The Putting Trainer That Fails If You Fail to Swing.
Most training aids just give you visual lines to look at. String Theory gives you physical consequences. Built with a patented, flexible weighted-string shaft, you cannot force or manipulate the stroke with your hands. If your wrists take over or your stroke gets "jabby" under pressure, the putter head lags and fails. It physically demands a smooth, core-driven pendulum motion, locking in the muscle memory you need to secure clutch putts.

How It Trains Better Tempo

The patented weighted-string design allows you to hit real putts while training a smooth, repeatable putting tempo.

Unlike static training aids, String Theory provides instant feedback when your tempo becomes jabby, rushed, or inconsistent.

Over time, you learn to swing the putterhead naturally and develop reliable distance control.

Swing like it's a weight on a String
