Nuestra conclusión

Las Adizero Adios 9 son una atrevida renovación de la mano de Adidas que ha traído de vuelta el espíritu de las voladoras de la vieja escuela, pero que también toma prestados elementos de las Adios Pro 4, unas superzapatillas de primera categoría. De hecho, tienen el mismo upper, la misma espuma, y hasta la misma suela exterior. Lo que las separa de estas primas no tan lejanas es que su suela es mucho más baja, que no tienen placa de carbono y que se venden a un precio mucho más asequible. Nos quedamos encantados con la energía de su pisada, pero se quedan cortas tanto en estabilidad como en versatilidad para las largas distancias.

Who should buy

After hitting the roads and pushing it to the limits in the lab, we think that the Adios 9 is the perfect shoe for:

  • Runners who miss old-school racing flats with low stacks and zero plates.
  • Those wanting a tempo-ready shoe that feels fast and natural.
  • Lightweight midfoot strikers seeking a shoe for fast-paced efforts with massive energy return.
  • Fans of the Adizero Adios 8—because version 9 is a huge upgrade.

Who should NOT buy

We think the Adios 9 isn’t the best choice for runners needing generous cushioning. It's low-stack build feels ultra-connected to the ground but may fall short for those wanting the ultimate leg-saving experience. From our perspective, the Adizero EVO SL is a better fit for those individuals, as it adds extra stability and a thicker Lightstrike Pro midsole for a similar price.

Additionally, we do not recommend the Adios 9 to runners who expect a supershoe-like experience. We discovered it lacks the rigid, carbon-plated snap that defines that category. For a more race-ready feel in a low-stack format, we suggest the Nike Streakfly 2 or the New Balance FuelCell SuperComp Pacer v2.

Those chasing a connected ride will find a hidden gem in the Adios 9—its 25.0 mm stack delivers an agile-underfoot feel that’s perfect for runners who want control and close-to-the-ground feedback.

On the flip side, if you're used to maximalist shoes like the Hoka Clifton 10 or the ASICS Novablast 5, this low-profile setup may feel too raw. It’s clearly built for short or medium runs at fast paces, though we discovered it can cruise slow too thanks to its ultra-flexible design.

The forefoot dips under the 20 mm mark—an uncommon trait in today’s maximalist world. But that’s where the Adios 9 shines, delivering a race-flat-inspired ride that feels snappy, nimble, and seriously fun.

Of course, your muscles will do extra work with the Adios 9 compared to any supershoe like the Nike Vaporfly 4. We found it best suited for lightweight runners who want a stripped-down, speed-loaded experience. On the other hand, bigger runners may want to skip it—the thin slab of foam will definitely bottom out under heavier strides.

Drop

This “track-spikes-for-the-road” type of shoe usually sticks with a low heel-to-toe drop, yet the Adios 9 bucks that trend with a moderate one. We measured 6.2 mm—slightly below the stated 7 mm.

From our perspective, this drop makes the Adios 9 a midfoot-striker’s dream. Still, we discovered it remains very usable for everyone else, though heel strikers may feel a bit unstable on this one for reasons we’ll delve into in a minute.

Suavidad de la mediasuela

The Adios 9 has many strengths, but the main one lies in its midsole—finally we get 100% Lightstrike Pro with crazy-high energy return. Previously it used some EVA foam in the heel that made the ride less fast and exciting, but now you get the same high-performance compound used in state-of-the-art Adidas’ supershoes—just at a more wallet-friendly price.

We were also surprised by how soft the Adios 9 felt underfoot, which felt like a bold move given the minimal stack. Later, we confirmed this plush sensation in the lab with our Shore A durometer, which read 16.0 HA.

Do we think it’s a bad call? Not at all. Most runners—especially lightweight men and many women—will likely enjoy this soft and responsive feel. It just makes the shoe slightly less suitable for heavier individuals, but that’s already implied with this low-stack design.

Rocker

We wouldn’t call the Adios 9 a supershoe as it skips the carbon plate, but for fans of old-school flats, it’s a dream. It brings that stripped-down, low-stack ride with just enough help from Adidas’ energetic Lightstrike Pro midsole. There’s a moderate rocker, but at the end of the day, it's just your legs doing the work.

And we liked that heel strikers aren’t left out. The moderately rockered heel, combined with Adidas’ signature inward-angled geometry, creates a natural-feeling entry point that guides the stride without being overbearing or intrusive.

Plate

Slicing shoes in half has its perks—one being that we can uncover the unfiltered truth. In this case, there’s no plate inside the Adios 9, but a thin plastic insert like the one in the Adizero EVO SL or the Nike Streakfly that adds a touch of snap while keeping the ride ultra-flexible and natural.

Before taking any measurements, we tested the Adios 9 on our feet. It clearly felt a bit snug—something we fully expect from a performance-driven shoe anyway.

