Nike Winflo 12: análisis y review

The Nike Winflo 12 is:

• Perfect for runners who like the new Vomero line but want to spend much less money.
• Ideal for heel strikers seeking a well-cushioned, comfortable, and stable daily running shoe.
• A better value than the Pegasus for many runners, offering more bounce and shock absorption at a notably lower price.

We found in the lab that the new Winflo 12 changes direction and no longer feels like a classic daily trainer, instead moving into max-stack territory. If you prefer a more traditional feel, we believe there are better choices like the Adidas Duramo Speed 2 or the New Balance Fresh Foam 680 v8.

We also think the Winflo 12 is not the best option for runners who hate heavy shoes. We found that version 12 still carries a hefty build, and for a lighter alternative we recommend the ASICS Gel Pulse 16.

Nike has repositioned the Winflo with the 12th edition, and instead of being a cheap Pegasus like v11, it now feels more like a cheap Vomero. However, the design can be misleading, as it clearly borrows from the Pegasus Premium.

Why do we see it as a cheap Vomero? Based on our lab testing, it's clear that Nike went maximalist with this shoe and added a lot of foam underfoot, now reaching 139 SA in the heel and 112 SA in the forefoot. That sits much closer to the Vomero 18 than to the Pegasus 42, and it marks a big jump from the Winflo 11.

We have good news regarding energy return: the Winflo 12 delivers a very nice 8% jump in bounce over its predecessor, now reaching 61%.

This was a bit unexpected, but fully welcome. Getting this level of bounce at a value-friendly price is something not many shoes offer, and Nike adds another strong reason to consider this model over a pricier one.

The Winflo 10 had a heel stack height of 33.5 mm. The Winflo 11 increased to 37.6 mm. Now version 12 jumps to 40.9 mm, making one thing very clear: running shoes keep getting taller every year.

However, Nike kept the Peg 42 at a more moderate stack height of 36.0 mm, and that is why we now see the Winflo as a beginner-friendly Vomero. It sits much closer to that model and stands noticeably taller than the Pegasus.

The forefoot grows accordingly, otherwise the drop would have been excessive. Here we measured 30.3 mm, further confirming the Winflo 12 as a maximalist shoe... and one of the cheapest you can buy by far!

Nike states in the spec sheet that the Winflo 12 retains the familiar, heel-striker-friendly 10 mm drop of its predecessor. We found only a very small variance by measuring 10.6 mm, so everything feels just as expected for anyone coming from previous Winflo models or other Nike daily trainers.

With the Winflo 12, you get more foam, and it also feels softer underfoot. That is what we clearly noticed during our runs and what we confirmed once we returned to the lab.

Using our Asker C durometer, we recorded a softness score of 28.3 AC, down from the 33.2 AC measured last year. As you can see, it also sits well below the average, so get ready for a plush feel underfoot, as that is exactly what Nike delivers here with the Cushlon 3.0 foam.

Nike has worked on the geometry of the Winflo 12 to adapt the rocker to the new stack height, making it a bit more dynamic for heel strikers.

It is still far from being a heavily rockered shoe, and we like that given its versatile role for daily use, with just the right amount of curve in the forefoot and nothing more than necessary.

We found that the Winflo 12 brings a very important change from version 11. Nike has ditched the full-length Air unit in favor of a heel-only design, and given the energy return results, it seems like a smart decision.

In fact, we think that Air should be fully ditched from the Winflo series. It only adds weight and complexity to the manufacturing process, and it is clear that this basic Air unit, different from Nike’s more advanced versions, is not worth the trade-off compared with using foam alone.

In the last few years, we’ve noticed that Nike is moving toward a more accommodating fit. Nothing extreme, but a bit more room than in the past. Using our method of creating a gel mold of the shoe and taking measurements, we wanted to see if that trend holds true for the Winflo 12.

Starting with the first reading, we found 98.0 mm. That is a very generous result and one that was hard to find in Nike shoes from the past.

But the toebox remains tapered, clearly using a classic last shape. With only 72.6 mm, it offers average room for toe splay.

We also found that the vertical clearance of the toebox sits near the lower limit.

With a measurement of 24.4 mm, it does not feel very restrictive, but those who prefer more room in this area will need to look for an alternative in our interactive chart.

Traction is an area where Nike has often struggled with its lower-priced running shoes. However, this is changing too, and we are happy to see it.

The outsole of the Winflo 12 did a good job on wet concrete in our lab test, earning a 0.55 result that outperforms version 10 (0.38) and version 11 (0.42) by a clear margin.

We found that black rubber patches cover the main contact zones of the outsole, and Nike clearly prioritized durability here, even at the cost of adding more weight to the shoe. While Nike seems to be moving away from the iconic waffle outsole in some models, we still found clear inspiration here from Bowerman’s classic design.

