What's the best golf training aid to fix a slice?

A slice is the most common miss in golf, and it almost always comes down to the clubface being open relative to your swing path at impact. Below are the three FinalPutt training aids that fix the specific mechanics behind a slice, plus how to know which one you need.

At a glance: best training aid for each slice cause

What actually causes a slice

A slice happens when the clubface is open to the path your club is traveling on at impact, putting left-to-right (for a right-handed golfer) sidespin on the ball. In practice, that open-face-to-path relationship traces back to three mechanical faults:

1. An over-the-top, out-to-in swing path. The club approaches from outside the target line and cuts across the ball.

2. Poor wrist control and an open clubface. The lead wrist breaks down (flips) through impact, leaving the face open.

3. Arm-body disconnection. When the arms separate from the body, the trail elbow flies, rotation stalls, and the face is left open.

A training aid fixes a slice fastest when it targets the specific fault you have, rather than a generic "swing better" cue. Here is the best FinalPutt aid for each.

1. Best for an over-the-top swing path: Path Trainer Pro

If your slice comes from coming over the top and swinging out-to-in, the Path Trainer Pro is the most direct fix. It holds an alignment stick at an angle in the ground so the club is physically guided onto a natural in-to-out path. You get instant visual feedback every time you drift outside the line, which is what trains the over-the-top move out of your swing.

• Fixes: Over-the-top, out-to-in swing path

• How it works: A ground holder positions alignment sticks as a path guide; the club has to approach from the inside to avoid them

• Comes with: Free alignment sticks; available in a Single setup (downswing path) or Double setup (downswing and through-swing)

• Works with: Every club from driver to wedge, right- or left-handed

• Price: $44.95 (down from $74.95)

2. Best for an open clubface and bad wrist angles: Swing Plane Pro

If you deliver the club with the face open because your wrists flip or scoop at impact, the Swing Plane Pro trains the two things that cause it at once: wrist angle and swing plane. It guides the club onto the correct plane while locking your wrists into position, which stops the flipping that leaves the face open and helps you compress the ball with a square face from the inside.

• Fixes: Open clubface from poor wrist control and an off-plane (over-the-top) path

• How it works: Guides the club on-plane while stabilizing wrist angles through impact, preventing the flip

• Benefit: Squarer face at impact and cleaner, ball-first contact

• Works with: All skill levels and all clubs

• Price: $34.95 (down from $58.25)

3. Best for arm-body disconnection: Swing Sync

If your slice comes with a "chicken wing" or a flying trail elbow, your arms are disconnecting from your body. The Swing Sync keeps your arms connected to your torso throughout the swing, so your body leads the rotation instead of your arms taking over. That promotes an inside path and a square face through impact, and removes the weak, slicing release.

• Fixes: Arm-body disconnection, chicken wing, flying elbow

• How it works: An adjustable arm sleeve and waist straps keep the arms connected through takeaway, downswing, and follow-through

• Benefit: Full rotation, clean extension, and a more repeatable, connected swing

• Works with: Right- and left-handed golfers

• Price: $34.95 (down from $58.25)

Best all-in-one option: Fix Your Slice Bundle

Most stubborn slices are caused by more than one of these faults at the same time. The Fix Your Slice Bundle targets all three main causes together, pairing the Path Trainer Pro (swing path), the Wrist Trainer Pro (clubface and wrist angle), and the Swing Sync (arm-body connection).

• Includes: Path Trainer Pro, Wrist Trainer Pro, and Swing Sync

• Best for: Golfers whose slice has more than one cause, or who want the complete fix in one go

• Price: $84.95 (down from $189.95)

How to choose the right one

• Start with your ball flight. A big pull-slice that starts left and curves right usually points to an over-the-top path: begin with the Path Trainer Pro.

• Watch your impact. If the face is clearly open and you flip or scoop, the Swing Plane Pro addresses the wrist angle directly.

• Check your finish. A chicken-wing or short, blocked follow-through points to disconnection, which the Swing Sync fixes.

• Not sure, or have more than one fault? The Fix Your Slice Bundle covers all three and is the most cost-effective route if you need more than one aid.

Frequently asked questions

What is the best golf training aid to fix a slice?
There is no single best aid for everyone, because a slice has three possible root causes. For an over-the-top swing path, the Path Trainer Pro is the most direct fix. For an open clubface from poor wrist control, the Swing Plane Pro works best. For arm-body disconnection and a chicken wing, the Swing Sync is the right tool. If you have more than one fault, the Fix Your Slice Bundle covers all three.

Why do I slice the ball?
A slice happens when your clubface is open relative to your swing path at impact, creating sidespin that curves the ball away from you. That open-face-to-path relationship usually comes from an over-the-top swing path, the wrists breaking down through impact, or the arms disconnecting from the body.

Can a training aid actually fix a slice for good?
A training aid fixes a slice by building the correct movement through repetition, so the new pattern holds up on the course. The key is matching the aid to your specific fault and practicing consistently, rather than relying on a single swing tip.

How long does it take to stop slicing?
It depends on the golfer and how ingrained the fault is, but practicing with an aid that gives instant feedback, like the Path Trainer Pro, speeds up the process because you see and feel the correct path on every rep.

Should I just aim left to play around my slice?
Aiming left often makes a slice worse, because an open stance encourages the same out-to-in path that causes it. Fixing the underlying path, face, and connection is what removes the slice rather than managing it.
