Inside the Stroke #1 : The ergonomic base of the putter

Place a putter on the ground and take a look.

Does the head sit flat? Do you feel naturally aligned?

If the answer is no… the issue may not lie in the head or the shaft.

More often than not, it comes down to the base – an underrated but crucial component.

What exactly is the “base” of a putter?

At RUNNER, the ergonomic base is the link between the head and the shaft.It plays a key role in:

• Connecting the head to the shaft

• Defining the shaft position (center or heel)

• Setting the lie angle

• Ensuring a stable, neutral contact with the ground

• Accommodate the putter's sight.

Why does it directly affect your putting?

A poorly fitted lie means the head sits awkwardly at address. As a result:

• Your alignment angle is distorted

• Your visual perception of the line is off

• Your impact becomes unstable – and your stroke compensates

A well-fitted base, on the other hand:

✅ Places you in a natural, balanced posture

✅ Frees your stroke from compensations

✅ Keeps the head square both at address and through impact

Designed to adapt to the player – not the other way around

RUNNER bases are:

• Adjustable, depending on the model

• Made of aluminum (RUNNER Standard)

• Compatible with all head types (Original and Pro)

• Modular and easy to switch during fittings (no tools needed)

Real case

During a RUNNER Expert fitting, a 1.78m player used a 35" putter with a standard lie.The head was subtly tilting toward the heel → leading to repeated left misses.By adjusting the base (lie + shaft attachment), the head aligned naturally.

Result: improved consistency, fewer misses – from the very next round.

Putting doesn’t start at impact.It starts with how your putter sits on the ground.

And that’s the job of the ergonomic base.
