Adidas adizero FG Synthetic Review

Adidas adizero FG

Finally, the review you have been waiting for, the Adidas adizero! First off, I have to tell you that I was extremely skeptical going into this review. After testing several other speed boots (Nike Superfly and Puma V1.10), there was one question on my mind: “How bad are these going to blister my feet considering how light they are?” The one thing I have learned is that taking away materials produces a less comfortable boot, primarily because whats left behind is a skeleton frame designed to rub against your heels and toes! But what you will be surprised to hear is that things are a little different when it comes to the adizero! Adidas have truly pulled out all the stops in creating a boot that just downright destroys it competitors in terms of lightweight releases!

The following review is for the synthetic firm ground version in the range, with the leather and SG reviews to follow also. For testing, I wore a size 9US in the Sea of Yellow, Black/Sun/Metallic Silver colorway.

Does the adizero actually feel lighter?
Without having to think about it the answer is “YES.” When I took these out of the box for the first time they blew my mind! It is absolutely astounding how light these feel. I have to admit that I am normally skeptical of lightweight boots, and have stated that I never really notice a difference in terms of weight, but the adizero completely changed my opinion. They are light in your hands and light on your feet!

Breaking In
One of the most surprising things about the adizero is actually the ease with which they break in. The boot comes with 2 different inserts, a lightweight and a comfort. My first piece of advice is to start off by using the comfort version. There is only a slight difference weight wise in both versions, and the comfort version will offer more protection for your fit as you try to break these in. I only had to wear these in one training session before they were ready to be used in a game, exactly what I did not expect! So far I have used them in 3 games, and they have performed extremely well. I did start to feel some slight discomfort on my heels, but after simply applying a band-aid, it never became an issue. All-in-all, I have worn them in 3-4 training sessions and 3 games with very positive results.
To recap: If you have the right size (like I did) you should not experience too many problems breaking these in. Make sure to start out using the comfort insert.

Sizing is an area that I usually stay away from, but I think it will be particularly effective to compare my sizing to the F50i and Superfly ranges for comparison. I have read several comments from people who state the adizero fits a half size bigger. My opinion is not such. I normally wear a size 9, and for testing the adizero I wore a size 9 that fit absolutely true to size length wise. Now, the one area that these are a little different is in width. Compared to the F50i (which I am currently reviewing) or the Nike Superfly II, the adizero fits a little wider and it has a lot more give. One of the biggest contributing factors to this is the fact that the materials used in the boot are so much thinner, giving you that extra bit of space for maneuverability.
My advice: If you fit pretty close to the tip of the toe in a size, go with that exact size. But if you normally have a decent amount of room in a size (about the width of one finger) order a half size down.

What makes this boot super light is the use of Sprintskin, a single layer synthetic that allows Adidas to dramatically reduce the weight. The material is literally as thin as a few sheets of paper! Adidas also use innovative internal TPU support bands inside the Sprintframe (the gray ladder design inside the boot.) It is basically designed to provide additional support and strength to the walls of the cleat. Another area where Adidas have placed additional research is in the stud configuration. The design is completely different to anything else on the market, especially since the studs are a triangular shape! Adidas state that the design helps improve speed when you push off the ground.

A few months back when I saw the prototypes of the adizero range I was not impressed. They seemed to look very square and minimalist. I was particularly put off by the designs used. But after having these for a few weeks, my reaction is completely different. Actually having the boots in your hands gives them a very different look, especially the Messi Chameleon version. No picture actually does the design justice. The soleplate of each version looks very minimal, especially since the only change isAdizero raised heel the stud color. I personally like this aspect as it shows Adidas have placed higher value on performance instead of how the boot looks. One of the more unique aspects of the cleat lies on the heal, where Adidas have replaced the regular wide grooved heel with a much smaller, yet extremely comfortable, thumb heel design. By thumb heel design I mean it literally is a thumb width in size and it extends slightly higher on your heel than it normally would. I like this part of the design as it gives that extra bit of material to keep the boot close to your foot, without adding any extra pressure in the region.

This is one of the few reviews where I have limited negatives to report. I found the adizero lives up to expectations. For a lightweight boot, they offer great comfort and support. In saying this, there is no doubt that like any other lightweight boot out there these will not suit certain players and will cause certain discomfort. This is just part and parcel of what you can expect from a speed boot that has less material/paddding, and of course it all really depends on the player. If I do notice any negatives over the coming weeks I will update this section.

Adidas really have stepped it up with this release. I was highly skeptical going into testing, but all I have are positives to report about the adizero. The look good on, and feel pretty good to wear. It amazes me how Adidas are able to produce Adidas F50 adizero reviewsomething that weighs under 6oz. Even after you read this, you will be astounded at how light they are. And the best part about it is that Adidas have priced these at a pretty decent $200! Considering the market, and what you are getting with these, that is a reasonable price. In terms of position, if you feel like you need a lightweight boot then these might be the best option out there! To be honest, they might not be suitable for defenders who like to get stuck in as they really don’t offer a great deal of protection. This also goes for hard-hitting midfielders. When you are creating a boot for a player of the caliber of Lionel Messi you really have to get it right, and fulfill their exact needs. In my opinion, that is exactly what Adidas have done with these.

