The type of runner that will enjoy this shoe are those looking for a smooth transition and soft, yet responsive ride. They can also handle a high volume of miles with ease.
For price conscious consumers, there are alternatives to the Ultraboost 5X that won’t break the bank.
The latest Ultraboost model has been released by Adidas and officially goes by the name Ultraboost 5X. When researching past Ultraboost models, I was instantly confused by the almost random naming conventions. It was easier to search by the year than figure out the previous models.
Regardless of name, there have been some constants with the Ultraboost over the years. They are a premium priced, daily trainer that are known to have a stylish appeal. Many will argue that they’re more well known for being a casual lifestyle shoe rather than a devoted runner.
New for the 5X is a lighter version of Light BOOST, said to have the most energy return yet. PRIMEKNIT offers a light, airy upper that provides a sock-like feel. The outsole consists of CONTINENTAL rubber and added support in what Adidas calls the TORSION system. Needless to say, there’s no lack of features in the Ultraboost 5X.
Weighing in at 9.7 oz in size 9, this model drops 17 grams from last year’s Ultraboost Light. You’ll end up paying $180 which is $10 less than the Ultraboost Light as well.
I was quite impressed when I received these shoes. Out of the box, they felt lighter than expected. There’s a lot of midsole but they don’t have the feel of a max cushion shoe. The Light BOOST foam is quite flexible, making it easy to flex and contort the shoe in various ways.
On my feet, the shoes felt more like slippers than something you’d run in. The upper was very stretchy and hugged the different contours of my feet. The laces almost seemed optional at first with how snug the PRIMEKNIT felt.
During my first run, I was thankful they indeed had laces. I was hesitant to tighten these shoes the way I tie most all other running shoes. Within the first half mile, I had to stop and tie the shoe tighter.
I found that the elastic upper produced some extra movement that made the shoes feel unstable. Once I re-tied the laces the issue immediately went away.
After the run was over I felt like they performed better than I expected.
Primeknit is the elastic, textile upper that molds to your foot to give you a custom fit and feel. It is seamless and soft so there’s no need to worry about rubbing, hot spots or blisters.
Lacing is simple and smooth so it doesn’t take much effort to get a solid lockdown every time. The laces work through plastic sections that are stitched into the upper. Since the 5X doesn’t have a traditional tongue the laces cinch down either side and the Primeknit causes it to contract where the tongue would be located.
Primeknit is on the thinner side when it comes to upper materials. This makes it a great option for those steamy summer days when you need all the breathability you can get. I was particularly impressed with how the box has held up. I initially had concerns about wear and tear in the area where my big toe contacts the upper, but the elasticity of Primeknit allows it to stretch and avoid abrasion.
This is a high quality upper that is comfortable and durable while still looking good.
There’s way more than just good looks to the Ultraboost 5X.
The heel design starts with a beveled angle which reduces impact and helps guide your foot into each stride. Also contributing to a consistent gait is the Torsion System. For this newest model, Adidas sandwiches an “X” in the midfoot between midsole and outsole. A molded external heel support rounds out the back of the shoe and keeps your foot secure and locked in.
Not only is this newest version of Light Boost lighter than before, but there’s also more of it. With much of the industry moving towards more stack, the Ultraboost 5X now joins in on the fun. 38mm in the heel and 28mm in the forefoot makes the shoe feel more like a max cushion shoe while still maintaining the 10mm heel to toe drop. Because of the foam compression, the drop height is not as noticeable as other trainers. It feels more like a 8mm drop which I really liked.
I can’t say enough good things about the ride and responsiveness of the 5X.
For neutral runners, they are smooth, enjoyable and approachable. Fun for a leisurely 5k but can also endure a half marathon.
Light Boost does more to keep your legs feeling fresher for longer. What else could you ask for in a daily trainer?
Up to now, I’ve mostly considered the Ultraboost line as a leisure or lifestyle shoe. My opinion has definitely changed after reviewing the 5X. They are legitimate training shoes which I really enjoyed.
Those looking for a serious daily trainer won’t have to look far to find a more budget friendly option.
But if you like a bit of style and can afford to spend some extra coin, the Ultraboost 5X won’t disappoint!

Help needed with sizing! Love my UB22s in 8.5 but keep hearing mixed things about the 5X fit. Anyone able to compare? I mostly do easy 5K runs and lots of walking during my lunch breaks – debating if I should save some cash and go with Supernovas instead. Worth the extra $$$ for casual use?

Upgraded to the UB 5X from the 22 and the improvements are noticeable. The reduced weight makes a big difference on longer runs – just completed my first marathon in these. The Continental rubber outsole provides excellent grip in all conditions. While not as responsive as carbon-plated racers, they’re perfect for daily training. The Primeknit+ upper is more breathable than previous versions. Did a 16-week training block in these with zero issues. They’re expensive but the durability justifies the cost. Still the king of comfort in my rotation.

