinging sideways would put you into something.
Rotational stops let you steer while you brake. A soul slide turns you away from whatever you are trying not to hit, which is a different kind of safety from simply slowing down sooner.
A certified coach's order to learn them in: heel brake, then plough and stepping plough, then the T-stop, then turn and lunge stops, and the soul slide last. She starts beginners on the heel brake, and she is right that it is the easiest one to reach first.
Where my own experience differs, and it is a difference of stage, not of principle: I took my heel brake off once I was comfortable, because it started getting in the way in turns. That says nothing about whether a beginner should start with one — she should. Technique from Asha Kirkby of Skatefresh, an instructor certified by the Inline Certification Program. She teaches inline skating, and that is the discipline this page is about. Personal account from Cass, a non-professional street skater — not a coach, and this page does not pretend otherwise.