Thanks to our 1:1 gel mold of the shoe's interiors, we then measured the widest part of the Adios 9 at 94.3 mm, which falls slightly below the average.

We discovered that the snug sensation mostly comes from the tapered toebox, which measured just 70.6 mm.

One of the standout features of the Adizero Adios 9 is that it shares the outsole with its premium cousin, the Adios Pro 4—yet comes at a much lower price. As a result, it delivers top-tier grip in both dry and wet conditions thanks to the blend of LIGHTTRAXXION and Continental rubbers, confirmed by its 0.55 score in our SATRA TM144 test.

Estabilidad

Prueba de estabilidad lateral

After reviewing hundreds of shoes, we discovered that stability and fun rarely go hand in hand—and the Adios 9 proves it. This high-energy, featherweight shoe feels thrilling underfoot, but it demands solid form, especially if you're landing on its ultra-narrow heel.

Rigidez torsional

The small plastic insert in the midfoot adds only minimal stiffness, so when we tested the shoe, torsional rigidity came out quite low at just 2/5. That's why this shoe feels great at slower paces too.

The heel counter screams racing vibes at 1/5, it has zero reinforcements or structured elements. As we mentioned before, if you land on the heel, stabilization is all on you. 

On the bright side, the upper vanishes completely on foot and never gets in the way, delivering a natural-feeling ride.

Anchura de la mediasuela - antepié

The Adios 9 is a compact-sized running shoe—both in height and width. We noticed it right after unboxing it in the lab, and it was clear it wouldn’t hit the average on our measurements.

However, the forefoot reached 110.8 mm, which we believe is ideal for a speed-focused design like this. It’s certainly narrow, but it lands in that sweet spot—streamlined yet not foot-squeezing.

Flexibilidad / Rigidez

Anyone expecting a supershoe-like, stiff feel here will find exactly the opposite. We measured 5.2N in our lab—one of the lowest results we’ve ever recorded.

This level of flexibility turns the Adios 9 into a foot-strengthening, proprioception-boosting tool for runners and makes it one of the best 5K/10K racing shoes for those who don’t get along well with carbon plates, either due to their harsh feel or because of issues like Morton’s neuroma.

Peso

The Adios 8 tipped our scale in the lab at 7.40 oz or 210g—a nice result already. But the Adios 9 took things further, dropping to just 6.20 oz or 176g. That’s a stunning improvement.

So, how did Adidas pull this off? While the Adios 8 relied on a heavier dual-foam setup, version 9 uses only Lightstrike Pro, and that's how Adidas shaved grams while improving bounce.

Transpirabilidad

The Adios 9 features the same LIGHTLOCK upper as the Adios Pro 4, offering a significant upgrade over previous versions. However, as we observed with its supershoe counterpart, it faces challenges with ventilation. This is another reason we suggest limiting its use to short distances.

Our smoke test revealed that most air becomes trapped inside the shoe, leading us to assign it a 2/5 rating for breathability. While not ideal, issues may only arise on particularly hot days, especially if paired with thick socks.

On the plus side, the insole features oversized ventilation holes that boost airflow slightly—and it's always cool to discover a high-end touch in a reasonably-priced shoe.

Upon examining the upper under a microscope, we immediately understood the reason for its low score.

The LIGHTLOCK technology creates a unidirectional fabric that stretches in only one direction to enhance stability. However, this design lacks ventilation holes, making the upper resemble a Gore-Tex material.

We found the upper to be exceptionally lightweight, prioritizing weight reduction over comfort, with minimal foam padding in the tongue and heel.

Dureza de la suela

One thing Adidas often does with lower-priced shoes is downgrade the outsole compound—like using Adiwear on the Pureboost 5 instead of Continental rubber on the Ultraboost 5. Fortunately, that’s not the case with the Adios 9, which makes this another bang-for-the-buck feature we love.

Adidas Adizero Adios 9 outsole design

Here, we get almost the same outsole found on the Adios Pro 4—a combo of full-length LIGHTTRAXXION with a Continental patch in the forefoot to boost grip during toe-off.

This LIGHTTRAXXION material isn’t your average rubber. Made from translucent polyurethane, it aims to balance durability, grip, and a lightweight feel. Big promises—but with a softness of 51.0 HC, the traction definitely delivers.

And durability holds strong in both the LIGHTTRAXXION material and the Continental patch. We measured just 0.6 mm of wear in the former and 0.54 mm in the latter—impressive for such lightweight-yet-grippy compounds.

The tongue is really thin at 2.6 mm, though that measurement shows Adidas added a light touch of padding. In our view, it strikes a good balance for a tempo trainer—thicker tongues usually belong in slower, comfort-focused shoes.

The eyelet chain comes straight from the Adios Pro 4, and we found it works great. You can dial in the fit as tightly as you want without risking the tear-prone issues seen in the Adios Pro 3.
