kurtka adidas own the runcamo jacket meska zielono pomaranczowa | Our verdict

The adidas Crazy Shadow 2 sneakers stands out as a versatile option for beginners and casual runners. Its design boasts a highly breathable and top-notch upper, paired with a thin-and-plush midsole, effortlessly transitioning between a running shoe and a trendy sneaker. Despite these positives, we noted the lack of cushioning and a bit of extra weight make it a favorable option mainly for those aiming for shorter, occasional runs.

Who should NOT buy

Advanced runners may want to explore other alternatives, as we concluded that the Pureboost 23 falls short in terms of cushioning and responsiveness. Several superior options exist for daily running, including the adidas x IVY PARK Plus Leggings corti rosa acceso con monogramma, Saucony Triumph 21, and adidas nmd xr1 glitch collegiate blue black white for sale.

Additionally, the Pureboost 23 has a substantial heel-to-toe drop, making it a bad choice for forefoot strikers. We are convinced that those who favor this running style will do better in shoes with a smaller drop, such as the Saucony Kinvara 14 or the product eng 1024788 adidas Originals Hoodie.

Breathability

One of the first features to catch our eye about the Pureboost 23 is its upper, generously filled with ventilation holes. This design, in theory, promises superb breathability. However, at CerbeShops, we believe in rigorous testing and concrete proof rather than speculation.

Utilizing our specialized smoke-pumping machine, we evaluated the shoe's breathability in our lab and determined that it deserved a perfect score—5 out of 5.

What makes this achievement remarkable is the shoe's comfort. To counterbalance the potential for heat-related issues, the designers strategically incorporated large ventilation holes, ensuring a cool and airy experience.

To examine the ventilation holes closely, we placed the shoe under our microscope.

The upper reveals two distinct layers—a white exterior layer with holes every few millimeters, and a well-ventilated yellow layer providing structure.

This results in a winning blend of a cushioned, comfortable, and airy upper, one of the best we've ever tested in a daily running shoe.

Shoes that are well-ventilated and achieve this status through large holes often result in less-than-stellar durability, as we experienced with the Adidas Ultraboost 1.0.

Outsole hardness

Regrettably, this shoe lacks Continental rubber, often associated with top-notch durability and grip.

Nonetheless, the outsole holds its own in terms of grip, and we're eager to assess its performance in the durability sector.

Adidas incorporated several cutouts in key areas of the outsole to reduce weight.

First up is the hardness test, registering a below-average 75.1 HC. Could this result in less-than-ideal durability?

Outsole durability

A softer-than-average rubber might suggest compromised durability.

We used the Dremel again, this time in the outsole, as is our standard practice for all running shoes. We observed a 0.9-mm indentation, which, while being an average score, is quite favorable for such a soft, grip-enhancing rubber.

Cushioning

Heel stack

We discovered a heel stack height of 27.6 mm, which appears adequate for short to medium-distance runs. However, it evidently falls short in providing sufficient cushioning for long runs or for individuals with a heavier build.

The forefoot prompted us to double-check our measurement—it seemed unreal. With a mere 16.1 mm of cushioning, this ranks among the least cushioned shoes we've tested in the lab.

As a result, we find it hard to endorse this shoe for serious runners who strike the ground with their forefoot. We think that Adidas opted for less foam due to the shoe's overall weight constraints.

Drop

Adidas promotes the Pureboost 23 as having a 10-mm heel-to-toe drop. Yet, our detailed measurements reveal a different fact—we find an 11.5-mm difference between the heel and the forefoot.

This finding further supports the idea that the shoe is primarily designed for heel strikers.

Insole thickness

Midsole softness

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

Moving to the Boost midsole, we discovered its remarkable softness, registering at just 13.5 HA.

Even though Boost technology, a decade old, has transitioned from running shoes to sneakers, it continues to provide a comfortable and enjoyable ride!

After chilling the shoe in the freezer for 20 minutes and testing it again, we observed a consistent measurement of just 15.8 HA. This consistency verifies that the Pureboost 23 maintains its softness even in colder conditions.

Stability

The Pureboost 23 incorporates two TPU lateral pieces from the Ultraboost design to enhance stability in the heel. When paired with the low stack height and wide platform, this feature elevates the shoe's stability beyond that of many other neutral running shoes.

Torsional rigidity

The low stack height also makes this shoe exceptionally flexible (1/5), contributing positively to everyday comfort.

Indeed, the Pureboost 23 is an versatile choice for individuals seeking a pair suitable for casual runs, gym workouts, and everyday wear.

Midsole width in the forefoot

During our test runs, the shoe felt notably broad and stable with each landing, including while taking corners.

Upon inspecting the actual dimensions, we indeed discovered a generous width, measuring 115.0 mm at the broadest part of the forefoot.

Upon twisting the shoe, we immediately noticed its extreme flexibility, making us eager to conduct our signature 90-degree bend test on the Pureboost 23, expecting a notably low score.
