The Adidas Ultraboost 5X takes a bold step forward in the Ultraboost family, offering a ride that feels lighter, springier, and just all-around more enjoyable. Designed with everyday runners in mind—especially those who care about cushioned comfort and fluid transitions—this version nails it with an urban-savvy style and premium feel that make it much more than just a running shoe.
Primeknit upper:
Slip your foot into the Ultraboost 5X and you’re greeted by that familiar, snug Primeknit hug. The upper is soft, stretchy, and wraps your foot like a cozy sock—no rubbing, no stiff seams, no pressure points. Right out of the box, the comfort hits. It’s a dream especially for folks with wider feet or those who like a bit more space up front.
That extra give also means they slide on and off with minimal effort, which, honestly, makes them a joy for daily wear. Ventilation-wise, they won’t keep your feet icy in a heatwave, but for everyday temperatures, the airflow gets the job done.
Light BOOST midsole:
Here’s where things really get exciting: the Light BOOST foam. This newer compound trims weight while still packing in the bounce. Compared to earlier versions, it compresses more readily but springs back with a satisfying energy. You get that plush feel underfoot without feeling like you’re sinking.
Perfect for logging relaxed miles or cruising through longer runs—we’re talking 15 km and beyond—without your feet begging for mercy. Just don’t expect them to shine during tempo sessions or speed drills. When you pick up the pace, they lean more toward comfort cruiser than speedster.
Traction and durability
Underneath, Continental rubber takes care of grip, and it’s no joke. Whether you’re on damp sidewalks or dry pavement, the traction holds steady. It’s reliable, sticky in a good way, and wears like a champ. Even after piling on the miles, the sole barely shows signs of breakdown.
The Torsion System tucked between the heel and forefoot adds just the right amount of stiffness to keep transitions smooth. Even with the shoe’s inherent flexibility, it doesn’t feel wobbly. That balance gives you confidence, whether you’re running or just power-walking to your next meeting.
Fit and ergonomics
When it comes to fit, the Ultraboost 5X doesn’t mess around. The absence of rigid elements through the midfoot means your foot can move naturally, no restrictions. That seamless interior? Big win for comfort over the long haul. No hot spots, no rubbing—just a smooth ride.
Plus, the heel area is thoughtfully padded. It cradles the back of your foot just enough to keep things stable, without ever feeling bulky or overbuilt. Whether you’re out for a jog or dashing between errands, your foot stays locked in and happy.
Weight and running feel
Now here’s a pleasant surprise: at 275 grams for a men’s size 9 (EU 42), these kicks feel feather-light for a max-cushion trainer. That weight drop adds a welcome dose of agility. Your stride flows a little easier, your feet lift off a little quicker.
They’re not built for race day, sure, but for recovery jogs, easy daily miles, or just long city strolls, they’re absolutely spot on. Think of them as your all-day comfort companion.
Style, versatility, and build quality
Looks-wise, the Ultraboost 5X keeps that sleek, future-forward vibe alive. They look right at home in the gym, at the coffee shop, or even paired with casual office wear. Adidas clearly didn’t phone it in—every stitch, every panel feels intentional and high-end.
With a range of colorways, it’s easy to match them to your wardrobe, and the upscale finishes give them a premium edge that goes beyond pure function. They look and feel worth the price tag.
Conclusion
The Adidas Ultraboost 5X is for anyone who puts a premium on comfort and everyday versatility. From its sock-like Primeknit upper and springy Light BOOST midsole to the grippy Continental outsole, it covers all the bases for mellow training sessions, weekend walks, or just standing all day without thinking twice about your feet.
No, they’re not speed demons or hot-weather champs. But they don’t need to be. Their easygoing charm, thoughtful design, and all-around comfort make them a standout pick for anyone who wants a shoe that does it all—and looks good doing it.
