Adidas cloudfoam racer tr đánh giá

Inspired by the strength and flexibility of trail running shoes, adidas’ CF Racer TR are casual shoes with superior wear resistance and ample utility for walking around town or doing errands during the day.

A Cloudfoam midsole generates a light, adaptable cushioning that provides great comfort and stability to your walk. The rubber outsole has anti-slip reinforcements on the sides to increase these shoes’ durability.

On their upper, a seamless mesh covers the foot like a glove, providing great softness and breathability at all times. adidas’ classic 3-stripes are applied to the midfoot in the form of thermo-sealed reinforcements for increased support, while tongue and heel straps make it easier to put the Cloudfoam Racer TR on.

If you're a forefoot or midfoot striker, you might want to look elsewhere—this shoe doesn't offer enough cushioning in those areas as it's designed for heel strikers. If you're in the market for an affordable running shoe suitable for those footstrikes, we recommend checking out the Saucony Axon 2.

Also, for serious runners looking to log heavy mileage or intense training, be aware: the Racer TR21 won't meet your needs.

It's clunky and lacks responsiveness, making it far from the ideal training partner. And despite its potentially misleading name, don't consider it if you're in the market for a dedicated racing shoe. For that purpose, we feel that the Adidas Adizero Adios Pro 3 is a better pick.

Breathability

While the TR21 isn't strictly a running shoe and you might expect breathability to be somewhat compromised, we found its performance to be okay. It doesn't measure up to top-tier shoes like the Saucony Triumph 20 in this aspect—the video speaks for itself—yet it's good enough to earn a standard 3/5.

The smoke-pumping test results were particularly surprising. When we held the upper to the light, it didn't appear breathable at all, seeming more akin to a 1/5 or 2/5 running shoe.

Our microscope examination provided the same impression. Besides capturing some stunning close-up images, it confirmed the TR21's knit upper as thicker than average.

Despite this, we must commend Adidas for their effort, even though this shoe falls below the average in our test results.

Additionally, we should spotlight the upper's layered construction. This feature impresses as it boosts comfort, albeit at the expense of breathability. Keeping all these considerations in mind, scoring a 3 out of 5 here is indeed a great achievement.

Durability

Toebox durability

As we noted earlier, the TR21 is equipped with a knit upper. This comes with an advantage; knit typically elevates comfort. However, its downfall is a considerable lack of sturdiness, so we were ready for a disappointing outcome with threads flying everywhere.

Once we engaged the Dremel on the upper, spinning at 10K RPM, our fears were quickly confirmed. The TR21 was on a direct path to securing the lowest of scores: a 1/5.

Still, that's no justification. Other knit shoes, like the On Cloudswift 3, have truly excelled in this same test.

Adidas played it safe with the outsole hardness on this model, with our measurement with the durometer showing it at 80.2 HC.

Outsole durability

For our final test, we used the Dremel once again to evaluate the outsole's durability. Some Adidas shoes typically perform well in this aspect, thanks to their use of Continental rubber, but this shoe lacks that compound. As a result, it offers only average durability.

Who enjoys running around with brick-like shoes? We assume the answer is, not many!

That's why the TR21 weight of 11.20 oz (318g) doesn't seem all that appealing.

The forefoot, however, falls really short. We measured it below 19 mm, which is extremely low by today's standards, and makes this running shoe a bad choice for any forefoot striker.

Drop

Adidas' official specifications give the shoe at a 34/26 mm stack for an 8-mm heel-to-toe drop. Yet, it's not uncommon for us to find discrepancies between the brand's stated measurements and our own.

With the Racer TR21, our meticulous measurements in the lab returned a 31.9/19 mm stack for a 12.9-mm heel-to-toe drop. That's almost a 5-mm difference from the numbers from Adidas. WOW.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measure means it's firm.

With a midsole softness measurement of 21.0 HA, the Racer TR21 delivers a well-balanced experience.

It's not excessively soft or squishy, and it's not too firm either.

Difference in midsole softness in cold

We tested the shoe's performance under cold conditions by putting it in our freezer for 20 minutes.

Now, we can confirm that with a hardness of 28.3 HA, it's close to being considered firm, nearly reaching the 30 HA mark.

Given its $75 price tag, we expected this shoe's performance under cold temperatures to be subpar. This is typically the case with EVA-based midsoles.

So, the 34.5% increase in hardness didn't disappoint us too much. In fact, most shoes in this price range perform significantly worse.

Stability

Lateral stability test

The moment we slipped our feet into the TR21, we immediately felt its impressive stability. What a pleasant surprise!

Torsional rigidity

The shoe appears and feels flexible, yet when it comes to torsional flexibility, it's fairly average, leaning more towards the firm side and we rated it at 3/5.

Heel counter stiffness

Adidas didn't took any risks designing the heel counter in the Racer TR21. It's not the usual super-soft heel because there's some resistance, primarily from a plastic piece that surrounds the area.

We rated it as a 2 out of 5, which in our view strikes a good balance between preventing heel slippage and maintaining comfort.

Midsole width in the heel

However, there's something interesting happening with the heel. We initially suspected that this shoe was designed with heel strikers in mind, given the large heel-to-toe drop and its very low forefoot stack.

This became even more evident when we measured the heel at 95.0 mm—wider than most shoes—which promotes stability for heel strikers.

Flexibility

Stiffness

We mentioned earlier that the shoe seemed flexible at first glance, but it didn't show that much when we tried to twist it. It's during the 90-degree bending test that the shoe truly astonished us with its flexibility.

We only made 13.7N of force to bend it to 90 degrees, so it ranks among the top 3% of the most flexible shoes we've ever analyzed in the lab.

Difference in stiffness in cold

Under cold temperatures, the flexibility follows a similar pattern to the softness. The change is clearly noticeable.

Needing 21.9N of force to bend it to 90 degrees, it doesn't retain its super-flexible characteristic anymore.

This results in a 59.5% increase, which disappointingly underperforms compared to most other shoes.

Size and fit

Internal length

At 272.9 mm, the shoe it's a little bit longer than it should (270 mm), but likely not enough to warrant sizing down unless your feet are particularly narrow.

Toebox width at the widest part

With a measurement of 100.4 mm, the Racer TR21 crosses the 100 mm threshold. This makes it, without a doubt, a wide shoe in the shelves.

Tongue: gusset type

While we don't usually anticipate a gusseted tongue in a $75 shoe, it feels like a fantastic bonus when we do encounter one. Unfortunately, we're out of luck this time.

Comfort

Tongue padding

For a shoe tipping the scales at over 11 ounces, it's seriously disappointing to find just a 2.9-mm-thick tongue. This could lead to compromised comfort, a letdown considering this is a casual shoe intended for all-day wear.

Heel tab

We're always fans of heel tabs, serving as both style-enhancers and practical aids for sliding your feet into the shoe.

This model features a finger-loop heel tab, which earns our praise—it's a cool-looking detail!

Removable insole

The insole isn't glued down. This means you have the flexibility to swap it out with custom orthotics or an insole from another shoe.
