The latest Triax is built slightly lower to the ground, making it more stable. The outsole under the heel is further segmented to isolate impact forces and help the foot transition smoothly through the gait cycle. Also, the outsole lugs are thicker, allowing them to compress more and making the forefoot slightly softer underfoot. Recommended for bigger runners with normal arches looking for a soft, stable ride.

The women's Triax is built on a new last that's not as loose in the forefoot as the previous version. As one would expect, it's softer and more flexible than the men's because women are generally lighter. What is consistent with the men's model (left) is the slightly lower heel height for added stability and a softer forefoot. Recommended for women with normal to low arches who want a stable shoe with a good fit.
Here are two comments from users on the Official Nike Blog on the Nike Air Structure Triax :

What three features are most important for you in a running shoe?
Comfort (I need a big toebox), lightweight and style.
What were your initial thoughts after trying it on?
Initially, the forefoot fit seemed tighter than with my regular shoe, especially around the ball of my foot. My toes had less “wiggle room” than I prefer as well. Length felt fine. The heel fit was tighter than I prefer, but provided a good sense of grip and support. Just perhaps too much grip. Overall, I’m not sure if I got a half size too small for my feet. Cushioning was supportive and very comfortable, but snugger than I am used to so I was concerned that I might get blisters. Fit was looser without socks, but this is not my normal running style.
What did you think of the fit and feel after your first run? After several runs?
My first run impression was the same as my impression after several runs–the feel was nice and supportive, both medial (front-to-back) and lateral (side-to-side). I loosened up the shoelaces and the overall feeling of tightness improved, but they were still tighter than I was used to. After my longest run (8 miles) there was some chafing at the back of my heel that would have ultimately blistered on a longer run–this sometimes happens with new shoes, but I think that I probably need a half size bigger.
Is the cushioning adequate? In the right places?
Yes, cushioning was good and properly located and had good road feel, but not too much that I felt that I was being overwhelmed. The “tongue” felt too cushion-y for me, but that’s not really too relevant or important for the overall comfort of the shoe.
What about stability?
I need a stability shoe, and this seemed like it was very stable. I would have had to do a series of long runs over several weeks to truly test it, but I did not feel any sort of shin splints/plantar fasciitis (which is where instability typically shows up on my body) after 10 days of usage.
What is your favorite feature of the shoe?
It was lightweight for the stability it provided. I also liked the graphics and the overall look.
Is there something you would change about it?
Overall narrow sizing– I would size up by a half to a full size to get the proper fit.
How does it compare to the shoe you normally run in?
I have run in my current shoe for three years and am a huge fan, so I’ve got a pre-existing bias that may be unfair. The Nike shoe was comfortable, but too tight in the heel, and I would be concerned that on a hot day (where my feet swell even more) that the toebox would have been too constraining also.
Would you recommend this shoe to a fellow runner or friend?
It’s a well-constructed and well-padded shoe with good style, so I would recommend that a runner/friend at least try this shoe on and compare to other shoes. The narrow fit may not have been appropriate for my feet, but the shoe certainly seemed well-built and worth a trial.