After 200 miles in the Ultraboost 5X, I’m thoroughly impressed. The Boost cushioning maintains its bounce even on long runs – did an 18-miler last weekend and feet felt fresh. Upper comfort is unmatched, zero hotspots or blisters. Definitely more responsive than the 4X, though still not a speed day shoe. Great for recovery runs and long runs where comfort is key. Only downside is the premium price, but durability seems excellent so far. Continental rubber outsole grips well in all conditions.

I’ve put about 200 miles on my Ultraboost 5X across various types of runs. The premium feel is immediately noticeable – from the knit upper to the plush boost cushioning. I’ve used these primarily for easy runs between 5-10 miles and recovery days. Compared to the previous Ultraboost model, the reduced weight is noticeable and welcome. The Continental rubber outsole shows minimal wear even after extensive use. While not as responsive as my Adios Pro 3 for speed work, these excel at comfortable daily miles. One minor issue is that they run warm in hot weather. I’ve found them particularly good for early morning runs around 8:30-9:00 min/mile pace.

Hey everyone! I’m torn between the UB 5X and Nike Invincible 3 for my recovery days. My legs are pretty beat up after marathon training and I need something cushy. Anyone run in both? My current UBs are falling apart after just 6 months, so hoping these last longer considering the price tag!

The Ultraboost 5X marks a significant improvement over my old 22s. After 120 miles of testing, including several half marathon training runs, I’m sold on the updates. The reduced weight is immediately noticeable, while maintaining that plush Boost feel. Perfect for easy runs between 6-13 miles. The Continental rubber outsole provides excellent grip in wet conditions. While still pricey, the premium materials and construction justify the cost for daily training. The upper breathability is much improved, though I wish they offered wider width options. Overall a worthy evolution of the Ultraboost line.

I’ve put about 150 miles on my Ultraboost 5X and they continue to impress. The Boost cushioning provides excellent impact protection while still maintaining decent responsiveness. Compared to my previous UB21, these feel noticeably lighter without sacrificing comfort. The Continental rubber outsole grips well in both dry and wet conditions. I’ve used them for everything from easy recovery runs to 15-mile long runs. While pricey at $180, the premium materials and durability make them worth it for me. The upper is more breathable than previous versions while still providing good lockdown. They’re not quite as springy as the Nike Invincible but more versatile overall.

Tried these on at my local running store yesterday. The Ultraboost 5X definitely feels lighter than my old UB22s. Upper fit is much more accommodating in the toe box. Still has that classic Boost bounce but feels more controlled. Price is steep though – $20 more than comparable premium trainers like the Ghost 15 or Ride 16. Might wait for a sale.

I’ve put these through their paces over the last month with about 100 miles of mixed running. The weight reduction is immediately noticeable compared to previous Ultraboosts – they no longer feel clunky during uptempo work. The Boost midsole maintains its bounce even on 15+ mile long runs. Upper comfort is outstanding – zero hotspots or blisters. They handle recovery runs exceptionally well while still having enough pop for tempo days. Compared to the Nike Invincible 3, these offer better stability and durability though slightly less cushioning. The Continental rubber outsole shows minimal wear. While expensive, the versatility and premium feel justify the price for those wanting a do-it-all shoe that works in multiple scenarios.

After logging 150 miles in the Ultraboost 5X, I can confidently say this is one of Adidas’ best releases yet. The weight reduction is immediately noticeable compared to previous UB models – my old 4X felt significantly heavier. The Boost midsole hits the sweet spot between cushioning and responsiveness, especially on my long Sunday runs. I’ve used these for everything from easy 5 milers to a recent half marathon. While pricey at $180, the premium materials and construction quality justify the cost. The Continental rubber outsole shows minimal wear. One minor nitpick is the midfoot cage could be more flexible. Compared to Nike’s Invincible 3, these feel more stable and versatile.

Need something I can wear for my morning runs and then keep on for running errands. Had the UB22s but they wore down pretty quick – anyone know if these last longer? Also debating if I should just save some cash and go with the Supernovas instead.

Overall, I think the Adidas Ultraboost 5.0 has strong points, but for me, it didn’t quite hit the mark. The cushioning feels great at first, and I love the stylish look, but after longer runs, I noticed the shoe felt a bit heavy and less responsive. The grip is decent, even on wet roads, but the heel started feeling loose around the 50-mile mark, so durability in terms of the fit seems questionable. It’s a solid shoe for daily short runs or casual wear, but I wouldn’t rely on it for too many intense miles.
