Heel brake still shaky? The plow stop slows you down at low speed using your inside edges — both feet stay on the ground. An addition, not a replacement.
Your heel brake still feels shaky, but you want a controlled way to stop at low speed? Here's the honest answer: learn the plow stop as well. Open your legs, push your heels outward, and brake on your inside edges — without lifting the wheels off the ground even once.
Remember the wedge turn from skiing? It's the exact same movement, just on wheels. The plow stop slows you down at low speed — as a beginner, it won't be enough for more speed, let alone on a slope. Still, for flat paths and your first weeks on skates, it's gold, because you never have to balance on one leg to use it. It doesn't replace the heel brake — it adds to it.
Before braking from full speed, train your edge control in isolation. Ride swizzles (also called lemons or the "rocking horse"): open your legs outward from the V-position, then pull your toes back together. That's exactly the feeling you'll need in a moment for braking pressure.
Glide forward slowly, drop deep into your knees ("ready stance"), and open your legs well past shoulder-width — your track should look like a diamond. Keep your weight centered.

At the widest point of the diamond, turn your toes inward and actively push your heels outward — that's the plow. Keep your thighs tense: your toes can get close, but never touch or cross — otherwise you'll trip instantly.
Now press onto your inside edges while holding the plow stance. Hips slightly back, weight behind the skates. The deeper your knees, the more pressure, the faster you stop.
The plow takes strength in your thighs. The most common fall: your toes run together and you tip forward over your skates. Stay low, hips slightly back, weight behind the skates — and remember our rule of thumb "Oh no, go low!" For your first few tries, practice slowly near a wall or railing you can briefly lean on if needed.
Notice your braking power fading at slightly higher speed? Try the stepping plow: instead of holding rigidly in the diamond, take quick, alternating steps from side to side. This resets your braking pressure dynamically and makes it easier to stay balanced — basically the difference between a car parked with the brake locked and one rolling stop-and-go. Get comfortable with this variation and you're already halfway to the feel you'll need for the T-stop.
There's no fixed number. As a beginner, the plow slows you down at low speed; for more, it usually isn't enough. If you keep rolling despite the plow, that's your signal: for more speed, the heel brake is your tool. Experienced skaters can control faster rolling with the plow too — you'll get there with time.
Pull your toes together less aggressively and always leave a small gap. If the front wheels touch, both skates lock up instantly and your upper body tips forward uncontrolled. Practice the plow stance slowly while standing still before using it in motion.
They complement each other, but most people start with the heel brake because it still works at higher speed. The plow stop is worth adding as a second technique for low speed — it can't replace the heel brake.
As a beginner: no. On a slope your speed builds quickly, and an unpracticed plow isn't enough for that. At higher speed or on slopes, the heel brake is your tool — and you avoid slopes completely until it's solid. Experienced skaters do control slopes with the plow too, but that's a later step.
That's normal, and actually a good sign: those muscles (your adductors) hold the edge pressure in the split stance and get worked in an unfamiliar way for most beginners. Mild soreness after your first few sessions fades within one to two weeks of regular practice.
