UA HOVR Sonic 2 turns you into flight modeMore photos
I recently purchased Under Armour HOVR Sonic 2 (Black/Orange glitch). I bought this in a UA outlet for a great deal (CAD 60). As of this review, I ran around 60kms on this shoe.
The one biggest concern was sizing. As many mentioned, the sizing is not true to fit.
In my case, the issue is with midfoot width. I would have kept my size 10 if the midfoot has wider options. Thus, I recommend getting a half size bigger if you are shopping online.
Other than sizing, the comfort of this shoe cannot be questioned. The cushioning is so nice you feel like you are turned into flight mode. You will realize this in your very first run.
The outer mesh is breathable that will surely help for long runs. I haven’t logged a long run, but from my 6kms run, I didn’t feel any issues.
The removable Ortholite liner keeps your feet dry and responsive.
With regards to comfort, this shoe is on top of my list. As advertised, UA cushioning feels like zero gravity, and there is no denying this factor.
Design & construction
Construction of the shoe is excellent. In my 50km runs so far, I don’t have any issue with my feet or felt any uneasiness.
Before this Under Armour, I was coming from Asics Cumulus 20, which are slightly heavier (maybe by .2oz) than the UA Sonic 2.
The mid and inner sole of the shoe are very soft and responsive. Your feet are glued into the shoe well and will give you instant comfort without any break-in period.
UA HOVR technology hasn’t failed to live up to the expectation. The responsiveness and energy return are evident from your first use.
The HOVR, as claimed by UA, uses Olefin material, which is a wax-like synthetic that is strong and resilient. If you are a first time UA user, you will notice the difference immediately.
The one thing to note in this shoe is that the heel counter is not having any special padding or cushioning.
If you prefer some support at the back of your heel, then I strongly recommend trying on the shoes before making a decision.
The outsole provides good grip and traction during your run. The solid abrasive rubber under the heel enhances comfort during the ground contact.
During the run
As the title of my review states, this shoe will turn you into flight mode. The HOVR technology provides the zero-gravity feel, which will make you feel like running on the air.
With the smooth stride and ground contact, you might be pleasantly surprised to see improvements to your overall pace, at least in my case, I could see my average pace going up.
The side support and running at a good pace into turns didn’t give any gripping issues. The grip on the road is good. However, I haven’t tried this shoe on non-road surfaces.
I have used this shoe when the outside temperature was ~18-20ºC and haven’t tried in lower temperatures. Considering the design, I am confident they will handle lower temperature runs.
However, don’t consider this for running in winter as the traction and grip might not be great in Canadian winter.
UA connected sensor
These shoes come with an inbuilt UA connected sensor, which tracks and records the run with your shoes. The sensor works without any issues.
Download the UA “Map my run” app from Apple App Store or Google Play store. It also works with Map My Fitness app.
Tap the right leg shoe on the ground, keep them to their sides, and the phone app will be paired with shoes.
I tried to check the metrics, unfortunately, they are not very accurate. But, if you don’t have any fitness tracker, then you will be happy to use the inbuilt sensor.
For those using some fitness tracker, the sensor doesn’t have GPS (if you are Strava user you know it will be treated as indoor run).
I compared the running distance with my Apple watch and inbuilt sensor, and this always recorded longer distance.
For instance, my watch recorded 6.05kms and sensor recorded 6.78kms. It cannot differentiate the run and regular walking.
These shoes come with good color options for different tastes.
My picks are:
- Dust/Summit white
- Wire/Ash Gray
- Black/Orange glitch
- Mod gray/ Jet gray
- Super comfortable pick neutral and daily running shoes
- HOVR technology stands out with its zero-gravity feel, which makes you feel like you are running on the air.
- Suitable for all levels (beginners and serious runners)
What I don’t like
- Sizing is not true to fit. I recommend trying it first in the store before purchasing.
Under Armour SONIC 2 - World record breakers?More photos
I have a confession. Despite regularly purchasing UA apparel and rarely being spotted running around Cardiff without sporting a backward-facing UA cap, it is simply not a brand I have previously considered synonymous with running.
However, when a friend approached me and asked if I would be willing to run a marathon for charity with the added dimension of obtaining a world record, I had little hesitation in pulling on the UA Sonic 2 and putting them to the ultimate test.