What three features are most important for you in a running shoe?
Fit, support and weight.
What were your initial thoughts after trying it on?
My initial thought was that the shoe felt just right. For the forefoot, I liked the width and height of the toebox. It was roomy, but not so roomy that I was worried that my foot might bounce around too much. As for the length, I can honestly say that these shoes are the the best fitting pair of size 6.5 running shoes I have EVER put on. The heel fit was exceptional. The back half of the shoe felt the most well-fitted for my foot. As for the overall fit, I’m reluctant to say it, but they were almost a perfect fit. I felt like they were custom-made for my feet!
What did you think of the fit and feel after your first run? After several runs?
The first thing I told my friends after finishing a run in the shoes was the I felt like I had already logged 25+ miles in them. They did not require breaking-in whatsoever. (How do you do that, Nike?) I think that was one of the best features of the shoe–they felt like MY shoes not NEW shoes from run #1.
Is the cushioning adequate? In the right places?
The cushioning was great. The back two-thirds of the shoe had perfect cushioning. I might add a little more in the front one-third, under the toebox. It wasn’t really bothersome though.
What about stability?
I have been running in my current shoe for almost two years now and have always been happy with the level of stability in that shoe. I would say the Nike pair I tested were equally satisfactory in the stability department. I think the shoes provided just enough– any more and I would worry about them getting too stiff or heavy and any less I would be concerned about being more injury-prone by running in them all the time.
What is your favorite feature of the shoe?
Oh man, it’s hard to pick one. If I had to chose between the fit and the ‘broken-in’ feeling, I’d say the latter. There’s nothing like putting on a new pair of running shoes and not feeling like you have stiff bricks on your feet.
Is there something you would change about it?
The top of the toe box was REALLY ventilated. I ran in the cold and my toes got chilly. This has never happened to me with other shoes.
How does it compare to the shoe you normally run in?
-Broke them in faster
-More stiffness/structure in the midfoot to heel area. My feet felt more kept in place than my current shoe.
-Not as cushioned in the front, but not to a bothersome extent.
Would you recommend this shoe to a fellow runner or friend?
ABSOLUTELY. I think this might be my new permanent shoe! Loved ‘em!
*Note- I was a plantar fasciitis sufferer in 2007 and have run in custom-made orthotics ever since, regardless of what running shoe I wore. I only ran in the Nike’s with my orthotics.
CONSTRUCTION
The Air Structure Triax is built to mould to the foot and stabilise it kilometre after
kilometre. Using the latest NATURAL MOTION ENGINEERING, it mirrors the foot’s movement
for a smooth level ride from heel to toe.The super supportive footbridge pillars help
prevent over pronation while the air-sole provides generous cushioning.
The dual-density medial mid-sole reduces the peak eversion angle
and the forefoot fex groove pattern helps to engage the windlass
mechanism and encourages natural forefoot movement. Extra stability
comes via the low profle midfoot shank and there’s a foot bed to cushion
each step - from heel strike, through to toe-off. At 334 grams, it’s one of the lightest stability
shoes around.
FIT-SOLE SOCK LINER
The Fit-sole sock liner moulds to the foot in the frst few hours of running for optimum ft and
feel over long runs.
NIKE AIR UNITS
The NIKE Zoom Air units at the heel and forefoot plus the Cushlon ST mid-sole deliver
a smooth, responsive and stable ride.
OUTER SOLE
The Outer-sole is all about taming over-pronation. With an injected Phylon decoupled
lateral crash pad, a cushioned Duralon lateral forefoot and centre of pressure heel design, the
Air Structure Triax insulates the foot against shock at impact and manages over-pronation
in a smooth and natural fashion. Runners may not be the most stable people on
earth, but thanks to the lightweight, stable and cushioned ride of Air Structure Triax, they can be.
WOMEN
The NIKE Women’s Air Structure Triax+ 11 is designed specifcally to ft women’s feet - a
comfortable forefoot and a ftted heel provide the stability female runners need. These shoes
are ideal for the female runner who looks for a shoe that places priority on countering
adverse over-pronation while also providing a lightweight cushioned ride.
The support offered by Women’s Air Structure Triax is suited to female runners looking for
a shoe that gives them more mobility and fexibility on longer run days. It addresses
pronation in all areas - velocity, degree and duration. This is done using a frm ft-frame
heel counter to secure the heel in place, a radiused crash pad to slow pronation and
deep Barefex forefoot fex grooves to engage the windlass mechanism during midstance to
help resupinate the rearfoot. In the mid-sole, a frmer density foam on the medial aspect
resists deformation while in motion and limits the degree of pronation during midstance. This
dual-density foam is also more fexible than the men’s version, as women’s feet are more mobile
than men’s.
Introducing the Newest Zoom Structure Triax+
For those of us (and there are many of us out there) who tend to overpronate in our stride while running, we need a running shoe that gives us the right amount of stability to help correct this problem. However, one shouldn’t have to sacrifice cushioning and comfort for stability. And that is where the new Nike Zoom Structure Triax+ 12 comes in.
As one of the best (and most popular) running shoes for the runner who tends to overpronate, the Zoom Structure Triax is back, and better than ever, with new improvements that not only benefit runners, but also the environment!
With advancements made to both the Men’s and Women’s shoe, the newest Zoom Structure Triax gives your feet the amount of stability they need to help curb overpronation. The Men’s shoe features a fitsole sockliner that molds to the shape of your foot for a custom fit, improved underfoot support and a softened arch—meaning it accommodates a wide range of foot types. The Women’s shoe includes the women’s-specific QE-17 fit to help mold to the unique shape of a women’s foot.
To help combat overpronation, both the Men’s and Women’s models include significant improvements. First, an arch bridge enhances support and medial stability. This allows a degree of torsional rotation to unlock the foot’s natural stabilizing mechanisms. Additionally, an articulated, high-density medial post along the midfoot and heel works with the footbridge and the arch bridge to reduce excessive pronation.
The exterior of the shoe features large expanses of open mesh for enhanced comfort and breathability. Both the Men’s and Women’s shoes also have Nike Zoom units in the heel and forefoot that provide a low-profile nature to reduce the rate and range of overpronation and add responsive cushioning for the ultimate ride.
If all these improvements weren’t enough, the Zoom Structure Triax+ 12 features environmentally preferred rubber along with the use of recycled content—this is the most sustainably engineered version of the Zoom Structure Triax yet!
Not a lot has changed in this update, which is a good thing since it has consistently offered a comfortable ride and an excellent stability-to-weight ratio. Nike reduced the number of overlays to make the forefoot more accommodating, yet managed to keep the fit consistent. These new overlays are made out of more pliant material. Many of our testers commented on how much they liked the upper fit. Recommended for runners with normal arches looking for a firm yet comfortable ride and moderate stability.
