The key to putter fitting? Know your roll
This is the second installment of a four-part series from Modern Golf on putter fitting and the Quintic System.
Find a busy practice putting green, and it’s almost guaranteed that you’ll see at least a few golfers obsessing over the motion of their putting stroke. They’re usually the ones who are using some kind of training aid to help them groove their stroke in a certain way.
For many golfer, it can be time well spent. But what they might not know is that the way their putter moves is only half the equation to good putting. Did you know that two putts with the same clubhead speed can travel significantly different distances? Did you also know that most golfers actually do a good job of consistently swinging the putter through at their desired speed? So why do so many golfers have problems with their distance control? The other half of the equation is controlling what is called their ball roll.
How do golfers control how their ball roll? How should the ball be rolling? It is a very difficult question to answer without using high-speed cameras and motion capturing. Using a system called Quintic, we provide golfers the knowledge and data they need to putt their best. Understanding this data will improve your game.
The image below shows what an ideal 8-foot putt looks like on our Quintic System.
Forward Rotation
As you can see, the ball instantly started to rotate forward off the putter face. A ball that has negative initial ball roll, or “backspin,” will lose speed and can deflect offline. Having the ball rotate forward off the face will give players better distance control with their putts because the ball will lose less energy and stay on its intended line longer. This will aid the ball in rolling over debris and other imperfections on the green such as ball marks, spike marks, etc.
Having anywhere from +25 rpm to +50 rpm initial ball roll is ideal. Any higher and the ball will roll out longer because it will be carrying more momentum. This can make downhill 5 footers scarier than they already are. With an rpm under +20 rpm, the ball doesn’t carry as much momentum to the hole.
Launch
The ball was launched at about 1.75 degrees. An ideal launch angle on most greens is between 0.75 degrees and 2 degrees. Much like a driver, controlling launch has a big influence on how far the ball will travel. That is because on the green, a ball will sit in a small depression as a result of gravity. The ball needs to be launched out of this depression — and not too high or too low. Optimal launch should change depending on the blade length of the grass and the type of putting surface. On lush greens with a longer blade length, the ball will sit in a deeper depression. On firm greens with a short blade length, the ball will not sit in such a deep depression, and for that reason not as much launch is required.
The image below shows what happens to a putt that has a launch angle that is too high.
Zero Skid
Minimal skid is ideal. On a well struck putt, there should be less than 10 percent skid for the total distance the ball travels. So on an 8-foot putt, ideally there should be less than 10 inches of skid (see first image). Once “zero skid” occurs, the ball starts rolling on top of the grass smoothly. When there is too much skid, the result is a loss of distance and ball speed. Every time the ball bounces and strikes the putting surface it loses energy — energy that has been factored into your putt for speed and distance. These putts tend to come up short and offline, and this often happens with long putts or lag putts.
Below are images of a “dew board.” The board simulates putting through an early morning dew where it is easy to see launch and skid. There are two visible lines on the board. The putt that has a flat and consistent line has optimal launch and minimal skid. The putt that looks dotted or chattered has launched too high, increasing the zero skid parameter. The dots are where the ball has struck the putting surface and continues to hop until it reaches zero skid.
Every putt, at some point, reaches zero skid. Reducing the amount of time it takes for the ball to reach zero skid will ensure that the ball will lose minimal energy and carry more momentum to the hole.
Impact Ratio
This refers to how efficiently clubhead speed is converted into ball speed. For all of those Trackman users out there, this is the same as smash factor. It is a simple calculation: ball speed divided by clubhead speed. Controlling the speed that the ball comes off the face is crucial. This is achieved when the center mass of the club head makes contact with the center mass of the golf ball. Any off-center strike results in a loss of ball speed and face deflection, causing the ball to roll offline with less speed.
We’ve all hit full shots that weren’t solidly struck and they come up short of our target. The exact same thing happens when we don’t hit a putt solid, but it’s much harder to feel the mishit because the clubhead speed is much slower through impact with a putter. This is where most golfers struggle.
The face of the putter also needs to be square to the path of the club. Otherwise, you’ll see a glancing blow that also reduces ball speed. The type of putter a player uses also has an effect on ball speed. Putters with softer inserts reduce ball speed because of reduced energy transfer from the club head to the ball. To illustrate where you strike the ball on the clubface, spray the face of the putter with Doctor Scholl’s foot spray. It will show you where the ball is making contact with the face, and has minimal effect on ball speed and friction.
Certainly there are other parameters to consider, but this article should provide golfers with a general concept that they may not have considered in the past. Without knowing what the ball is doing, it is very difficult to teach someone proper putting mechanics. Players who have a better understanding of how the ball is rolling have a better chance of improving their game on the greens. Therefore, go get fit for a putter and KNOW YOUR ROLL.

