Training Aids to Fix a Slice
A slice has two real causes: an open face and an out-to-in path. These aids and drills address the causes — not the ones that just paper over the symptom.

A slice isn’t a mystery, and fixing it isn’t about buying the loudest gadget on the rack. A ball that curves hard to the right (for a right-hander) has two real causes, and every genuine fix targets one or both of them: an open clubface relative to your path at impact, and an out-to-in (over-the-top) swing path. Aids that address those help. Aids that only mask the result — a low-spin ball, a heavily offset club — can straighten the flight without ever teaching you to stop slicing.
First, work out which cause is yours
Most slices are a bit of both, but usually one dominates. If your ball starts left of target and curves back right, your path is out-to-in — the classic over-the-top move. If it starts more or less on line and then peels right, the face is the bigger culprit. The cheapest way to see your path is a Divot Board, which shows an out-to-in mark plainly; for the face, an aid that gives feedback on face angle is what you want. Diagnose before you buy.
For the open face: The Hanger
The face is the larger cause of most slices, and The Hanger targets it directly. It clamps to your iron and presses your lead forearm the instant the face opens through the swing, so you get immediate physical feedback on a square versus open face — the exact fault behind the curve. Because it trains clubface awareness rather than forcing a position, the feel transfers when you take it off. It’s the aid on this site most specifically aimed at the slice’s main cause.
For the over-the-top path: the alignment-stick gate
You don’t need to spend much on the path fix. The gate drill from our alignment stick drills— a stick set just outside the ball that your club must avoid on the way down — gives you an instant, physical check against coming over the top. Clip the stick and you came out-to-in; miss it and your path is shallowing correctly. It’s about the cheapest slice fix there is, and one of the most effective because the feedback is impossible to fudge.
A useful supporting cast
A connection aid like the Tour Striker Smart Ball or Impact Ball can help indirectly: many over-the-top moves start with the arms disconnecting from the body at the top, and keeping them synced encourages a shallower path. It’s a supporting drill, not the main event — use it alongside a face or path tool, not instead of one.
What to be sceptical of
Two “fixes” that don’t actually fix the slice. First, rigid plane harnesses that force the club onto a path: they hide the fault while they’re on and it returns the moment they come off. Second, and this one’s a trap — adding swing speed. A speed trainer like SuperSpeed is a genuinely good tool for distance, but if your face and path are off, swinging faster makes the slice curve more, not less. Fix the cause first; add speed once the ball is starting straight. And by all means play a straight-flying, low-spin golf ballwhile you work — just know it’s easing the symptom, not curing it.
The honest bottom line
Diagnose the dominant cause, then train it with a feedback tool: The Hanger for an open face, the alignment-stick gate for an over-the-top path, a connection ball as support. That combination costs little and addresses the slice at its source. Skip anything that promises to fix it in a week or does the swing for you — a slice is unlearned with honest reps and honest feedback, not bought off.
