Pros: The wide, flat section on the front of the grips helps fill up a golfer’s hands, which can add stability to their stroke and help relieve tension. The pistol-style backing provides more “reminders” for hand placement than SuperStroke’s round-backed putter grips.

Cons: The grips come to a point in the back that is very noticeable in the fingers. Some golfers will love it, others will hate it. The Flatso (100 grams) and Flatso Ultra (85 grams) are also a bit on the heavy side, which could cause swing weight problems.

Bottom Line: They’re still non-tapered, but the Flatso family has a shape that’s much different than… anything else, really. They come in three distinct sizes that should cover the needs of most interested golfers. While they won’t be as popular as SuperStroke’s round-backed grips, plenty of golfers are still going to dig them.


The Flatso grips build on the platform established by SuperStroke’s extremely popular line of round-backed grips, the Ultra Slim 1.0, Mid Slim 2.0, Slim 3.0 and Flatso 5.0. Like those grips, the Flatso grips are non-tapered, but they have wide, flat section on their fronts that are designed to place goflers’ hands farther apart to help them make a more shoulder-driven stroke.

The back part of the Flatso grips form a pentagon-shape, giving them a pistol feel that many golfers prefer in their putter grip. They come in three different sizes, the largest being the Flatso, which has a 1.7-inch diameter and weighs about 100 grams. The Flatso Mid has a 1.4-inch diameter and weighs 60 grams, while the smallest model, the Flatso Ultra, has a 1.1-inch diameter and weighs 85 grams. All three grips measure 10.5 inches in length, and a 17-inch Flatso “Arm Lock” grip will also be available.

The Flatso and Flatso Mid grips will cost $24.99, while the The Flatso Ultra will cost $19.99. The Flatso 17-inch grip will maintain the company’s 2013 graphics (more on that in the Looks and Feel section) and will cost $29.99. All four grips will hit stores in April 2014.


SuperStroke’s Flatso putter grips are exactly what the company intended them to be: oversized putter grips with a shape that makes them feel much different than the company’s round-backed putter grips.

The wide, flat front sections of the grips helped move their edges into the lifelines of my hands, making them feel more stable on the putter. I also enjoyed the very “feelable” seam on the back of the grip, which served as a nice reminder of where my fingers should rest.


The largest grip in the series, “Flatso,” will most likely be preferred by players with larger hands or by those who want their hands as far apart as possible on the putter grip. For a lot of golfers, Flatso will feel way too big, however, like they’re gripping a pop can. But for some golfers, like K.J. Choi, who has used SuperStroke’s Fatso grip for nearly a decade, it has the potential to kill off the small twitches that can make 3-footers miss the cup.

Most golfers will probably gravitate toward the Flatso Mid and Flatso Ultra grips, which are a much more manageable size. Like SuperStroke’s “Slim 2.0″ round-backed grip, the Flatso Mid is a nice middle ground between a conventional-size putter grip and the company’s largest grips. It gives a feeling of splitting the hands without making them feel like strangers.

The Flatso Ultra, played by Jordan Spieth, will probably be the model liked by most better players because of its more conventional size. But it’s still a very unique-feeling grip thanks to its firm underlisting, which maintains the grip’s crisp pentagonal lines that act much like a reminder rib in a club grip.

Personally, I did not care for the Flatso Mid or Flatso Ultra as much as the Flatso, because I could not seem to make the three distinct ridges on the back of the grip fit properly in my hands. But I have very large hands, and know that my preferences will be in the minority.

The Flatso (100 grams) and Flatso Ultra (85 grams) are a little heavier than most models, which gives them the counterbalancing effect that is trending right now in the world of golf. The Flatso Mid, 60 grams, should not affect swing weight on most golfers’ putters.

A note about installation: The Flatso grips were easy to install and remove using the “blow on method.” All three versions of the Flatso were installed with one piece of build up tape and stayed secured throughout the testing process. Aligning the grip was easy and hassle free thanks to the wider flat sections of the grips.

Looks and Feel

SuperStroke’s “CrossTraction” grip texture is used on all three Flatso putter grips. It debuted on its 2013 line of putter grips, and was well received for its improved performance in the rain and hot, humid weather. What’s best about the new grip texture is that it did not change what originally attracted most golfers to SuperStroke’s putter grips in the first place, the tacky polyurethane material that balances a soft feel with a firm underlisting.