- Lightweight and comfortable
- Digitally connected running
- Reasonably priced
- Narrow fit for wider feet
- Cushioning means, you lose some natural ‘feel’ with the ground
- Can lose traction on wet smooth surfaces

First impressions & appearance
The Under Armour Sonic 2's are extremely easy on the eye. Unboxing, my first thought is that these pair of shoe wouldn't look out of place in a "back to the future movie." Thank goodness, RunRepeat didn't send me a blue hedgehog.
The micro-tonal black knit contrasting perfectly with the vibrant neon orange and green midsole certainly has connotations of a shoe that has arrived from the future. The shoe also comes in a range of including black, grey, white and blue.
It is clear that there has been some time and effort in incorporating design and technology into this shoe to make it aesthetically appealing.
It has a thick knit upper that appears to be robust and breathable. The midsole "incidentally" incorporates UA's HOVR technology not only boast a good degree of cushioning, but also allows a good degree of flexion when pulling the toe box towards the heel. This bodes well.
I am aware that looks can be deceiving. However, if we are judging a book by its cover, I can assure you that your first meeting with the Sonic 2’s will at least have you intrigued about what these shoes can offer.
Comfort & fit
It is not every day that I would agree to run a marathon with less than a week’s notice, let alone run it in a brand new pair of running shoes. Neither may I add would I advise any readers to follow suit.
However, when RunRepeat gave me the opportunity to review the Sonic 2, a spontaneous marathon offered an ideal scenario to test the qualities of this running shoe right out of the box.
On this basis, it is a credit to Under Armour that I was able to complete the distance with only one minor issue.
Overall, from a comfort perspective, there are a number of features that make the Sonic 2 an extremely comfortable shoe.
Firstly, the shoe is extremely responsive. The HOVR foam does what it was designed to do which is, in essence, giving back the energy return you put into each step.
The shoe feels relatively light and bouncy, which reflects UA’s claim of a ‘zero gravity’ feel. This is an aspect that my aging knees are certainly grateful for. Any shoe that can reduce impact and give something back in return is a winner in my book.
However, no shoe is perfect, feel, and performance are two different things. The knit itself (while reassuringly study), allows a good amount of movement. You have wiggle room for your toes, yet at the same time, your foot still feels secure within the shoe.
The securing qualities within the shoe are found with little details such as a slightly unique tongue construction. While suitably padded for extra comfort, it is also attached to the footbed by support wings.
Further to this, the TPU heel counter means that your foot is held into place from toe to heel. TPU (Thermoplastic Polyurethane) is essentially a flexible, durable plastic. In light of that, your heel will feel supported, yet with the ability to allow movement.
The only (aforementioned) issue with the comfort and sizing of the Sonic 2 is concerning the fact that as a runner with slightly wider than average feet, the shoes are a narrower fit.
While running a marathon, this meant that I was experiencing some pain as my feet expanded in the heat. I had to stop and adjust the shoe, slackening the laces as much as possible.
Fortunately, as the marathon was run at a relatively slow pace, this rectified the issue. However, be aware that the fit is certainly snug.
The upper consists of a robust micro thread knit that provides a breathable and durable exterior to the shoe.
The complex weave (below) provides a premium quality material. This is versatile in its ability to keep the feet well ventilated in the heat while offering protection from the elements in more inclement weather.
In relation to our marathon quest, as the miles counted down on a sweltering hot summers day, and with a world record in site, my feet were grateful for both the ventilation and the protection offered by this durable and well-ventilated exterior.
Aside to a minor sizing issue (see comfort), how many running shoes with 0 miles within their running life would leave both feet unscathed with neither a blemish nor abrasion in site following a challenging rural marathon?
The Midsole is the engine room of the Sonic 2 and is essentially where the magic happens.
The UA Sonic 2 incorporates UA’s flagship technology in the HOVR cushioning. This is surrounded by an ‘Energy web’ (as you would expect with any shoe with a celebrated cushioning technology this means a relatively standard 8mm heel drop).
The energy web is created from a mesh fabric that wraps the cushioning core. This means that there is highly reactive charged foam ready and waiting to deliver an effortlessly responsive energy return with each step.
