You've seen them on the feet of every runner in the city for the last decade. That chunky, bubbly white midsole. The Primeknit upper that feels more like a sock than a shoe. When the adidas Ultraboost golf shoes finally dropped, the hype was massive. People expected the clouds-under-feet feeling of a marathon shoe combined with the grip needed to rip a driver 290 yards. But here’s the thing: most golfers actually misunderstand what these shoes are for, and they end up disappointed because they’re using them the wrong way.
Golf is a game of lateral force. Running is a game of forward momentum. Putting a running engine into a golf chassis is like putting a Ferrari motor in a Jeep—it’s powerful, but if you don't know how to handle the torque, you're going to slide off the road. Or, in this case, slide right out of your follow-through.
The Boost Paradox: Is Too Much Comfort Actually Bad for Your Swing?
Let’s get real about the tech. Adidas' proprietary "Boost" foam is made of thousands of expanded thermoplastic polyurethane (eTPU) capsules. They are heat-welded together. It's basically high-grade chemistry that returns energy better than standard EVA foam. On the 14th hole when your legs feel like lead, that energy return is a godsend. You feel fresher. You aren't dragging your feet to the green.
But there's a trade-off.
The very softness that makes the adidas Ultraboost golf shoes feel like slippers can be a nightmare for high-swing-speed players. If you're swinging the club at 110 mph, you are exerting immense pressure on the outside of your lead foot. Standard running shoes would give way. Your foot would "roll." To fix this, adidas didn't just glue spikes to a running shoe. They added a reinforced microfiber leather "cage" and used a stiffer version of the Primeknit.
It’s still soft. Kinda too soft for some. If you’re a "ground force" golfer—someone like Justin Thomas who practically jumps off the ground—you might find the Ultraboost a bit "mushy." But for the walker? For the person who carries their bag and racks up 12,000 steps a round? There is literally nothing else that competes. It’s a specialized tool, not a universal fix.

The Spikeless Reality Check
Look, these are spikeless.
We need to stop pretending spikeless shoes are "just as good" as metal or hard plastic cleats in a torrential downpour. They aren't. The adidas Ultraboost golf shoes utilize a rubber outsole with a lug pattern inspired by their "Strechweb" design. It’s great on dry grass. It’s phenomenal on the fairway. It's even surprisingly decent on pine needles.
But if you’re playing at 7:00 AM on a Tuesday in Scotland and the dew is thick enough to drown a frog? You’re going to slip.
Honestly, that's okay. These shoes occupy the "lifestyle-performance" niche. They are designed for the golfer who goes from the office to the range, or the weekend warrior playing a suburban parkland course. They aren't trying to be the footwear choice for the US Open at Oakmont. Understanding that limitation is the difference between loving these shoes and feeling like you wasted $200.
Sustainability Isn't Just a Buzzword Here
One thing adidas actually gets right—and they’ve been doing this since their partnership with Parley for the Oceans started years ago—is the material science. A huge portion of the upper in the latest Ultraboost golf iterations is made from recycled polyester. They call it Primegreen or Parley Ocean Plastic depending on the specific model year.

It’s not just "greenwashing."
The performance of the recycled yarn is identical to virgin plastic. It’s breathable. It’s stretchy. It handles sweat remarkably well. Most golfers don't care about the planet when they're staring down a 4-foot par putt, but it’s a nice bonus to know your hobby isn't adding more raw plastic to the landfill. The durability has also improved. Early versions of Primeknit would snag on every rogue twig or bramble in the rough. The newer weaves are tighter. They're more "shielded."
What Most People Get Wrong About Sizing
Here is a pro tip: do not buy your standard golf shoe size in these.
Golf shoes from brands like FootJoy or even some Nike models tend to run slightly wide or "stiff" in their sizing. The adidas Ultraboost golf shoes are built on a running last. They are narrow through the midfoot and snug in the heel.
- If you have wide feet, you almost certainly need to go up a half size.
- If you like a "locked-in" feel, stay true to size but expect a break-in period for the knit.
- Wear thin socks. These shoes are designed to fit like a second skin; thick wool hiking socks will ruin the geometry of the footbed.
I’ve seen guys complain that the heel "slips" during the swing. Usually, it’s because they bought them too big, thinking they needed the extra room they’re used to in a heavy, leather saddle shoe. You don't. The knit expands. It breathes. It moves with you.

Let's talk about the white foam. The "Boost" midsole is iconic, but it’s a magnet for dirt. Once that white foam gets stained with mud or grass juice, it’s a pain to get back to that "out of the box" glow.
Professional caddies will tell you: warm water, a bit of dish soap, and a soft-bristled toothbrush. Don't put them in the washing machine. The heat can mess with the adhesives holding the Boost capsules together. If you treat them like a piece of high-end equipment rather than a pair of beat-up sneakers, they’ll easily last 50–60 rounds. But if you're someone who tosses your shoes in the trunk of a hot car and leaves them there for three days in July? The foam will eventually lose its "pop."
Why the "Golf" Version Actually Matters
You might be tempted to just wear your regular Ultraboost runners to the course. Please don't.
Beyond the traction, the adidas Ultraboost golf shoes have a lower drop. In running, a "drop" is the height difference between the heel and the toe. Standard runners have a high drop to propel you forward. If you golf in those, you'll feel like you're standing on your tiptoes. Your weight will shift too far into your toes during the swing, leading to shanks and balance issues. The golf version flattens that out. It keeps your center of gravity where it belongs—over the arches of your feet.
Moving Toward a Better Round
If you’re struggling with foot fatigue or you simply hate the "corporate" look of traditional golf shoes, the transition to a Boost-based shoe is a literal game-changer for your physical comfort. Just remember that you're trading a bit of "stiffness" for a lot of "cushion."
To get the most out of your pair, start by wearing them around the house for an hour to let the Primeknit adapt to your foot shape. When you hit the course, pay attention to your balance on uneven lies. You might find you need to slow your tempo just a fraction to stay stable in such a soft shoe. Clean the midsole after every round with a damp cloth—don't let the grime set in. Finally, pair them with a technical "no-show" sock to maintain the airflow the shoe was engineered for. Your feet will thank you by the time you reach the 18th green.
Actionable Insights for the Aspiring Ultraboost Owner
- Dry Weather Specialist: Keep these as your "fair weather" shoes. They excel in dry, firm conditions where comfort is the priority.
- The Sizing Trick: Go up a half size if you’re coming from a traditional leather brand like FootJoy.
- Midsole Care: Use a Mr. Clean Magic Eraser on the white Boost foam to keep it looking new—it works better than any specialized shoe cleaner.
- Know Your Swing: If you have an extremely aggressive, high-speed lower body move, consider the "Tour360" model instead for more lateral support. Use the Ultraboost for casual rounds and walking heavy days.