    Great review!
    I am really surprised that they got a better grade than your favourite adipure!
    I can’t wait for the leather review!
    It seems that adidas has done a very good job and came out with a winner!

  2. Alex says:

    Hey Bryan,

    Awesome review! I just wanted to ask a few questions like

    Are these cleats good for wide footed people?

    How is the durability of these cleats?

    Are these cleats good for center midfielders?

    And finally can you get good swerve with these cleat?

  3. Rosslee says:

    Bryan great review! I was just wondering about what looks like Jabulaniesque grooves in the last picture above. Do they serve any purpose or are they even significant in any way? I mean it seems odd that Adidas would put groves in the same sweet spot area as on Predators. Anyways great review can’t wait for the leather one!

  4. Danny says:

    Hey Bryan, was looking forward to this review and I must say it’s very good! I was wondering though, what exactly is responsiveness

  5. Matt says:

    Bryan, great review for a great pare of boots. Im in shocked (in a good way)that you ranked them higher then your beloved adiPure III’s. Anyway I was wandering how the stiffness of the upper is in comparison to the F50i’s and the superfly II’s.Thanks

  6. eric says:

    So the soleplate is actually wider than that of the f50i? It doesn’t look that way in the pictures…

    And how’s the touch? I’ve heard from some that the thin materal makes your touch like when you play barefoot or with socks. I’m reluctant to buy synthetics, but i might be convinced with these if this info is true.

  7. J says:

    Yup, thanks very much Bryan. I waited for this review, I am so getting this. I hoped that these fit snugly since I have narrow to medium sized feet. I’ll let you know.

  8. bryan says:

    Thanks for all the comments guys! Hope I cover all the replies!

    Leather review with pics will be up by Tuesday latest…promise!

    They do fit a little wider so should be suitable (I have a medium/wide foot)…I used them in 3 trainings and 3 games with no scuffing or damage, long term I can’t really comment….it depends on what type of midfielder you are, if you are concerned with protection then no, but if you are a playmaker yes…swerve is decent with these!

    Great spot with the “Jabulaniesque” grooves (what a word). They line the synthetic version, not the leather. They are there to aid in touch just like with the Jabulani, they serve a purpose and that is grip. These grooves also exist inside the lining of the boot, alone the ankle and heel region, also to ensure they grip to your feet. Excellent comment!

    Responsiveness is how the boot performs over time, especially between breaking in and games. I watch out for things like how the upper feels on my feet, especially when touching the ball. I also like to know how they perform in different scenarios, when I twist/turn do they feel like they are moving how i need them to. Basically, how do the boots respond to what I expect while I am wearing them!

    I was shocked myself…but these really offer something unique to the market. Compared to the F50i and the Superfly, these boots break in a lot easier and are no way as stiff! Remember, the issue with the Superfly is that the Flywire doesn’t allow the upper to stretch.

    It is not the soleplate that is wider, rather the fit of the upper. I will compare images between post in an upcoming review. I personally felt like the touch was fine and I didn’t feel like I was playing barefoot at any stage. If you prefer the leather, wait for the upcoming leather review, the boot ranks just as high.

    Glad the review helped, let me know how they turn out!

  9. Jason says:

    Are these okay for GKS?

  10. Stephen says:

    Great review Bryan i knew theres a reason i wait for your reviews before i buy my boots but still gonna wait for the leather review as there must be a reason all the pros are wearing the leather version even players like robben and swp who previuosly work the sprintskin F50i’s

  11. Per says:

    Great review. I have wide foots so I think im gonna buy the leather ones. But I decide after ur leather review.

  12. Eli says:


    First off, thank you for taking the time to review this boot.

    I should be getting my pair of adizero’s today. I bought both synthetic and leather version. I will be keeping one. I ask if you have any opinion on the matter.
    For comparison, I hated the F50 tunits ( I don’t have wide feet but they hurt me like a MF), don’t like last years predator model (felt too heavy), and I absolutely love AdiPure II’s (got 3 pairs of the same boot just before they got discontinued LOL)

    Any recommendations as to which I should keep?

    Also, I’m really afraid to break them in and then realize they are too big. I wear 9’s in all my other boots, (all the above + old Nike T90’s). With all the talk about being half a size big. Will I notice it right away on both leather and synthetic or will they stretch over time like my adipure’s?

    And is it true all the footballers will be wearing the leather versions??

    Sorry for the many questions. I will wait for tomorrow’s leather review but I still prefer to ask for a more personalized opinion.

  13. Mus says:

    Hi, Bryan
    Some people said that when somebody stepped on you while you are wearing adizeros, it can hurt you really bad.

    Just want to know, is it true?

    Thanks in advance! :D

  14. Nate says:

    I love your reviews.
    I don’t know if I should get the PUMA Powercat or the Adidas adizeros. I play offensive/attacking midfield on a highschool team. I am a small player who dribbles alot to put together plays. I also like to take long shots from twenty/thrity yards out. I have enjoyed kangaroo leather on the old predators and I also have enjoyed the lightness of the vapor V. I noticed that both the Powercat and the adizero both got great reviews from you.