Essentially, the energy web does the job of harnessing the energy input by not allowing the cushioning foam to lose its shape. Any impact during the run is absorbed by the foam and instantly returned to the foot in the form of energy.
So in basic terms, what does the HOVR technology mean for the runner and my experience of the Sonic 2 during my marathon world record attempt?
In simple terms, from a running perspective, this means that you maximize the effort you put into each step. When you think the force of each step is approximately 2-4 times bodyweight, the energy return and responsiveness of the shoe cushioning means every stride should feel light and effortless.
Returning to my world record attempt (as a result of the midsole), not only did I feel more efficient as the miles ticked by, but my fatigue levels were kept at bay as well.
The construction of the Sonics 2 encompasses a durable micro thread knit weave upper with a lightly reinforced material lining offering both breathability and durability.
The tongue of the shoe is padded and encased within a robust and easily tied and comfortable lacing system. Within the shoe itself, you will find a removable anti-microbial sock liner for customized comfort and fit.
Below this, the shoe is built around a charged foam midsole containing UA’s HOVR technology which essentially consists of three layers - the HOVR foam itself, the energy web, and the blown rubber outsole.
Further to this, the heel counter adds support to the shoe with the TPU heel counter as per above.
The outsole is an elaborate patterned network of blown rubber which is a lightweight material and incredibly responsive. This adds the overall ‘zero gravity’ feel of the shoe.
Directly beneath the heel, you will feel a reduced impact in each stride due to a high abrasion rubber which helps absorb ground contact.
I did feel a slight loss of traction underfoot on extremely smooth and wet services. However, this is not uncommon in a standard running shoe.
The digital advances in shoe technology have been an interesting development from shoe manufacturers over recent years. It only seems like yesterday that Nike developed a removal chip to communicate with the I-pod.
However, focusing on the UA Sonic 2, is it evident that UA has made advancement in the digital capabilities of shoes that this technology is already built into the shoe?
To utilize UA’S record sensor technology, you will firstly need to download the UA Mapmyrun App on your smartphones.
The digital connectivity between the shoe and the App is controlled via Bluetooth. The chip is contained with the right shoe, and all that is required to activate it is a simple tap of the foot to establish a connection with the App on your phone, and off you go.
The process is relatively seamless the stats such as pace, distance, and time is recorded along with interesting "extras" such as stride length and cadence. It is also nice to have vocal feedback through your earphones as you run.
The only downside is that you have to have your phone while you run to record all of the detailed stats. If you are a more experienced runner, you will find your Garmin stats more sophisticated in managing your training needs in regards to stats.
However, the digital connection is a nice touch and connects you to UA’s world of likeminded runners.
In my view, any shoe that is a record-breaker has to be considered a quality shoe. For me, the Under Armour Sonic 2 are indeed that.
From the perspective of someone who hasn’t previously run in any of Under Armours selection of running shoes, it has been a pleasure to review these trainers.
Every aspect, from aesthetics to comfort, has been considered. Because of that, UA has designed a shoe that delivers a durable, comfortable ride that also potentially improves individual performance due to the effortless response and feel from the HOVR technology.
Personally, I feel that this is a versatile shoe and is essentially a ‘Jack of all trades’ in some senses. Its lightweight design enables it to function well as a faster shoe which is great for those tempo runs, while its robustness and comfort lend itself well to those longer runs where you need to feel a reduced impact.
Interestingly, Under Armour market the Sonic 2 as a faster pace shoe due to the HOVR technology and its light weight.
However, I do feel that because of their versatility, the Sonic 2 are not exceptional at any one particular thing. There are faster, lightweight, and possibly more robust shoes on the market that can outperform these shoes.
That said, from a performance perspective, the UA Sonic 2 delivers exactly what they say on the tin. A lightweight, responsive shoe delivering a ‘zero gravity’ feel and you can’t ask for more than that.
In answer to the question ‘could the Sonic 2’s be record breakers?’ The answer for me in regard to the very pair that I own is an emphatic yes!
From a review perspective, what does this mean?
Well, the fact that this shoe accomplished this feat right out of the box, means that rest assured, this shoe is an extremely comfortable, lightweight shoe with a technology (HOVR) that only adds to your efficiency.
Add to this, the digital connectivity and aesthetic appeal then quite possibly UA is on the road to breaking their own records in the running shoe arena.
