  • A few consumers didn’t like the fit profile of this shoe as they felt that it was a bit narrower than their standard fare.

Bottom line

The Adidas Adizero Adios 4 was reasonably well-received. Those who have tried this neutral running shoe were glad because it was light and responsive to their movements and overall performance.

    Adidas Adizero Adios 4: For speed with comfort

    The Adios is a lightweight, reactive shoe that lends itself well to faster runs. It is the faster of the Adizero range, where the Bostons provide a bit more cushioning for those longer training runs and races.

    Its main purpose is speed, and that is why it is a popular choice for elite runners and is often seen at races.


    First impressions

    If you love the adios, the look of the 4 seem quite foreign to you. It does not share the same features as the previous Adios. Gone are the old-fashioned stripes and old-style running shoe look (I personally prefer the old look).

    The feel of the upper textile has a bit more integrity than the previous version which gives it a feel of firmness on foot and a little less give, which may make the wearing in a period a bit longer. Not quite the buy and go for a run kind of shoe.



    Structurally, the outer sole still shares the same durability and support that you would expect in an Adizero. The inner sole boost technology provides slightly more cushion than its predecessor which will definitely make it more suitable for achieving those marathon PBs instead of just the 5km and 10km races.

    The laces have been made more durable and longer (perhaps they listened to the few complaints about the laces in the previous models). Above you can see the difference in the overlay design, lacing and upper mesh between the 4 and 3, respectively.

    First few runs

    On the first inspection, the Adios 4 design looks quite different from the 3. The textiles used on the upper feel a bit firmer and thicker and with less overlays. I was quite aware of the rigidity when I went for my first run.

    Although it was the same size I usually wear, it felt a bit more constructive in the forefoot than my 3. As a result, I got a few minor blisters on my little toe on both feet. The lace holes are also a bit different. They have been placed slightly narrower than the ones on the 3 due to the change in the overlay design.

    This may be the reason for the more constrictive feeling that I felt during the run. The laces themselves are also different. This is definitely an improvement on the 3, as they are longer and stretchier.

    The rest of the shoe is pretty much the same as the 3, and that’s the design that makes them one of the most popular speed/racer shoes. They are super lightweight, they have a grippy continental outer sole, and they have a very reactive inner sole boost foam.

    These characteristics are why I love the Adios and are my first choice for marathons and shorter distance races. One thing I do struggle with on the outer sole is the hard plastic piece under the midfoot. If you climb up a curb or land on a rock at just the wrong angle, it can be quite slippery and leave you a little off balance.

    Sizing & general feel

    These are a small snug fit brand of shoe, as they are designed to be a fast-paced racer shoe. With this being said, I felt that I had to go one and a half sizes bigger. But, with the neat styling of the shoe, they still manage not to drown your feet.

    They are super lightweight weighing around 8 ounces (US 9) and definitely give that barely-there feel. This is because there is a bit less boost foam in the midsole in comparison to the other Adidas shoes like the Ultraboost. The 10mm heel drop makes you feel quite connected to the ground, giving good feedback.


    I have found these shoes to be very durable and quite long lasting. I have worn mine for runs past the recommended mileage of 600-800km, provided you don’t take them for too long of a run once they are past the recommended mileage, as this may lead to a few foot and knee complaints.

    The upper mesh holds up quite well, and I have not had anywhere the mesh has torn or weathered. The continental rubber outer sole is very durable and resistant to wet and dry terrain with quite a reliable traction even on some tough trail routes.



    This comes in handy if you are a fan of combining road and trail to your training (like me). The Continental rubber outer sole that is seen on the Adizero range.