In 2013, the company launched the Flatso grips with “split graphics” that were a slight departure from the company’s cleaner design on its round-backed grips. For 2014, the cleaner graphics have returned, with a dual-color thumb-placement design that’s new for the company’s retail grips.

2014 Flatso graphics


Each of the 2014 grips have their own unique colorway, with the Flatso available in white/black/green, the Flatso Mid available in white/black/red and the Flatso Ultra available in white/black/silver. The new graphics will help differentiate the models being used on the professional tours, and will also make the grips appear smaller because of the removal of the center line on the middle of the flat front section.

The Takeaway

The new Flatso series of grips are a great addition to the company’s product line. They’re a niche product, and for that reason they won’t sell like the company’s original round-backed grips. But players who like them are going to love them, growing SuperStroke’s notoriety in the serious golfer community.

  1. Agree need all black the white gets dirty and makes slippery.
    I’ll bet to get you to to replace not just for adverticing.
    Scotty Cameron will copy it and make it better…

  2. I used the flatso 1.4 and felt really good but didn’t live up to the hype. I tinkered with it and then turned the flat side toward the target and what a difference. A completely different feel and now I’m averaging 27-30 putts around instead of the normal 32-36 putts. Anything 10 feet and in are automatic.
    Give it a try….

  3. Got the Super Stroke Flatso Ultra now on my Scotty and it grips nice though the grip appears bit slithery at first. Had the Scotty Pistolero for about two years and I am now keen to see how the Ultra performs. Like the fact that this is slightly wider and fairly flat on the top than the usual putter grips. I believe we will become friends for a long time.

  4. It’s what you do not how you look doing it! Had one put on yesterday and is 10x better than the Standard super stroke, the flat front keeps you in contact with the position of the club face throughout the stroke. Switched from a std ultra to flatso mid

  5. Have not actually put my hands on these but I like the idea. I have a Slim 3.0 on my putter and it is just a little to big and I think that this may be my solution…

  6. I have the fatso 85(I bought mine well before duff won with it!) on my phil mickelson prototype putter and I love it, the only problem I had was it made the head feel too light, so I put 20 grams of lead powder down the shaft. ive never been steadier. I also installed the flatso ultra (the 1.4″) diameter grip on my playing partners Wilson 8882 blade putter and he has shaved at least 4 strokes off of his game, I might get one for myself even, its like the perfect size, especially with the rib. the grip is the same every time. for people with Arnold palmer sized hands, its a no brainer. imagine if the king had a grip that big, those speedy greens he hated would have been bit easier

  7. I have hooked putts my whole life, generally conquered the problem but still rears it’s ugly head occasionally.

    I tried one of these after Duff won the PGA, had it on my favourite putter for a month or so and never hooked a putt, ever.

    Missed all sorts of putts right instead, went back to my standard grip, didn’t help me.

  8. Kadin,

    Thank you for the comprehensive review. I am currently using a Super Stroke 2.0 grip and will give the Flatso a chance in the spring. I too wish the company would provide an all-black grip as the mostly white design looks awful in a short period of time.

    • my fatso 85 is white with black accents. and your right. it has a nice yellow tint too it now. imagine if I was a smoker, it would be even worse! but maybe more tacky from the tar

  9. Reverse the color scheme. Mostly black, some white and some of the “bright” color. Viewers would still know they are SS and users would get what they want. I actually have white iron grips but haven’t gone to SS because too much is going on with all the logo and everything else.

  10. Definitely a fan but two things really stick out. One: The release on the ultra has been pretty annoying (dates, color, communication). Two: The colorway is horrible, I would like to see one user that has been able to get more then one season out of these grips without it looking gross. We pay big money for these, and unlike the pros we like our gear to last/look good for more then 4 rounds. It’s time to offer your loyal customers some options.

    I totally understand the marketing concept of making the product stand out, but now that everyone knows what super stroke is. Give us some options! Please! Other companies are now eating into the market share due to color choice alone… Wake up already! I guess there just too busy counting money to listen. A real shame.

  11. Loving the Flatso Mid I put on about 2 months ago. Never was really into the SuperStroke grips, but the new shape of the Flatso really fit my hands very well and fit my stroke. Great grips.

  12. They don’t have to make solid colors or less busy graphics. They don’t care that customers are clamoring for better coloring because they are the only ones who make it.

    Pretty disappointing they don’t care.

  13. Nice review Julia, I mean Kadin! I would like to see the grips come in a solid, dark color. The problem with white grips is they get dirty very quickly. I clean my grips regularly, but still…