AVL: We’re talking about practice! My best tips for taking your game to the course
With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter. More sunlight also means more time to get out on the course and work on your game.
Whether it’s the practice green or the driving range, there’s always something to improve—whether you’re enjoying the fresh air or preparing for a weekend game or tournament. You can work on drills or freestyle around the green, and friendly competition is a great way to sharpen your skills.
While there are endless ways to get better at golf, I’m going to focus on practicing around the green. Let’s take a look at a few things to keep in mind as we head into the summer months.
Drills
From the driving range to the practice green, it’s important to incorporate drills into your routine. Years ago, I spent a weekend working on my short game with James Sieckmann. He recommended doing drill work for 5–10 minutes, then returning to your main practice.
This way, you create a balance between structured drills and real-world scenarios, so you’re not confined to “perfect” situations. For example, hitting the same three-foot putt over and over is good for repetition, but after a while, it becomes less interactive for your brain.
My approach is to use a putting trainer with a narrow gate for the ball to pass through, or simply place tees just outside the width of the ball. I’ll hit a series of four putts through the gate for three sets. Then, from a similar distance, I’ll hit four putts without the training aid and repeat that sequence three times.
Next, I’ll hit a number of 15–25 foot putts in a random fashion, then circle back to repeat the short putt drills with and without the training aid.
This breaks up the rhythm of hitting short putts with the training aid. When you hit the same short putts over and over, it’s easy to get into a groove—which is great for the drill, but not reflective of actual course play. While finding a rhythm is fundamental for drills, I like to introduce variation with longer putts to keep things realistic.
Game Mode
Once you’ve established a foundation with drills, it’s time to simulate on-course scenarios. This is where a few practice games come in handy.
One that I’ve been enjoying lately involves putting 10- to 15-footers with two balls. If I make the putt, great! If I miss, I pull the missed ball back a putter length. Suddenly, that little tap-in becomes a nerve-wracking three-footer—at least at first. As you get better at this game, those three- and five-footers become much more comfortable and routine.
It may sound cliché, but each shot is just what it is—it’s how we react that makes the difference. I like this game because it blends the pressure of on-course putting with the consequence of leaving yourself a much longer putt than usual.
Another game I like is one I recently learned from Brad Faxon. Place three tees in a line at four different locations around the hole: one at 3 feet, one at 6 feet, and one at 8 feet. The 3- and 6-foot putts count as par, and the 8-footer is for birdie.
This game keeps you focused on scoring and helps you get into a competitive mindset. You can even think about this putting game while you’re on the course. I just started playing it, and last week I couldn’t get better than two under par.
Competition
Competition during practice is when drills and games come to life, and you start to see results. For me, nothing beats a putting contest with a friend or two. In the right setting, these contests can become talking points for the whole season.
Match play, a game of 21, or simply seeing who can make the most one-putts (with a small prize on the line) are all great ways to simulate real on-course pressure. Recently, I played in a putting contest where one competitor made back-to-back 30- and 50-foot putts. As they say, expect your opponent to make every putt—and he nearly did. That’s impressive, and it’s something you see on the course, too: you have to stay committed to your game plan, no matter what.
When it comes to practice, it’s important to blend feedback from recent rounds with the fundamentals you want to reinforce. Drills, games, and competition—from the driving range to the putting green—form the backbone of skills you’ll rely on during actual rounds.
Finding the right balance is something we’re all working on, one practice session at a time.

Seoul Sensibilities: Is Korean golf fashion starting to shape the world?
For Korean golfers, we always look forward to the last of the kkot-saem-chu-I for the true start of a new golf season. The term refers to a cold snap, but literally translates as “winter being jealous of the flowers beginning to bloom, thus lashing out one final time before surrendering to spring”.
A rather poetic mouthful packed into a short expression.
Koreans can be like that. Understated, yet oddly expressive at the same time. And nowhere is this more true on the golf course and in our golf bags. In fact, I suspect many Korean golfers look forward to new apparel and accessory drops more than they do actual equipment launches each year.

