You've probably seen them. That chunky, bubbly white foam that looks like a cloud of Styrofoam pellets glued together. It’s everywhere. Since 2015, the Ultraboost has been the "it" shoe, blurring the lines between a serious marathon trainer and something you wear to get an overpriced latte. But the adidas men's ultraboost 22 represents a weirdly specific turning point in the franchise. It wasn't a total reinvention—adidas didn't throw the baby out with the bathwater—but it fixed the nagging issues that made the 21 feel just a little bit "off" for some runners.
Honestly, it’s a heavy shoe. If you’re looking for a featherlight racing flat to shave two seconds off your 5K PR, keep moving. This isn’t that. But for the rest of us? The people who just want to run four miles after work without our knees screaming? It’s basically a recliner for your feet.
The energy return mystery and that massive heel
When the adidas men's ultraboost 22 dropped, the big marketing push was all about the "Linear Energy Push" (LEP) system. Basically, it’s a stiff plastic insert integrated into the outsole. Why does that matter? Well, older Ultraboosts were almost too squishy. They felt great for walking, but when you tried to pick up the pace, they felt like running in sand. The LEP system adds a bit of "snap." It’s a bridge between the heel and the forefoot that prevents the shoe from flexing too much in the wrong places.
Then there is the Boost itself.
There's a massive 4% increase in energy return compared to the previous model. That sounds like a tiny number, right? In the world of midsole chemistry, 4% is actually kind of a big deal. It’s the difference between feeling like your legs are dead at mile five and feeling like you could probably squeeze out one more lap. The heel stack height is significant. It’s chunky. This helps rearfoot strikers—which, let’s be real, is most of us—absorb the impact of hitting the pavement.

What’s actually inside the midsole?
The foam is made of expanded Thermoplastic Polyurethane (eTPU). Adidas worked with the chemical company BASF to develop this years ago. They take tiny TPU granules and basically pop them like popcorn. Each one of those thousands of little "capsules" holds a tiny pocket of air. When you land, they compress. When you lift your foot, they bounce back. It’s remarkably temperature-resistant, too. Unlike traditional EVA foam, which gets hard as a rock in the winter and mushy in the summer, Boost stays pretty consistent.
Primeknit+ is the unsung hero of the adidas men's ultraboost 22
The upper is where things get interesting. Adidas uses Primeknit+, which is essentially a high-performance sock. But it’s not just about comfort. The 22 used data from 1.2 million foot scans to refine the fit. Interestingly, while the 22 was famous for its female-specific redesign, the adidas men's ultraboost 22 benefited from a more refined heel "S-curve."
Have you ever had that annoying rubbing on your Achilles tendon? The 22 solves this with a notched heel design. It pulls away from the tendon so there’s zero friction.
- Sustainability factor: The yarn in the upper contains at least 50% Parley Ocean Plastic.
- Locked-in feel: The midfoot cage is still there. Some people hate it because it feels restrictive, but if you have narrow feet, it’s a lifesaver for stability.
- Breathability: It’s decent, though Primeknit is notoriously warm. If you’re running in 90-degree humidity, your feet are going to sweat. There’s no way around it.
The Continental rubber grip
You can't talk about this shoe without mentioning the outsole. It’s Continental rubber. Yes, the tire company. It’s arguably the best traction in the running world. Whether the pavement is bone-dry or slick with morning dew, these things stick. I've worn these on wet wooden boardwalks—usually a death trap for runners—and didn't slip once. The "Stretchweb" pattern allows the outsole to flex with the Boost foam, so you aren't fighting the shoe as you move through your gait cycle.

Is it actually a "real" running shoe?
This is where the elitists start arguing. Some hardcore track athletes look down on the adidas men's ultraboost 22 because of its weight. It clocks in at around 11.7 ounces (333 grams) for a men's size 9. For context, a dedicated speed shoe like the Adizero Adios Pro is significantly lighter.
But here is the nuance: Most people aren't elite.
If you are a "lifestyle runner"—someone who does 10 to 20 miles a week at a moderate pace—weight doesn't matter nearly as much as injury prevention and comfort. The 22 is a tank. It’s durable. While most running shoes start to die after 300 miles, you can easily get 500 or even 600 miles out of a pair of Ultraboosts. The Boost foam simply doesn't bottom out as fast as standard foams.
The "All-Day" versatility
The reason this shoe dominates the market isn't just because of the tech; it's because you can wear them with jeans. It sounds superficial, but it’s true. You can finish a run, head to the grocery store, and not look like you’re wearing neon-colored space boots. The aesthetics are intentional. The silhouette is sleek.

Common gripes and real-world issues
- Tightness over the instep: If you have high arches, that Primeknit can feel like a blood pressure cuff for your foot. You might need to size up or skip the top eyelets.
- The "Bottoming Out" myth: Some heavier runners find that after an hour of running, the foam feels less responsive. This is a common critique of eTPU; it’s great for short bursts but can feel "dead" during long-distance endurance sessions.
- Price point: At an MSRP of $190, it's an investment. You’re paying for the R&D and the branding.
How it compares to the newer models
Since the 22, we’ve seen the Light and the 5. You might wonder if you should just skip the 22 and go for the latest version. Honestly? It depends on your budget. The newer "Light" version is—shocker—lighter, but some fans of the original feel it lost that signature "mushy" comfort that made the Ultraboost famous. The adidas men's ultraboost 22 sits in that "Goldilocks" zone. It has more structure than the early versions but more soul than the hyper-engineered newer ones.
If you find a pair of 22s on sale? Grab them. The differences between the 22 and the 23 (Light) are noticeable but not necessarily a "dealbreaker" for the average person.
Maximizing your pair: Actionable steps
To get the most out of your adidas men's ultraboost 22, you shouldn't just lace them up and forget about them. There are a few ways to ensure they last and perform.
- Don't put them in the dryer. The heat can compromise the glue and the knit. If they get muddy, use a soft brush and some mild soap, then air dry.
- Swap the insoles. If you need more arch support, the factory insoles are pretty thin. Replacing them with a semi-rigid orthotic can turn this into a much more stable shoe for overpronators.
- Rotation is key. Don't wear them every single day if you’re using them for exercise. Giving the Boost foam 24 to 48 hours to "decompress" between runs will actually extend the life of the material.
- Check the tread. Once those little rubber "nubs" on the Continental outsole wear flat, you lose the benefit of the Stretchweb tech. That’s your signal to transition them from "running shoes" to "walking-the-dog shoes."
The adidas men's ultraboost 22 isn't a perfect shoe—nothing is—but it’s a remarkably consistent one. It’s the reliable friend of the sneaker world. It shows up, does its job, and keeps your joints from feeling like they’ve been pounded with a mallet. Whether you're standing on your feet all day for work or training for your first 10K, the blend of eTPU and Primeknit remains one of the most successful combinations in footwear history.
For those looking to buy, keep an eye on the heel counter. If you notice any clicking or movement, re-lace using a "runner's loop" (heel lock) to take full advantage of that S-curve heel design. It makes a world of difference in preventing slippage. Check your local retailers or the official adidas site for remaining stock, as colorways like "Core Black" or "Cloud White" tend to disappear fast due to their crossover appeal in fashion circles.
