    Running at Supersonic Speed (well, maybe) in the Mizuno Sonic Racing Flat

    More photos

    The Mizuno Wave Hitogami 4 road racing flat is still with us. However, this will remain true for only a matter of months.

    Will its eventual replacement, the new Mizuno Wave Sonic racing flat, enable one to run at what feels like supersonic speeds?

    See the verdict below.

     

    The Wave Sonic in A Nutshell

    The new Mizuno Wave Sonic is said to be “a versatile road racing flat…” that delivers “a responsive ride ideal for 5K racing to longer uptempo workouts.” (Running Warehouse)

    The shoe has a U4icX Wave – a non-visible foam unit located in the midsole.  The Wave Sonic’s sole is blown rubber, with the exception of a hard rubber X10 segment at the heel.

     

     

    Wave Hitogami.

    At 7.7 ounces, the Wave Sonic is an ounce heavier than the Hitogami. (While that’s not substantive, those drawn to racing flats can be quite picky about weight.)

    The Wave Sonic’s fit is nice and snug (“a sleek, glove-like fit,” according to Mizuno), but one which never feels tight. There’s a decent amount of flex in the forefoot, which will please those with inflexible feet.

     

    Performance

    On city streets and sidewalks, it’s readily apparent that the Wave Sonic delivers a nice snappy ride.

    It is quite stable for a shoe without a medial post; in fact, the straight-ahead ride is comparable to that on the Asics GEL-DS Racer flat (a model that uses a medial post to reduce slight to moderate over-pronation).

    The cushioning is smoothly protective and like other new models from Mizuno, the ride is no longer ultra-firm.

    On a school track, there’s a good amount of ground feel. But an issue quickly raises its head on the oval. The Wave Sonic does not feel as fast as other flats.

    Specifically, it does not feel as fast as running in the Asics Gel-DS Racer or in the Brooks Hyperion. And, frankly, it does not feel as fast as running in the new Mizuno Wave Shadow trainer.

     

     

    Note: These are not your father’s Mizunos!

    The fact that the shoe does not impart a sense of running at supersonic speed is unlikely to affect the fast Cheetahs or Bobcats who almost naturally gravitate toward lightweight flats.

    But it may be discouraging to the mid-pack runner seeking a magical shoe that at least imparts the illusion of speed.

    I think the low heel drop is a major factor here. It keeps the feet anchored close to the ground.

    Those who like more minimalist shoes will be pleased by this, but natural high-steppers and heel strikers may find it to be problematic.

     

     

    The Wave Sonic provides an admirable amount of bounce back, but this seems to dissipate pretty quickly.

    There’s not a sense of forward motion momentum ramping up, as one can readily experience in the Wave Shadow.

    Another factor is that the heel surface on the Wave Sonic is soft and indistinct. It is quite difficult to feel heel plants and this leads to an inability to sense one’s pace in the shoe.

    Cushioning

    While the Wave Sonic provides a fine level of cushioning – comparable to that on the New Balance 1400 v5, it does not appear to be quite as protective.

    I experienced tenderness in my feet on the days after running in the Wave Sonic. Perhaps the Wave Sonic could use an additional half-ounce of foam in the midsole of each shoe.

     

    Durability

    The sole of the Wave Sonic appears to offer admirable levels of durability. However, the heel area looks to be vulnerable.

    It may be feasible at some point to add a patch of reinforcing, tough rubber over the existing X10 heel surface.

     

    Shoe Rotations

    Some runners like to use different shoes for different purposes, using three shoes in what’s called a rotation.

    For Mizuno loyalists, the Wave Sonic is a good choice for a speed training and race day shoe.

    The new Mizuno Wave Sky (11.1 ounces) can be used for recovery days, and the Wave Shadow (8.9 ounces) makes for a superb choice as a daily trainer.

    Non-brand loyalists might augment the Wave Sonic with the Reebok OSR Harmony Road (10.7 ounces) for recovery days, and the Jack of all trades Adidas PureBOOST DPR (9.2 ounces) as the daily trainer.

    Responsiveness – B+

    The Wave Shadow provides what I would term as light responsiveness.

    Stability – B+

    The Wave Shadow is far from lacking when it comes to stability.

    Cushioning – B- to B

    I’ve run in the Wave Hitogami which provides a high level of road feel; so much so that some runners were hesitant to run farther than a 5K in it.

    The Wave Shadow provides enough smooth cushioning to facilitate 10K and further runs.

    Speed – C- to C

    In practice, the Wave Sonic can and will provide those of fleet feet with fast times. But it does not deliver a sense of warp speed. And for some, perception is reality.

    Overall Verdict

    The Wave Sonic is a stunning looking comfortable and well-built racer flat from Mizuno. Although it’s not the fastest feeling flat on the market, it’s very reasonably priced at $100.

    Most runners should be able to use the Wave Sonic on race day for 3.1 to 13.1 miles. Light, naturally gifted, runners may strap on a pair to quickly add 26.2 miles to the odometer.

    Sonic Fast In All Occasion

    More photos

    Mizuno’s new addition to its racing lineup makes me think about my childhood. Wave Sonic makes me remember the video game I used to play and the term I started to use to express things happening at very high speed; “sonic fast”.

    road shoe suitable for short distance races and uptempo trainings.

