In collaboration with World Number One Brooks Koepka, Nike Golf has launched the Nike Air Zoom Infinity Tour golf shoe.
The Nike Air Zoom Infinity shoe bids to provide maximum speed and comfort to golfers and is designed to produce maximum energy return from the ground up by re-harvesting and redistributing some of the energy lost during a player’s swing.
The collaboration on the project began in 2017 when Koepka challenged Nike designers to create a running shoe he could play golf in. The result of which is the Nike Air Zoom Infinity Tour shoe which looks to blend comfort and style while also generating maximum power from the ground upwards.
Speaking on the creation of the new Nike Air Zoom Infinity shoe, Matt Plumb, Nike Golf Product Line Manager stated
“Brooks was instrumental in the Air Zoom Infinity Tour iterative process, helping us get to the point where we can now help golfers look at their footwear as part of their equipment on the course.”
According to Nike, designers analysed data from pressure maps to see where traction elements needed to be positioned on the shoe for an ultimate return on movement. They developed a holistic system that transfers more power up the kinetic chain. The brand then obsessed the areas of fit (to reduce in-shoe movement), ride (for maximum energy retention) and traction (for zero slip in any direction).
The Nike Air Zoom Infinity shoe contains Nike Zoom Stroble technology and moderator plate, first tested on court by Kevin Durant in Nike Basketball’s KD12 – designed to provide structure, comfort and enable energy return needed on the golf course.
Another feature of the new addition from Nike is the company’s weather-resistant Flyknit.
The brand also borrowed design elements, and Nike REACT foam from Nike Running’s Nike React Infinity Run Flyknit for added cushioning and energy return on the golf course.
Nike’s Air Zoom Infinity Tour golf shoe releases April 1 on nike.com.
GolfWRX Vault: Avoid these 5 club building disasters
It’s never too late to go back to basics, especially when it comes to club building.
Even with modern new club release cycles the do’s and don’ts of building clubs haven’t changed much in the last few decades except for clubs with adapter sleeves and greater amounts of multi-materials incorporated into the design.
With that in mind its time to revisit an article from the GolfWRX Vault from June 2016.
I’ve been fitting and building golf clubs for more than 15 years, and in that time I’ve seen a lot of really poor workmanship—stuff that would make most GolfWRXers cringe. But like anyone who ever did anything new, I didn’t start being naturally good at putting together clubs. It took a lot of time, ruined components, and trial and error to get where I am today.
I believe my attention to detail now stems from the fact that my dad was a machinist by trade, and anytime we ever worked on something together his attitude was to take your time and do it right the first time. My dad’s approach always had an impact on me, because I feel that if you do something right — even when it takes a bit longer — the job is not only more satisfying but also makes things work better and last longer.
The goal with this article is to help WRXers avoid the most common mistakes and assumptions in club building that lead to broken or ruined clubs, as well as real danger.
Over-prepping a graphite shaft
This happens far more than it should, and can ruin an expensive new shaft purchase. To prepare a shaft properly for installation, you only need to remove enough of the paint to make sure that the epoxy adheres to the graphite. This is also true for the inside of the hosel.
Be careful to remove residual epoxy, dirt or rust (common with forged carbon steel club heads that have been sitting around for a while), or some type or solvent like the one used to put on grips, as it can cause of bond to break down very quickly. A proper reaming tool, a wire brush and some compressed air (either a small can or a large air compressor) can make cleaning simple, and prevent a golf club from falling apart.
UPDATE: Over prepping specifically applies to shafts that are designed to go into parallel heads and is especially important for 335 shafts with less material at the tip going into drivers and fairway woods. For information on how to properly taper a shaft to go into a tapered head, check out the video below:
Overheating a Shaft When Pulling it
Overheating a shaft when pulling it is another common mistake that can result in ruining a golf shaft. It also highly increases the chance of breakage. There are quite a few methods I’ve learned over the years to remove a shaft from a club head, from heat guns to large propane torches, but personally I find that using a small butane torch with a regulator for graphite offers the best results. It allows a club builder to easily control and focus the heat only where it’s needed. Bigger torches are fine for iron heads, as long as you don’t damage any plastic badges in the cavity or materials in slots around the head.
One of the best advances in club technology has been the invention and mass adoption of adjustable hosels. They not only help golfers adjust the loft, lie and face angle of club heads, but have also greatly decreased the need to pull shafts. So as long as a golfer is staying with the same metal wood manufacturer, they can usually test several different clubs heads with the same shaft, or vice versa — several different shafts with the same clubhead.
