Jordan Spieth is a creature of habit. If you look at his golf bag, it’s like a time capsule. While other pros swap drivers every time a new carbon-fiber marketing campaign hits the shelves, Spieth clings to what works. This is most evident in his flat stick. For over a decade, he has used the same style of jordan spieth putter grip—the SuperStroke Flatso 1.0—to navigate the most high-pressure greens in the world.
He doesn't just use the model. He uses them until they are literally disintegrating.
There was a famous moment at Bay Hill a few years back where photographers zoomed in on his handle. It looked like it had been through a woodchipper. The outer polyurethane layer was peeling away, exposing the foam underneath. Most amateurs would be embarrassed to pull that out of the bag at a local muni. For Jordan, it was just "broken in."
The Science of the Flatso 1.0
So, why this specific grip? Most SuperStroke grips are known for being round or slightly "pistol" shaped. The Flatso is different. It has a distinct pentagonal profile. Basically, the front of the grip is wide and completely flat.
This isn't just for comfort.
Spieth uses a cross-handed (left-hand low) putting style. When you put your left hand below your right, the geometry of your shoulders changes. A flat-front grip like the Flatso 1.0 allows him to "square" the putter face more easily. His left thumb sits perfectly on that flat surface. This creates a physical reference point that tells his brain exactly where the putter face is pointing.
Modern Tech: Zenergy and Spyne
While Jordan prefers the "feel" of an old grip, he does eventually have to replace them. In 2026, he’s typically seen with the SuperStroke Zenergy Flatso 1.0.
The "Zenergy" line is the latest iteration, featuring something called Spyne Technology. It’s a heavily embossed ridge on the underside of the grip. It acts as a guide for repeatable hand placement. For a guy like Spieth, who relies on a very specific "double overlap" finger configuration, having that ridge to lock into is vital.
The specs are pretty precise:
- Width: 1.16 inches
- Weight: Around 87 grams
- Shape: Non-tapered pentagonal
The non-tapered part is huge. Standard grips get thinner at the bottom. The Flatso stays the same thickness all the way down. This prevents the "twitchy" right hand from taking over the stroke, which is the primary reason most people switch to cross-handed putting in the first place.
Why He Let It Get So Worn
Golfers are superstitious. Jordan especially. He’s gone through massive slumps and incredible peaks, but the putter is his security blanket. A fresh grip feels "slick" to a pro. It’s too tacky. It hasn't molded to the specific pressure points of their fingers yet.
Jordan has mentioned that he likes the "smooth" feel of a worn grip. When the texture wears down, the grip becomes less about the "tack" of the rubber and more about the shape of the foam underneath. Honestly, it’s about removing variables. If a grip feels exactly the same for two years, that’s one less thing to worry about when standing over a 15-footer for birdie.

How to Mimic the Spieth Grip
If you’re struggling with "wristy" putts, trying the jordan spieth putter grip setup might actually help. But don't just slap the grip on and expect to drain everything. You have to understand the mechanics.
- Left Hand Low: If you’re a righty, put your left hand on the bottom. This levels your shoulders.
- The Overlap: Jordan uses a "double overlap." His right index finger doesn't just sit on the left hand; it actually rests in the crease between the fingers of his left hand.
- Light Pressure: Because the Flatso is wider than a standard grip, you don't need to squeeze it. Hold it like you're holding a bird—firm enough so it doesn't fly away, but light enough so you don't crush it.
Common Misconceptions
A lot of people think Jordan uses a "Jumbo" grip. He doesn't. The 1.0 is actually the smallest version of the Flatso series. There is a 2.0 and a 3.0 that are much thicker.
Jordan prefers the 1.0 because he still wants "feel." If the grip is too thick, you lose the vibration of the ball hitting the face. You become disconnected. He’s a feel player who looks at the hole while putting sometimes—he needs to know exactly what that impact felt like.
Another weird detail? He doesn't use much counterbalance. While SuperStroke offers "Tech-Port" weights that you can screw into the top of the grip, Jordan usually keeps it simple. He wants the weight of the head (his legendary Scotty Cameron 009) to be the primary thing he feels.
Your Next Steps for Better Putting
If you want to try this setup, don't go out and buy a 3.0 "fat" grip. Start with the SuperStroke Zenergy Flatso 1.0. It’s the closest thing to what Jordan actually uses.

Once you have it installed, spend at least three weeks committed to the left-hand low style. It will feel incredibly awkward for the first 48 hours. Your brain will want to "flip" the wrist. But if you stick with the flat-front profile of the Flatso, you’ll find that the putter head starts staying online much longer through the impact zone.
Go to a local shop and feel the difference between the Flatso and the Pistol GT. The edges on the Flatso are sharp—they give you "corners" to wrap your fingers around. That's the secret sauce Jordan uses to keep his face square when the nerves start rattling.