At this point, Korean golf fashion may exist on its own timeline. (courtesy of @seonbi_golfer)
There is ample evidence to support that suspicion. Korea is the world’s third-largest golf market behind the United States and Japan, yet its appetite for golf apparel exceeds that of both countries combined. Recent estimates suggest that Korea accounts for nearly 40 percent of the global golf apparel market, placing it among the world’s most influential golf fashion markets and punching well above its size.
Simply, we care deeply about how new golf clubs look and feel, but enjoy looking good while swinging them even more.
Golfers in the West may laugh and say that golf is played on a course, not a fashion runway. Perhaps. But what’s the harm in trying to look and feel good, if the added self-confidence can help actual performance? It certainly seems to have worked for Jason Day, who may have unlocked a new stats category: dormant strokes gained. Coincidence?

During the COVID-era, estimates placed the market near $9 billion, an astonishing figure for a single country.
As a proud member of Gen X, I’ve witnessed the highs and lows of golf fashion firsthand. The pleated trousers and wing-tipped shoes of Jack Nicklaus, the stylish plus-fours and knickers of Payne Stewart, the baggy black trousers and fitted mock-necks of Tiger Woods, and the thigh-hugging athletic tailoring of Rory McIlroy. Golf fashion, like the golf swing itself, has rarely stood still.
But nowhere have those trends shifted, evolved, and been scrutinized quite as relentlessly as in Korea. Here, golf fashion moves faster than fairway gossip, and consumers dissect brands with a level of discernment that can be both impressive and mildly terrifying. New brands are studied, judged, embraced, or dismissed with startling efficiency.
The result is a consumer base with one of the sharpest eyes for quality and authenticity anywhere in the world. It is difficult to quantify, but easy to recognize. Clean lines without trying too hard. Luxury mixed with utility. Trend awareness balanced by restraint and purpose.
It’s golf fashion shaped by one of the world’s most style-literate cities, something I like to call Seoul Sensibilities, referring to the taste level forged by a uniquely competitive environment.
And increasingly, global brands have noticed.

Many golf brands in Korea have their own flagship shops dedicated to apparel only
Titleist understood this years ago, when its apparel business in Korea took on a life of its own under new ownership and local direction. What had once been a straightforward extension of an iconic equipment giant became something sharper and more premium. By going all in on the serious Tour-player look (I couldn’t even fit into their XL sizes), Titleist struck the right chord with Korean consumers and helped its fledgling apparel business break into the mainstream. Titleist became a household name even for non-golfers who wore its caps, shirts, and windbreakers in daily life. In many ways, it proved that even heritage golf brands could carry real fashion credibility when viewed through a Korean lens.
Several years later, PXG took a page out of Titleist’s playbook and followed suit. Korean consumers helped transform the brand from one known largely for irons and loud commercials into something broader and more stylish. PXG apparel’s growth in Korea was explosive, where it found an early audience and turned the category into something more than mere logo merchandise. It is still hard to walk anywhere in Seoul without seeing its palindrome logo.
Malbon’s meteoric rise in the United States was genuine, but its ascent into a global golf lifestyle brand owes much to Korea, where it was elevated by a market already fluent in modern golf style. Korea did not simply embrace Malbon. It pressure-tested the concept, refined its appeal, and helped push it into the global spotlight.
As such, new brands may arrive from abroad, but more often than not, their sharpest evolution happens here. If a brand can earn credibility in Seoul, it’s deemed to have passed one of the toughest style audits in the game.
That is why the next meaningful chapter may not come from outside, but from a Korean brand moving in the opposite direction, carrying those Seoul Sensibilities outward as K-pop once did.

Play young Stay dope.
From Seoul, With Intent
Khalhon is a label that feels less like a trend-chasing newcomer and more like the product of a market that has already seen everything. Golfers here have long been surrounded by luxury logos, technical fabrics, and tour uniforms disguised as lifestyle wear and vice-versa. In other words, novelty alone rarely lasts here, and the Koreans seems to understand that instinctively.
Its style language leans into clean silhouettes, relaxed but tailored proportions, muted palettes, and premium materials that speak quietly but confidently. There is a modern city aesthetic running through it all, with strong layering pieces, thoughtful textures, and subtle branding that suggests sophistication rather than demanding attention.

