adidas 6692sd5 women boots sale online | old school adidas high tops 12 review

The upgraded old school adidas high tops 12 is a truly impressive shoe, and here's who we think will love it the most:

• adidas homepage.
• Those who are fans of the Boston series but felt let down by the heavier weight of versions 10 and 11.
• Any runner in need of a versatile shoe that can handle all sorts of training runs, regardless of how fast or long they might be.

If you're in the market for a soft, flexible running experience, we believe the Boston 12 might not be your shoe. While it's softer than its predecessor, it still delivers a somewhat firm and stiff feel underfoot. In that case, the adidas nylon tracksuit shoes for women or the Hoka Mach 5 could be better all-rounders.

We also think there are better options if you plan to use the shoe for pure racing or track workouts. It's a bit too heavy for those purposes, and if budget isn't a concern, the Adizero Adios Pro 2 is likely a superior pick. On the other hand, if you're looking for a budget-friendly shoe for fast runs or short races, consider the Adizero Adios 7.

The moment we received the shoe in the lab, we found the Boston 12 noticeably sleeker than its predecessor. However, nothing beats the precision of a caliper for an accurate measurement.

The heel, at 34.5 mm, offers 4.6 mm less Lightstrike EVA foam.

This adjustment by the German brand won our approval, echoing the sentiments of many runners who felt the version 11 was bulky and had excess foam in the heel for what should be a speed-focused running shoe.

On the other hand, the forefoot thickness remains almost unchanged, clocking in at 28.4 mm. This measurement is 0.9 mm less than the previous model's, making it nearly identical.

The 6.1-mm heel-to-toe drop between the heel and forefoot benefits midfoot and forefoot strikers. And the shoe comes packed with even more of the premium Lightstrike Pro foam in the forefoot area than ever before.

However, those with an extreme heel-strike pattern might find the previous model more suited for that foot strike.

Adidas has, for a while, been incorporating the less impressive Lightstrike EVA foam in many of its training shoes. We all found it a bit of a disappointment. However, things are finally changing.

Now, enter the new Lightstrike 2.0. Yes, it's still an EVA-based foam, but it's a whole lot lighter and feels far more bouncier underfoot.

While it's crucial to note that it's not the softest foam on the market—we clocked it at 24.0 HA—it's certainly a marked improvement over the first-generation Lightstrike.

The real standout in this shoe is the TPEE-based Lightstrike Pro. We've delved into this world-class foam in our adidas spezial jumper purple hair. It boasts phenomenal energy return, remarkable durability, and an optimal balance in softness, which we gauged at 18.5 HA in the lab.

This is why the shoe feels notably better underfoot than its predecessors. It packs more Lightstrike Pro than ever, and in a softer formulation, too. Compared to the previous version—the v11, which we measured at 23.5 HA—the improvement is palpable.

EVA midsoles tend to get really firm in cold temperatures, and the Lightstrike 2.0 foam follows this pattern. We measured it at 30.0 HA after a 20-minute nap in our freezer, and we also felt it firmer underfoot.

This 25% firmness increase is a standard result, yet it signifies an upgrade from the first-generation Lightstrike foam.

The Boston 12 felt spacious right from the start, but for us, the key is to measure and extract all the data from every shoe—so let’s dive in.

We created a 1:1 mold of the Boston’s toebox and measured 99.2 mm at its widest point. This measurement far exceeds the average shoe and even surpasses most tempo trainers. So far, the Boston 12 stands out as a promising option for runners with wide feet.

Our second measurement was 73.2 mm, landing right around the average. This reflects Adidas' classic, slightly pointy design, yet it still feels more spacious compared to many competitors.

On the flip side, the toebox volume measured a compact 25.8 mm in our vernier calipers. Combined with the non-stretchy material of this upper, it may feel restrictive for runners with higher-volume feet. That said, this result aligns perfectly with what we expect from a tempo running shoe.

We firmly believe that the Boston remains an impressively stable shoe, especially considering its elevated height.

Through our static tests and fast-paced test runs, we consistently experienced a reassuring sense of balance.

Despite this, the Boston 12 displays slightly more flexibility than its predecessor, and that's a positive change. The reason for this lies in the shoe's Energyrods. The current model uses full-length fiberglass Energyrods, which are not quite as rigid as the combination of a carbon-fiber plate and Energyrods featured in the previous model.

In the shoe's heel, we discovered a counter stiffness more akin to that of racing shoes. It didn't resist our sweater force at all. On a scale where 5 is the stiffest, we'd rate this a mere 1.

Heel strikers might have preferred a rating of 2 or 3 out of 5 to improve stability. But, as we've already mentioned, Adidas seems to have designed this shoe with midfoot or forefoot strikers in mind.

And here's more evidence of this focus. We measured the landing platform in the forefoot of this shoe at a whopping 118.2 mm, providing significant stability for midfoot or forefoot strikers. 

Take the Boston 11, for example. We measured its landing platform at 109.3 mm, which is narrower than most shoes. However, this 12th edition is among the widest shoes we've ever measured.

In contrast, the heel remains moderately narrow in true Adidas style. We measured it at 86.0 mm.

