Justin Thomas’ bag setup proved every inch as ruthless as its owner this week, powering the 31‑year‑old to his 16th PGA Tour title after a playoff birdie at Harbour Town.
Brandishing a bag stuffed with Titleist’s finest—and laced with a new FootJoy HyperFlex shoe switch—Thomas tied the course record with a Thursday 61 and iced the trophy with a 21‑footer on the first extra hole.
Record‑tying start, playoff finish

Thomas’ field‑best 23 birdies included 11 on that opening 10‑under blitz, but it was his bogey‑free Sunday 68 that set up overtime drama on Hilton Head’s iconic lighthouse 18th.
One confident stroke of his Scotty Cameron Phantom 5 later, the playoff was over, and the stat sheet read:
- +3.847 strokes‑gained approach (5th)
- +5.512 strokes‑gained putting (3rd)
Not bad for a man who’d spent the off‑season obsessing over ground‑force data.
The GT2 driver and 621.JT blades formed the spine of Justin Thomas’ WITB setup all week, but the Pro V1x was its heartbeat.
Forty‑nine of 72 competitors gamed a Pro V or Pro V1x—more than six‑times the nearest rival—and nine of the final top‑12 rode that script to the pay‑window.
Why JT swears by Pro V1x
“The Pro V1x, it fits my game for a lot of reasons, but I mean my first test is always around the greens chipping. I like the sound and I like the feel of it chipping.”
“Feel is everything. If I don’t like the feel of a golf ball, I will not use it hands down. The first thing I do is I’ll hit chips and putts with it and if I don’t like the feel and the sound when I’m chipping with it, it won’t even get to the range to my irons. It’s the first thing I do. So feel is everything with me.”
“I feel like if I strike the ball how I want to or how I intend to, then the ball reacts that way. I feel like I can control the trajectory.

I feel like I can hit it high, hit it low, and the spins kind of match up with that. The ball doesn’t do something that I don’t expect it to.
If I do everything I want – I want it to apex maybe a certain height, whatever it may be – I feel like the golf ball is exactly able for me to do that.”
“Every single week, every place we play, it’s different grass, it’s different conditions, different temperature.
So I mean all of that factors in. When I’m playing East Lake, it’s hot. The ball goes a little further.
I’m playing Zoysia grass and the ball generally goes a little further off Zoysia grass. If I compress it a little bit more, I can maybe get 3, 4, 5 yards more out of it.
So a 9-iron that I normally hit a 158, 160 yards stock, I can get 170 yards almost out of it if I want to.
Versus, I go to the Scottish Open where maybe it’s 48 degrees and the ball’s sitting pretty tight, I may only be able to get 153 yards out of a 9-iron just because it’s cold, I’m not moving as well.
So it’s really, really taking in the environment and the climate and the conditions and everything and going from there.
And the reason why I know I can hit those shots is because of the consistency of the golf ball and the consistency of what I’m creating and making the golf ball do is exactly what it does.”
FootJoy HyperFlex: the quiet MVP
Long a devotee of classic kicks, Thomas swapped to FootJoy’s new HyperFlex after a Titleist Performance Institute session showed higher club‑head speeds when he increased vertical force.
“I’ve worn a classic shoe for pretty much my entire career – Classics, Icon, Premiere, etc. – but I had to make a switch when I tried this HyperFlex,” said Thomas.
“This shoe is perfect – super comfortable and flexible in the right areas, but also gives me all the support I need to make a strong, confident move on the ball.
“We spend our whole career on our feet and it is something in the past that I didn’t pay enough attention to but glad that I did this past off-season as it could be very beneficial in the long run.”
FootJoy calls HyperFlex one of its fastest‑adopted models ever, thanks to thermoplastic sidewalls that brace against sway yet flex where it counts—exactly JT’s brief.
What’s next?
With confidence in every spike and every spin rate, Thomas heads into the summer stretch looking less like a contender and more like a weather pattern—hard to predict, impossible to ignore.
If Harbour Town has taught us anything, it’s that Justin Thomas’ WITB setup is perfect for any forecast.