In fact, this is one area where the shoe still feels more old-school than modern, as the current trend leans toward using more exposed foam to reduce weight.

The Winflo 12 remains below average in our longitudinal stiffness test at 13.5N, which is a positive result for a shoe designed to perform well on easy runs and in daily life, serving as a true workhorse for everything.

Weight is the biggest deal-breaker for the Winflo 12. It is even slightly higher than its predecessor and now tips our scale at 10.6 oz or 301g, which can feel heavy for runners used to lighter shoes.

The challenge here is that Nike cannot move this shoe to a lighter foam technology if it wants to keep the price affordable, and using less rubber coverage on the outsole may disappoint those who value durability more than a lighter feel. A tough decision for version 13.

Breathability looked very promising based on the design of the Winflo 12, as the upper is packed with ventilation holes. However, we do not like to guess results, so we turned to our lab tests.

We gave the Winflo 12 a 4/5 score for ventilation, which is a very strong result and excellent for year-round use. It offers some protection in winter without feeling too warm in summer, especially in this white colorway.

Shining a powerful light through the upper helped us identify where the shoe allows the most airflow, and the tongue and toebox clearly stand out. On the other hand, we found the lateral side much more structured, adding extra support.

The upper uses a standard mesh design that does not differ much from many competitors.

However, there is a reason why we see similar uppers so often in this price range, and that is cost-effectiveness paired with solid ventilation.

Like in previous Winflo models, Nike clearly wanted strong airflow in the front while keeping generous padding in the heel, making it even more comfortable than many Pegasus versions.

The Winflo 12 feels surprisingly stable despite having a softer foam and more stack height. How is that possible? There is a very good reason for that.

The Winflo 12 keeps a good amount of torsional flexibility, something we confirmed with our custom-made machine that lets us twist the shoe in both directions. We needed 12.5 Nm of torque for that, which is lower than average.

The heel counter is also more or less in line with most other daily trainers at 3/5, so it cannot explain the stable ride we felt earlier. Then what is it?

The main reason behind the stable ride of the Winflo 12 lies in its midsole size. The oversized dimensions in every direction were confirmed here in the lab with a 122.2 mm forefoot measurement.

That is fully in line with maximalist running shoes and feels far removed from the classic Pegasus ride, which is more nimble and carries less bulk. This is a tank!

The heel is even more impressive with 104.4 mm of width, a huge jump compared to the 84.6 mm measured in version 11. That is wider than many stability shoes and makes this area extremely stable for rearfoot strikers. At the same time, it makes the ride less agile and the shoe a bit bulky. 

In HOKA terms, this shoe now feels more like a budget Bondi 9 instead of the Mach 6-like character it had before.

The toebox material is definitely comfortable and soft, but that comes with a price. Durability sits on the lower end, with our Dremel tearing through nearly everything it touched. Unfortunately, that results in a 1/5 score.

This is the complete opposite of what we found in the last test, as here the Winflo 12 did an excellent job and showed outstanding resistance, earning our maximum score of 5 out of 5.

The rubber did a pretty good job against our Dremel, holding up well and losing only 1.0 mm of material. That is a clearly positive result.

With 3.3 mm of outsole thickness and our previous findings, you can definitely expect top-tier durability from the Winflo 12. And that is critical, because buyers of budget running shoes often expect greater durability than those choosing more expensive options like super trainers.

We discovered that the insole adds 4.1 mm of cushioning to the overall setup of the Winflo 12.

The insole is one of the parts where it becomes very clear that the Winflo is an entry-level series for Nike, as we found it fairly basic. Luckily, you can replace it if you want.

The Cushlon 3.0 foam gets the job done, but it is still a basic EVA foam. That is why it showed a big change in softness after spending 20 minutes in our freezer, reaching a 30% difference.

It is always nice to find reflective elements, even if they are small. But can you imagine how cool it would be if Nike’s famous Swoosh logo were reflective?

The lacing system of the Winflo 12 uses a hybrid approach that mixes punched eyelets at the top and bottom with two lace loops on each side. That is not by coincidence, as it is a proven setup to reduce pressure in the most sensitive part of the instep.

The tongue thickness has changed too. We measured only 4.5 mm with our calipers, and while it still feels comfortable, it no longer delivers the plush feel of the past version. This is likely a trade-off made by the designers to add more foam without adding too much weight.

The tongue is semi-gusseted, which is a fantastic bonus given that many shoes in this price range completely skip this feature.

The heel tab also mimics the design of the Pegasus and features an extended heel collar that is very easy to grab when sliding your foot into the shoe.

We found that Nike made another small price increase to the Winflo series, although in this case we think it is fully justified given the improved features it offers. That said, it better stop here or it risks climbing too high and leaving the budget running shoe category.