That being said, one of the most important tools that any hobbyist club builder should have or have access to is a high-quality shaft puller. It’s a necessary tool for anyone who wants to do repairs and helps prevent damage to a shaft while pulling it. The more linear pressure that can be applied to the clubhead, and the less heat used to break down the epoxy, the better. It makes sure both the shaft and the head are reusable in the future. For steel shafts, you can use a bit more heat, and twisting isn’t a problem. Again, with increased heat, be careful not to damage any of the badging, or permanently discolor an iron head.
Botching a Grip Installation
This one seems simple, but when really getting down to professional level detail, it is quite important. We ALL have a preference and different opinion of what feels good in a golf grip, as well as different sensitivities. For example, we all have the ability to figure out what apple is bigger, even if blindfolded because over time we all develop brain function to understand shapes and sizes. This also applies to grips. If you use the same grips on your 13 clubs, you could potentially have 4-5 different final sizes depending on how many different types of shafts you use, because many shafts have different butt diameters.
Some shafts have larger butt diameters, while others taper faster than others. That’s why it’s very important to own a quality set of vernier calipers, and know how to properly use them. It’s also the same for putters, since many putter shafts are smaller in diameter. I have lost count of how many times I’ve had people bring me, putters, where the bottom half of the grip is twisting and turning because the installer never paid attention to the interior diameter of the grip, the exterior diameter of the shaft, and how it changed from top to bottom.
Using epoxy that’s doomed to fail
I’m a bit of a physics nerd and garage engineer, so this is one of those topics that goes beyond just the physical aspects of club building and into the realm of chemistry.
Here comes my nerd-out moment: In the simplest of explanations for a 0.335-inch driver hosel with an insertion depth of 1.25 inches, the amount of calculated surface area the epoxy can bond between the shaft and the head using the internal dimensions of the head is 1.49 square inches. That’s not a whole lot of area when you consider the centrifugal force being applied to a driver head traveling at 100 mph, and then the forces of torque that also come into play when a shot is struck.
In a PERFECT world, almost zero torque is applied to a shaft when a shot is hit on the center of gravity (CG) of the club head, perfectly aligned with the center mass of the ball, while traveling in the intended direction. This is vectors 101 of physics. Unfortunately, almost every single shot is NOT hit like that, and this is where the epoxy bond is put under the most amount of stress. Lap shear strength of epoxy goes beyond me, but it proves that building a golf club is not just cut and glue after all.
Note: For those of you curious, the most popular epoxies are rated for 4500 psi.
As far are actually working with epoxy, first things first. Always check to see if the epoxy has a best-before date (yep, just like milk). Also, never store epoxy in direct sunlight. If you are using epoxy from a tube in a dispensing gun, you are using what is an almost foolproof method. Plunge out the necessary amount, mix for about a minute (mix! don’t whip), and remember, the less air that gets into the epoxy the better. If air gets in and the epoxy cures with bubbles in it, then you end up with a club that will often “creak.”
For those using two parts in larger bottles, the best way to ensure proper ratios is to pay attention to the weight ratio rather than volume. This isn’t arts and crafts; it’s chemistry, so by using the weight to calculate the ratio you will get the right amount of each part every time, and help decrease the risk of failure down the road. If you have mixed a larger batch and plan on building quite a few clubs at a time, you really have to pay attention to the consistency and viscosity as time goes on. You don’t want to glue a club head with epoxy that has started to set.
Turning an Extension into a Shank
This is one of those subjects I don’t even like to talk about. I very much dislike using extensions when building clubs, especially clubs with graphite shafts. Going back to my “do-it-right-the-first-time” mentality, extensions are a Band-Aid fix to a problem that requires surgery. They also counter-balance the club, and by their very nature create a weak point because of the small wall thickness at the butt end of a shaft. The only clubs I don’t mind extending on a regular basis are putters since they are never put under the same level of stress as a club being swung at full speed. I also never extend a club more than 1 inch, because I have been witness to horror stories of clubs that have been overextended that not only break but rip through the grip and cut people’s hands very badly.
If you are going to extend a club, it’s important to make sure the fit is very snug and doesn’t cause the extension to lean in any direction. It’s also best to have the epoxied extension cure with the club on its side to avoid an excess epoxy from running down the shaft and breaking off and causing a rattle.