    The shoe is around 220gr in weight and heel-to-toe drop of 4mm.The pair that I have is in Black and it has a look similar to that of some crossfit shoes. I can easily say that I use the shoe for daily use with a jean and received positive comments from my friends.

     

    Fit

    Shoe size is similar to other Mizuno models I have used. It has a glove-like fit and I believe that thin and seamless upper part plays an important role in this.

    During the run, it feels close to your feet and reacts like a part of your own body. I believe that for fast races and training this is a very big advantage.

    With a low drop, you can feel more freedom on your feet and this freedom can turn out to be a higher pace in your run.

     

    Outsole

    As the other new shoe Mizuno introduced (Wave Shadow), Wave Sonic also has Mizuno X10 carbon rubber as an outsole material. This material is very durable, which is something missing in most of the racing flats. 

    The traction I felt on an asphalt road is good and I believe patterns in the outsole is one of the reasons for this.

    Unfortunately, where I live is not known for perfect asphalt roads. Therefore, even if you run on asphalt, you should expect some foreign materials along the way.

     

     

    With its durability, X10 carbon rubber won’t have any problem with materials such as glass, stones, trash etc.

    More so, due to is low profile, I feel the ground and what’s on it, much more. For long runs, however, this can possibly create minor problems for the feet.

    Midsole

    The new midfoot wave construction with U4icX promise to deliver enough cushioning for long distance.  As a mild overpronator, what I felt on my runs is an elastic feel from the shoe. It's also very comfortable that the shoe has a 4mm drop.

    The same material used in Wave Shadow was used for Sonic giving that similar bouncy, elastic feel.

    I am certain that we will see more usage of U4icX in other Mizuno models especially for the race models as it sure creates some additional speed.

     

    Upper

    Upper unit of the shoe provides a very close feel and Mizuno already describes this as “sock-like construction”. It has a seamless mesh upper, which is also soft and comfortable.

    In general, Wave Sonic has the logo printed which was moved to save some weight.

    I believe that we are living in an era where anything is possible with the help of technology and people are seeking quicker and lighter shoes, therefore any kind of weight saving will be important during a selection process.

     

    User Experience

    Due to my overpronation, I took the shoe only for short runs (4-6km). I am not sure whether it is due to its midsole U4icX material or just because I run on short distances, I felt enough support from the shoe.

    Of course, my feet were much more free to move and when I look at that, while the shoe doesn’t support my overpronation, it was much better than my expectation from a racing shoe

    This is the first racing flat that I used, therefore cannot compare its speed on the road with other models. For me, however, it is a fast shoe and it's elasticity provides additional force during “pull/push” phase.

    As a negative note, in the toe box area, there are more rooms for it to be called“sock-like”. 

    Does it create any problem for me? My answer is no.

    However, I believe that since Mizuno puts emphasis on its specification being sock-like, it needs to be improved.

    For the majority of runners, I'd suggest that Wave Sonic's niche will be between 10K and Full Marathon, with tempo runs and drills also making great use of its strength and structure.

    Overall, I would say that these shoes are exactly as advertised – firm and low to give you that fast speed over short distances.

  • The Mizuno Wave Sonic is a neutral running shoe that’s created to perform on the roads. Unlike most of the brand’s line of footwear, this model doesn’t have a lot of overlays or bells and whistles that make the façade pop. Its simple design allows it to cater to those who have the taste for an all-around shoe that’s simple in form, yet efficient in performance.
  • The underfoot platform is also straightforward in its design and construction. There aren’t a lot of extra components, save for the bouncy wave unit in the midfoot section. The full-length platform isn’t very substantial in size, as well. The external side of the platform has a durable rubber to shield it from wear and tear.

The neutral trail running shoe has the standard running length. It accommodates the regular preferences of consumers when it comes to sizing. It comes in the standard medium width of D for men and B for women, respectively. It caters to those who have medium to narrow foot dimensions.

The shoe’s outsole features the very stylish zigzag-patterned blown rubber. It’s created to hold onto the asphalt with ease and sureness. Also, the strategic placement of the material allows for smooth transitioning of the foot from the toe-off to the landing position.

The midsole unit of the Mizuno Wave Sonic has the U4icX Wave construction, which is responsible for the popular ‘bouncy’ feel, as well as the cushioned underfoot environment. The material is also lightweight, so it’s able to encourage the runners to put extra miles on the shoe on the promise of a fairly inconsequential weight profile.

The U4icX is a full-length foam that carries the foot responsibly throughout the run. It’s designed to have a responsive and springy nature, so it allows the foot to take more energized steps.

The one-piece knit upper of this Mizuno shoe provides a sleek, glove-like coverage to allow for a more natural running gait for the user. Also, the material was designed to deliver a soft and seamless feel against the skin.

The seamless overlays are added to the upper to reinforce the overall structure. These overlays are of minimal weight, so they do not put any unnecessary bulk or heft to the façade of the shoe.

The lace-up closure helps in securing the foot in place. It also prevents any wobbling of the foot inside the shoe.