We've mentioned before that the Boston 12 is more flexible, thanks to the swap from a carbon plate to the full-length fiberglass Energyrods. Now, we've got the solid proof for you.

In our test to bend the shoe 90-degrees, it took less muscle force (26.7N) with the Boston 12 than with the average running shoe. This is a complete turnaround from the previous model and a refreshing and welcome change than makes the shoe way more versatile.

And no worries at all when it comes to chilly weather. Our measurement shows we only need a force of 33.3N to bend the Boston 12 to 90 degrees. That's even less than what it took to flex the Boston 11 in room-temperature conditions!

The gap between the two measurements shows an impressive 24.6% change. It's a monumental step up from last year's model, as it suffered a 42.0% increase in stiffness.

Undeniably, the introduction of the new Lightstrike 2.0 EVA foam played a substantial role in this success.

As we just mentioned, Adidas truly excelled in this area with the Boston 12. The shoe now comfortably falls under the 10 oz threshold, weighing in at only 9.2 oz or 261g. This makes it lighter than the average running shoe!

Now, we believe this true Boston model is elephantine to take on its peers in the arena of lightweight tempo trainers like the crowd-favorite Saucony Endorphin Speed 3.

Absolutely AMAZING. That's the best way to describe the breathability of the old school adidas high tops 12, based on our smoke-machine test results in the lab. It earned a perfect score—5 out of 5.

The light test also confirmed this outstanding breathability. The upper's thinness was easily observed as the light passed right through.

After reviewing the upper, we noticed eight well-placed ventilation holes on the sides—an important addition to boost airflow in this often-overlooked area.

To delve deeper, we took out our trusty microscope to explore the shoe's impressive ventilation.

What we found was a remarkably thin and breathable mesh from Adidas. Clearly, there's no need to have huge ventilation holes in the upper with this clever design in place.

We're disappointed that the durability issues we saw with the Adizero Boston 11 persist in the Boston 12, which led us to give it a low score of 1 out of 5.

It's clear to us that Adidas has the technology and know-how to create a thin-yet-robust upper for the Boston 13, similar to what Nike achieved with the Alphafly 2. We can only hope they step up their game for the next release.

To our pleasant surprise, the heel padding proved to be significantly more resilient than we anticipated, especially after the disappointment of our previous Dremel test.

In our usual procedure of applying 3.2N for four seconds at a brisk 10,000 RPM, the Boston 12 stood impressively, demonstrating a commendable level of durability in the heel counter. And the comparison against the Hoka Gaviota 4 speaks for itself. 

Undoubtedly, the most applauded feature of the Boston 12's predecessor was its outsole, a durable-yet-grippy rubber that only a select few shoes can claim to have as of today.

With the v12, we observed some changes. Given the exceptional durability of the Boston 11, Adidas trusted Continental to create a softer compound for the Boston 12 that we measured at 79.8 HC—8% softer than v11 . It's a clear attempt to enhance an already high-performing outsole, and it worked wonders.

But how can we be certain that the durability remains incredibly impressive? It's because we put it through rigorous testing in our lab. We used our Dremel test once more, this time to gauge the amount of rubber that vanished post-abrasion.

The final outcome was nothing short of astounding: despite its softer formulation, the Dremel only succeeded in creating a mere 0.7 mm dent, which is less than the 0.74 mm measured on the Boston 11.

This result shines brightly when compared to the average shoe, affirming the extraordinary durability of the Boston 12.

A common critique of the revamped Boston series—after its longstanding status as a low-stack shoe—has been the increased weight. We fondly remember the nimble and lightweight models like the Boston 9, and the latest two versions felt significantly bulkier in comparison.

adidas foundation grants for college employment:

• Minimize the thickness of the rubber.
• Increase the amount of exposed foam.

Adidas chose the first path, decreasing the outsole thickness from 3.3 mm to 2.8 mm in this version.

We've found this approach particularly effective, and in light of the exceptional durability exhibited by the Boston 12, we anticipate that Adidas might reduce the thickness even more in the next iteration.

Once again, Adidas seems to have overlooked the needs of night runners. The shoe doesn't have a single reflective element, which is a disappointment.

Adidas has really taken a weight-loss approach with the Boston 12, and it seems like the shoe's tongue got a bit too much of the slimming treatment. Now it's half the usual thickness in a training shoe.

We're not big fans of this particular change—the tongue really feels one of the few steps back from the previous models.

In our lab test of the Boston 11, we liked its fully-gusseted tongue, though if we were designing the shoe, we'd have opted for a semi-gusseted design.

Now, Adidas has dismissed the fully-gusseted tongue, which might sound like good news. But they've replaced it with a non-gusseted one. That's a real bummer, especially for a training shoe that sets you back $160.

Keeping up with Adidas' cool design trends that started with the Adizero Adios Pro 3, the Boston 12 sports the same slick, flap-like pull tab on the heel.

We've got to say, we're totally digging this look—it's like having the rear wing of an F1 car right on our heels!

Whether you prefer to use our own orthotics or a different shoe insole, it's no issue, because the Boston 12's insole isn't glued down at all.