As mentioned above, if you are looking for a versatile shoe that has a tick in a majority of boxes, you won’t go far wrong with the UA Sonic 2’s.
The [Under Armour HOVR] Sonic 2 is basically a desert island shoe. It's ideal for almost anything running.
If you're looking for a shoe that will feel light on your foot without sacrificing cushioning, then the HOVR Sonic is a great option.
- The long-distance capability of the first HOVR Sonic is improved in this second iteration, where it boasts of more cushioning and providing a smoother transition. Because of these updates, the Under Armour HOVR Sonic 2 equips the runner with more flexibility while retaining the zero-gravity feel in the activity.
- The HOVR Sonic 2 is readily equipped with the Record Sensor™ that allows the runner to track and measure their running metrics. This is a significant change from the first HOVR Sonic, where Under Armour had released two shoes that differed with the presence of digital connectivity.
- While most of the materials have been retained from the first HOVR Sonic, this new edition delivers a level-up of each feature. For instance, the Threadborne upper—also present in the first version—is made more breathable than ever, promising better airflow and longer-lasting ventilation. In addition, other upper elements have also been improved, both in construction and functionality.
The Under Armour HOVR Sonic 2 claims to be true-to-size, according to their sizing chart. Although reviewers have claimed that it runs smaller than expected, purchasers might want to fit the shoe in store first to ensure an accurate fit. However, the shoe is only available in Medium width; thus, runners who have high-volume feet, or want a looser fit, should consider going a half-size up to accommodate their preferences.
The outsole of the Under Armour HOVR Sonic 2 comes in two portions. First, under the forefoot is a blown rubber. The structure of blown rubber—that is, air-injected—makes the outsole lighter, softer, and more flexible compared to traditional rubber outsoles. These qualities prove to be important during toe-off, as they enable a more nimble and responsive movement, which results in a quicker pace.
Meanwhile, under the heel is a high-abrasion outsole unit made from carbon rubber. The durability and high-resistance characteristics of this material promote optimal shock absorption and better feel of the ground during running.
The HOVR technology of Under Armour is materialized as an ultra-responsive midsole foam that encourages energy return with each step. More importantly (and as its name implies), HOVR provides a “zero-gravity feel” because of its ultra-lightweight and soft qualities. With HOVR foam, the HOVR Sonic 2 effortlessly absorbs impact during running and transforms it into energy. The same capabilities could be said with the Zoom Air feature of the Nike Air Zoom Pegasus 35.
Aiding the HOVR foam is the EnergyWeb, a compression mesh unit that is wrapped around the HOVR foam. This feature maintains the shape of the midsole, as well as augment the shoe’s responsiveness and energy return.
The Record Sensor is the main feature of the Under Armour HOVR Sonic 2 that sets it apart from the traditional running shoe. This unique device comes in the form of a pod that is embedded in the midsole foam. The Record Sensor engages digital connectivity via Bluetooth to allow runners to track their data, as well as offer coaching to improve running metrics.
Similar to the previous iteration, the HOVR Sonic 2 utilizes Threadborne upper material to give a coverage that is breathable, comfortable, and lightweight. Threadborne is meant by Under Armour to be a premium material, having been made from engineered, microsized threads that allow maximum mobility and functionality.
For additional details, there is an external heel counter made from thermoplastic polyurethane (TPU) provides additional support and structure for a more secure run, as well as a unique tongue construction that augments the snug fit of the HOVR Sonic 2.
The Under Armour HOVR Sonic 2 highlights the Record Sensor as one of its, if not the most, significant feature. From the get-go, it is easy to mention that this shoe is capable of leveling up the running experience in a technological aspect. Here we mention how the Record Sensor aids the HOVR Sonic 2 in its performance.
The Record Sensor needs a smartphone or another device that can download the accompanying Under Armour app, which, in turn, allows the user to view the running data being tracked by the device. As the runner wears the HOVR Sonic 2, the device gathers data related to movement, such as steps, pace, distance, and calories burned. These data are stored in the app and can be viewed when the user wishes.
Aside from the HOVR Sonic 2, which is a running shoe, the Record Sensor is also employed in other Under Armour products, like their headphones. The Record Sensor is durable enough to withstand rainy-day runs and it is designed to last longer than the running shoe itself when used properly.
