Inside the Stroke #2: The Shaft – The Spine of Your Stroke

People love to talk about the head or the grip. But in between lies the true spine of your stroke: the shaft.It’s not just a stick – it shapes how you feel the ball, how you see the line, and how your putter behaves.

1. What does the shaft really do?

A putter shaft defines:

• The lie angle

• The offset, which changes how you see the face

• The material, influencing stiffness and feedback

• The shaft attachment point (center vs heel), affecting stroke dynamics

At RUNNER, the shaft is fully configurable to fit your unique stroke style.

2. Materials and feel

• classic steel shaft – stable and forgiving

• KBS GPS – engineered for putting, premium feel and responsiveness

• Stiffness matters:

  • Stiffer = sharper feedback

  • Softer = smoother sensation

3. Offset: what does it change?

Offset means the shaft sits slightly in front of the face.

• More offset = hands ahead, more control, less rotation

• No offset = cleaner visuals, more natural release

With RUNNER, you can choose the offset that matches your eye and wrist action.

4. Center shaft or heel shaft?

• Center shaft: better for straight-back strokes, symmetrical feel

• Heel shaft: traditional setup, ideal for arcing strokes

And with RUNNER, you can test both during fitting.

Real story

A player with a straight stroke used a heel-offset shaft. Customizable by material, size and color. She was constantly manipulating the face.→ Switched to a center shaft, no offset. Her stroke stabilized, confidence came back.

The shaft is not neutral.It affects your setup, your timing, your confidence.

At RUNNER, we make sure the shaft fits you – not the other way around.
