The Adidas Ultraboost 23 keeps showing up on best running shoes lists and for good reason.However with so many new options flooding the market in 2026, does it still deserve that top spot? I’ve put this shoe through its paces, and here’s what I actually think.
First Look: Sleek Design That Means Business
The Ultraboost 23 looks premium right out of the box.Adidas refined the Primeknit upper to feel softer and more sock-like than previous versions.Moreover the Linear Energy Push system gives the outsole a more aggressive, forward-propelling feel underfoot.
The heel counter feels snug without pinching. In fact, it locks your foot in place better than earlier Ultraboost models did. Overall, the fit is one of the best in this price category.
Sizing And Fit
The shoe runs true to size for most people. That said, runners with wider feet should try before they buy the toe box is moderately narrow. Additionally, the Primeknit upper stretches slightly over time, which helps with break-in.
Performance On The Road And Treadmill
Boost Cushioning: Still The Gold Standard?
The full-length Boost midsole is what everyone buys this shoe for.It delivers a spring responsive feel that genuinely returns energy with each stride.Furthermore the cushioning stays consistent whether you’re running 2 miles or 10.
However runners who prefer a firmer more stable platform may find Boost a bit too soft.For example, those training for a marathon with high weekly mileage might want to pair this with a plated carbon shoe for race day. For everyday training runs, though, the Ultraboost 23 handles it all with ease.
Grip And Outsole Durability
The Continental rubber outsole gives solid grip on wet roads. As a result, you won’t have to slow down much when it rains. The outsole also holds up well over months of regular use I’ve seen pairs log 400+ miles without significant wear.

How It Stacks Up Against Newer Models
New running shoes drop every few months. Therefore, it’s fair to ask whether the Ultraboost 23 still keeps up. The answer is yes with some caveats.
Shoes like the New Balance 1080v13 and ASICS Gel-Nimbus 26 offer similar comfort levels.However the Ultraboost 23 wins on style and everyday versatility.You can wear it for a 5K in the morning and grab coffee in it afterward without looking out of place.
Comfort For All-Day Wear
Beyond running the Ultraboost 23 works as a daily lifestyle shoe.The Boost foam absorbs impact well on hard pavement or concrete floors.Additionally the breathable upper keeps feet cool during long stretches on your feet.
That said, dedicated gym training isn’t this shoe’s strength. The soft midsole doesn’t provide the lateral stability you need for weight training or HIIT workouts.
Final Thoughts
The Adidas Ultraboost 23 earns its reputation as one of the best running shoes available in 2026.It delivers plush cushioning, a premium fit and enough versatility to work beyond the track.Furthermore the build quality justifies the price tag for serious runners and casual wearers alike.
If you want a reliable daily trainer that feels great mile after mile, the Ultraboost 23 still belongs at the top of your shortlist. Overall, Adidas got this one right and it still shows.
