Key Details
- Ben Serleth wore and photographed the 2025 laceless “Off White” Climacool over several weeks.
- He moved from his usual size 10 to 10.5; the toe area felt snug initially and loosened with wear.
- The open lattice felt comfortable and airy for casual outings, but sand, mud and wet grass were drawbacks.
- These observations cover casual use of the laceless model, not a running test or a review of the Laced version.
In Summer 2025, adidas held a wider release of the Climacool “Off White,” a laceless, 3D-printed shoe. This review records Ben Serleth’s experience wearing that slip-on model for a few weeks, with original photos and observations on fit, comfort and everyday use.
The adidas ClimaCool line has been kicking around since 2002, when the Three Stripes released the shoe’s original design. The model was then geared towards performance, offering runners a shoe that emphasized breathability by adding ventilation cutouts into the midsole, and using airy mesh panels for the upper. The Clima technology was largely a success, providing relief from sweaty dogs during hot Summer runs.
The Climacool name has appeared across adidas footwear focused on ventilation. This review concerns the fully printed design, whose open lattice replaces a conventional layered upper.
The printed Climacool extends adidas’ experiments with lattice structures beyond the midsole. In its September 2024 announcement, adidas described a fully 3D-printed shoe with an open structure designed for airflow around the foot.
The printed Climacool first launched in limited quantities in September 2024, before wider releases in 2025. The testing below concerns the 2025 laceless “Off White” pair, style JQ8739. The separately listed Laced model was not the shoe used for these fit and comfort observations.
UNBOXING
Unboxing the new ClimaCool model is an experience on its own. Packed inside a standard blacked-out shoe box, the shoes come packaged in a sealed silver chrome bag emblazoned with the Three Stripes. There is no need for extra laces or paper wrappers to protect the shoes, they are ready to go right out of the box.
SIZING & FIT
The pairs available for this 2025 test came in half sizes, so I had to go up to 10.5 from my usual 10, and noticed immediately they are still a little snug in the toes. While the material is flexible, they require a little bit of stretching to slip on, especially over socks though wearing socks is entirely unnecessary and frankly, not recommended. The front narrows quickly, but with regular wear the rubbery material has expanded enough to fit fine. Having worn 4D shoes before, the new model is still a bit of a shock to the senses. There are no insoles or extra materials separating feet from shoe, and you can feel the individual printed strands, but the sensation is actually similar to adidas’ massage sandals I wore as a kid.
COMFORT
Wearing the new ClimaCool shoes truly feels like stepping into the future. Once I got past the sizing and broke them in a bit, they immediately became a go-to sneaker sitting next to my door. The midsole features a denser latticework that provides a strong and stable platform, but also gives plenty of impact resistance and cushioning for moving around. The upper is thinner than expected, and the construction is focused on sweeping lines that move with the natural contours of a foot allowing them to expand and retract with you. Like any good Clima shoe, the ventilation is on point, allowing airflow around your feet that you can feel with each step. The material used has some friction to it, but does not irritate your feet like other bare foot sneakers might. Trips to the grocery store, brunch outings, and after work bar stops all felt like traversing the world in my favorite pair of house slippers. One fun bonus of the shoe’s shock absorption I noticed is that they are nearly silent on all hard surfaces.
With that being said, they are not a “go anywhere” shoe. Cleaning out sand after a trip to the beach was a bit of a chore, and passing through an unseen wet patch of grass left me with slightly damp feet and more cleaning to remove excess mud.
Overall, the next-generation adidas ClimaCool is a win for both the Clima product line and the Three Stripes’ innovative printing technology. The shoes are squishy and light, but still sturdy enough to bop around in for everyday wear, though I do not recommend them for anything more heavy duty than casual strolls. They will certainly be an essential part of my rotation for the foreseeable future, as I continue to test their long-term durability.