    The things I like

    1. The continental rubber outer sole is durable and resistant to wet and dry terrain (I even run mine on a few rough trails)
    2. They are very lightweight with that barely there feel on your feet
    3. Neat and minimalistic styling with less overlays than previous versions
    4. Breathable upper mesh (but not as breathable as previous versions)
    5. Midsole boost technology/foam that offers enough cushioning

    The things I don’t like

    1. Limited styling/colors
    2. The upper mesh is a bit too rigid compared to the Adios 3
    3. Feels slightly narrower than the Adios 3


    Overall, I am a fan of the Adizero range, and they are my preferred running shoe. They are not designed for everyone. If you are a bit heavy footed or pronate/supinate runner, then you are probably better off with a shoe that provides more cushioning and support.

    It's a good shoe. It's a fun shoe.

  • 87 / 100 | kofuzi | Level 4 expert

    I think my overall take on this shoe in terms of the materials used and the aesthetic is that this could really be a performance retro.

  • 98 / 100 | Road Trail Run | | Level 5 expert

    Smooth, efficient, snappy, powerful and!

  • 92 / 100 | Road Trail Run | | Level 5 expert

    The ride is snappy with plenty of heel cushion and a thin responsive forefoot.

  • The Adidas Adizero Adios 4 is a running shoe that’s designed for those who have neutral pronation. It utilizes a full-length boost™ midsole to cushion the landings and maintain a hearty performance throughout the running session. A thermoplastic support frame maintains the structural integrity of the midfoot.
  • The upper unit of this road companion features Open Mesh which is a highly breathable and lightweight material. It is flanked by a moisture-resistant interior lining and a memory foam collar to complete a form-fitting in-shoe experience.

The Adidas brand has advised consumers to consider a pair that’s half-a-size bigger than their regular choices as the Adizero Adios 4 is apparently smaller than the usual. Trying on a pair or check out user feedback from online sources greatly help in locking in the right size.

When it comes to width, the available options are D – Medium and B – Medium for men and women, respectively. This entry in the road running category welcomes runners who have medium foot dimensions.

The outsole unit of the Adidas Adizero Adios 4 is made up of Continental™ rubber, which is one of the most durable technologies in the market. The material is commonly used in race car tires, giving a long-lasting performance during those multi-tiered races. Now, it extends its protective and skid-resistant nature to outsoles, heightening the quality and value of the shoe.

Adidas external pads are known for their grid-like designs. This seemingly optical trait offers an elevated purpose: to increase the potential for precise traction and foot flexibility through textured nodes and shallow multi-grooves.

Boost™ is the Adidas Adizero Adios 4’s midsole unit. This full-length foam is made up of thousands of thermoplastic polyurethane (TPU) pellets that have been fused together to create a bouncy and shock-resistant piece. The job of the boost™ foam is to maintain comfort without diminishing in form or weighing down the foot.

A thermoplastic skeleton called Torsion System is placed in the midfoot section of the platform. The purpose of this visible add-on is to preserve the structural integrity of the boost™ midsole. It also supports the muscles and tendons of the underfoot, making them feel as though they’re buoyed continuously by a sturdy but unobtrusive frame.

A sock liner is placed above the main cushioning system. This extra piece adds some more cushioning for the foot-pad. It can be removed or replaced with a new one if desired.

Open Mesh is used for the upper unit of the Adidas Adizero Adios 4. This porous textile accommodates air into the foot-chamber, allowing the foot to experience an airy and dry interior throughout the running session.

The interior sleeve of this running shoe is made using Coolever Mesh Lining. This fabric technology has a softness that prevents chafing and a capacity to wick off moisture. Such a feature may prevent odor and any unpleasant sensations generated by a sweaty run.

Geofit is memory foam, and it’s used for the Adizero Adios 4’s collar. This foam-accommodating feature is tasked with delivering a customized hug that adapts to the exact shapes of the wearer’s ankles and heel. Memory foam has always been touted as a solid choice for those who want guaranteed security and comfort without feeling restricted.

A mix of faux-leather, printed overlays and stitch-reinforcements make up the fit system. These elements work with the flat laces to provide a snug yet adjustable coverage. The stitched portions are holdovers from the very early versions of the Adios series, proving to be helpful in securing the foot and keeping it in place.