“Built for the course. Designed beyond it.”
Most importantly, the garments seem designed to blur the line between golfwear and everyday style. Shirts, trousers, knitwear, and outer layers move comfortably between a game of screen golf, a lunch reservation, an airport gate, or an afternoon coffee in Gangnam with friends.
It raises the question of whether this is golfwear that happens to look good off the course, or everyday clothing that performs beautifully on the fairways.
Personally, I have long appreciated Nike Golf for its clean, athletic modernization of golf attire. It also has the useful side effect of making me look like a more serious golfer than I probably am. But off the course, there are times when being instantly identified as the golf guy in a crowd of non-golfers can feel a touch self-conscious.

“Built for the course. Designed beyond it.”
That is part of what drew me to Khalhon, which seemed to blend golf and everyday wear naturally. While some of the outfits may be slightly beyond my personal confidence level, the brand also offers tasteful options for older guys like me who still want to express a little personality without regretting the decision later.
These are not simply flashy outfits worn on the course and then banished to the closet until the next tee time. They work surprisingly well off the course too, and I suspect many of the pieces will still look right a couple of years from now, which would certainly be kinder to my wallet than most golf fashion trends tend to be.
And perhaps that broader lifestyle positioning also helps explain why someone like Sean Wotherspoon would find Khalhon creatively interesting in the first place.

“Built for the course. Designed beyond it.”
“Korea is not only one of the most fashion-forward golf markets in the world, but one of the most fashion-forward markets globally. Korea is ahead, and I love to watch and try to catch up.” – Sean Wotherspoon, Creative Director at Khalhon
Seoul and Beyond
If Khalhon’s rise says something about where Korean golf fashion is today, its relationship with Sean Wotherspoon says even more about where it is heading.
For readers less familiar with Sean Wotherspoon, his arrival at Khalhon is not some routine celebrity endorsement or influencer collaboration. In design and streetwear circles, Wotherspoon is regarded as one of the more influential creative voices of his generation, particularly when it comes to blending nostalgia, storytelling, and contemporary culture into products that people can connect with.
He first gained widespread attention through his now-famous Nike sneaker collaborations, where his vintage-inspired designs and instinct for color helped turn him into one of the defining artists of the late-2010s sneaker era. His work gradually expanded beyond footwear into apparel, automotive collaborations, collectibles, and broader lifestyle design.
Modern golf style now extends well beyond the fairways, where performance and functionality are largely expected by default. And while plenty of brands already make technically competent golfwear, Khalhon seems more focused on designing clothes people would genuinely want to wear even after the round ends.
And when guys at Wotherspoon’s level show genuine interest in working with a Korean golf brand as its new Creative Director, fashion circles tend to sit up and pay attention. There’s already a huge buzz among the fashion-conscious here about upcoming collabs with iconic sports stars and brands.

“My creative direction for Khalhon is disruptive, colorful, nostalgic, and modern. My goal is to blend these avenues seamlessly within each collection.” – Sean Wotherspoon
In chatting with Sean, what stood out most to me was how genuinely energized he sounded about the project itself. Despite having already worked across and countless other creative spaces, he described golf as a completely fresh category for him, saying that Khalhon “will be an amazing vehicle for my design work.”
At the same time, his enthusiasm seemed tied just as much to Korea itself. He spoke openly about admiring Korea’s fashion culture while repeatedly insisting he is still a terrible golfer.
There was something oddly refreshing about that humility. Rather than sounding like a celebrity parachuting into golf simply because the category suddenly became fashionable, Sean sounded genuinely curious about what Korea might do with the category next.
And perhaps that is what makes Khalhon feel interesting right now. The brand feels less like a trend-chaser and more like the natural result of a market now confident enough to export its own point of view.
For years, global brands came to Korea to sharpen their image against one of the most discerning audiences anywhere. Now, a Korean label appears ready to send those Seoul Sensibilities outward instead.
Which brings us back to kkot-saem-chu-i.
That final cold snap before spring always arrives with a reminder that seasons are changing, whether we notice it immediately or not. Golf fashion feels a little like that right now as well, as the old boundaries between sport, streetwear, luxury, and everyday style continue to soften.
And somewhere in Seoul, a Korean golf label already seems prepared for whatever season comes next. I just hope they have everything in my size.

There is some good info on this article. I also agree that people can tend to overlook putter roll. I’d be curious for a little more info that goes into greater depth about its role in the fitting process with respect to different models’ grooves, inserts, centers of gravity, etc. and how it would directly affect one’s putter choice. Cheers!