    Which cleats would you recommend? If I should get the adizeros, which ones (leather or sprint skin)? Do you know how durable the leather version is? Can you feel much of a difference in weight between the leather version and the sprintskin version of the adizeros?

    Sorry for all the qustions. But I would love to get a response.

  15. Matt says:

    Hey Bryan, I’m going to order a pair of adizero’s online but I’m sure if I should get the synthetic or leather version. I like synthetic just as much as I like leather so it’s 50/50. Please let me know what you think I should get. Thanks.

  16. Jade says:

    Hey Bryan,

    Are you going to have a contest/giveaway for these boots?!

  17. bryan says:

    For all the leather versus synthetic questions, I have posted a review covering the topic!
    Adidas adizero: Leather Versus Synthetic

  18. Danny says:

    I found this review and all the others on this site very helpful in deciding to buy a new shoe so I’d like to post my experience and comments about the new adizero synthetic here.

    I have played soccer for most of my life through highschool and college club level as a center middfielder and am used to wearing standard k-leather copas so the decision to try out a new style and material was a big one for me but I figured it would be fun and it is getting harder to ignore the new technology coming out these days. Plus I’ve always been a fan of adidas cleats. I was mostly worried about sizing and changes in ball control/touch going from leather to synthetic. So with that in mind after wearing them for 2 games with one training session in between…

    With regard to fit/sizing I normally wear a size 10.5 in copas and I have an average width foot with good arches. For me that gives me about half a thumb between my big toe and the tip of the boot before they’re broken in. The synthetic adizero size 10.5 gives me probably less than a quarter thumb from the tip of my toe to the end of the boot (almost zero, an exact fit). I was hesitant about this since I’ve read the synthetic won’t streach like the leather and I already have black big toe nails, but I also read and was told it will still mold to the foot so i figured my toes might take some punishment while breaking in but I would get the skin tight fit I wanted eventually. After 1 game and 1 training session I can say here that the sizing was right for me and the sprintskin synthetic yielded to my toes (quicker than I thought it would). I’m very happy about that since spending 200 bucks and getting the wrong size would suck.

    With regard to comfort, Bryan is right about there being zero blistering. My only problem was stubbing my toes whenever I cut and changed directions quickly for the first game and training session. That was kind of painful and probably could have been avoided by buying half a size bigger but that’s just my preference. Bryan is also right to suggest using the comfort insole. I tried using both the comfort and the performance and there really is more support and not a noticable weight difference from the comfort. Wearing the performance insole kind of made the muscles in my feet cramp uncomfortably if that makes any sense.

    Finally, going from leather to synthetic the touch wasn’t too different. Not really better or worse but but the synthetic felt a little more springy off the ball. If you need the leather to make your touch soft I wouldn’t recommend using the synthetic but I have a lot of experience so I welcomed increased response. I think either the grooves on the synthetic, material itself or maybe it was just the clean striking surface with the laces up the side increases shot power and swerve/spin on the ball noticably because my first haphazard shot on goal from outside the 18 I took just to test them out dipped like crazy over some defenders losing none of its power gaving the goalie some real trouble. If I had taken the same shot wearing copas I know the results wouldn’t have been the same.

    Some interesting notes. I know some professionals are saying the brightly colored shoes gets them the ball more because they’re more noticed. I got the chameleons, which are pretty flashy in real life, the pictures don’t do them justice, and I actually noticed things I take for granted from experience like where my feet are spatially related to the ball. I wonder if anyone will do a study on shoe color with relation to eye foot coordination. Also, the sprintskin2, being waterproof now as I understand it had an interesting feel while I was training one morning. The normally heavy/soaked feeling a leather shoe can sometimes get from it raining overnight or the morning dew was replaced by a cold sensation coming through the sprintskin2.

  19. Lucas says:

    Just picked up a pair of these yesterday, and they are insane! It’s true that you really have no clue how light these boots are until you have one of them in your hand! Thanks for providing a review that is extremely accurate.

  20. Per says:

    Im sorry for asking. But when is the leather review coming m8?

  21. zalat says:

    i think that is a very bad review and plz learn something from nike because its always the best in everything:P

  22. Nick says:

    Hey does the “Jabulaniesque” grooves actually help with controlling the ball and adding spin to the ball when shooting or is it just decoration

  23. Tyler says:

    Hey, Bryan
    I have been on the market for a new boot and I can’t tell which is better between the adizero and the Nike Mercurial Vapor. Im looking for a fast shoe with Comfort and touch elements.


  24. bryan says:

    The grooves do offer some grip enhancement, but if it actually helps add spin on the ball is yet to be seen. Without them there, the boot would be very smooth and touch would be more difficult.

    Both the Mercurial Vapor V and the adizero are great options if you are looking for a fast shoe with comfort. The adizero would be a better option if you want the most upto date speed boot.

  25. Per says:

    When is the leather Review conmng???

  26. Sammjds says:

    I bought the leather version of these a week ago & love them. In the process of still breaking them in but I have worn these in a full match & some training sessions. I play Def. Midfielder so even though these are designed for all the tricksters they still work for a lot of different positions on the field.
