Adidas Alphaboost V1 Buy

Who should NOT buy

No matter how appealing it is, the Adidas Alphaboost V1 will still turn off sneakerheads who do not like the thick midsoles of platform shoes. Some of us here felt that the extra platform just made the shoe bulkier.  The Adidas Superstar might be a better alternative.

We felt that the Adidas Alphaboost V1 was a pretty rigid shoe. Those who like the Alphaboost V1 but are just not so sure about its overall rigidity might want to try the PUMA RS-X. This Puma sneaker is still a platform shoe, only far more flexible.

Breathability

By looking at the Adidas Alphaboost V1, we already had the idea that it would be breathable. The upper material has a lot of ventilation holes.

True enough, we never felt hot while wearing this Adidas sneaker.

On a scale of 1 to 5 where 5 is the most breathable, we happily give this shoe a 4 during our smoke test. Our feet felt fresh for long periods and we never had to worry about wet smelly socks after our strolls.

We examined the upper material under the microscope. And we were happy with what the device showed us.

We saw that while the material is closely knit, it still has spaces in between the threads that allow easy passage of air.

We also performed a quick transparency test, and it showed that a good part of the upper allowed light to pass through, which we consider an indicator of how well-ventilated this shoe is.

Durability

Toebox durability

There are overlays on the upper, and they are there to enhance the shoe's durability. We subjected the overlaid parts to our standard Dremel drilling, and we were pretty satisfied with the results. 

The layered materials displayed a decent amount of resistance to abrasion. Ultimately, we gave the shoe a solid 3 out of 5 for the durability of its toebox.

Heel padding durability

The heel padding felt soft and pliable, that's why we were pleasantly surprised when it showed a lot of resistance during our Dremel test.

We took a photo of the immediate aftermath and the damage that the heel padding incurred is no more than just being disheveled. Hence, we give this part of the shoe a high score of 4 out of 5 for durability.

Outsole hardness

We used an HC durometer to measure the hardness of the outsole in the lab. The device gave a rating of 89.3, which makes the Adidas Alphaboost V1's sole slightly harder than average.

Given this figure, we are pretty confident that the sole is going to resist abrasion for a while. We'd been running and skipping in this shoe during our tests, and it surely did hold up quite well.

Outsole durability

The durability of the outsole is definitely one of this shoe's highlights. We performed another Dremel drilling session on it, and we were so pleased that our tool barely left a mark on it.

To be quite specific, our Dremel drill only left a dent that is 0.4 mm deep. This figure is far lower than the average. It's pretty safe to say that the Alphaboost V1 is a shoe built for outdoor excursions.

Outsole thickness

Our caliper showed that the outsole is thinner than average at 4.2 mm. However, we do not worry about this because of its durability.

Sneakers like the PUMA RS-X may have thicker soles (its sole is 6.5 mm thick!), but they might still bottom out sooner because they are only half as durable (the Dremel test resulted in 0.8 mm damage) as the Adidas Alphaboost V1.

Weight

Even if it offered a lot of durability and cushioning, the Adidas Alphaboost V1 still managed to be slightly lighter than average at 13.2 ounces or 373.0 grams. Walking in this shoe never felt like a chore because of its relatively light structure.

Cushioning

Heel stack

The shoe's huge midsole is easily one of its most prominent features. The heel area is 41.8 mm thick! This number adds 37% more thickness to the average!

Forefoot stack

Just like the heel, the forefoot also packs up on volume. At 28.3 mm thick, this part of the shoe dwarfs the average by as much as 32%.

The Adidas Alphaboost V1 is definitely the shoe that we will wear if we want to appear taller. It's even better than many of the platform sneakers out there.

Drop

Though the midsole is a lot thicker, the shoe's heel-to-toe drop remained to be just around the average. Because of this, we did not have issues with heel-to-toe transitions. We can even say that our steps were pretty smooth.

When we did the calculations in the lab, the drop was pegged at 13.5 mm. The Adidas Gazelle is still going to be a better pick for wearers who want more natural-feeling footwear.

Midsole softness

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

The midsole felt especially thic so we were worried that it was going to be firm. Thankfully, this was not the case.

The midsole never felt so soft that our feet just sank into it. It felt soft enough to provide comfort but still firm enough to ensure much-needed bounce.

Our HA durometer gave the midsole a rating of 22.4, making it only slightly but significantly softer than average.

Insole thickness

The insole is only 3.3 mm thick, and it's surely thinner than average. We did not worry about this because the midsole was already so thick, and it already did most of the job.

Stability

Lateral stability test

Many people shy away from platform shoes because of stability problems. Fortunately, we encountered no such issues while wearing the Alphaboost V1 from Adidas.

Because of its pretty twist-resistant base (we will get to this more shortly), we never felt wobbly even when our movements started to become a bit shiftier and more aggressive.

Torsional rigidity

Foot twists are painful and we wished to avoid them at all costs. Good thing the Adidas Alphaboost V1 was a reliable ally in this regard. It scored a perfect 5 for torsional rigidity after we gave it a good manual twist in the lab.

Heel counter stiffness

The heel counter surely felt durable, but it didn't have that much stiffness. It only got a 2 out of 5 in our manual stiffness test in the lab.

Fortunately, the heel's softness never came to a point where we felt our rearfoot to be not sufficiently supported. The less stiff heel counter just allowed more freedom of movement in that area, making it an ideal partner for long strolls around town.

Midsole width - forefoot

Another thing that made this shoe notably stable is its fairly wide platform. Our caliper measured the midsole to be 117.8 mm wide at the forefoot, and this number is significantly higher than average.

Midsole width - heel

The story at the heel is even grander. Our caliper measured this area to be 102.9 mm wide. This adds around 20 mm extra space to the average. Yes, you read that right. 20 mm! We've tested a lot of sneakers, and the Adidas Alphaboost V1 is easily among the widest!

With that much space for splays and even momentary shifts, our feet surely couldn't go anywhere else but remain within the footbed.

Flexibility

Stiffness

If there is one thing that we didn't enjoy as much, it would be this shoe's pretty rigid structure. While it ensured stability, it also made it difficult to do more natural foot flexions.

We conducted a flexibility test on the Alphaboost V1 and we saw that it needed a whopping 41.9N of force to bend at 90 degrees. This number if twice the average sneaker would need.

Grip / Traction

The outsole of the Adidas Alphaboost V1 features a unique pattern. Thankfully, it did not mess up with shoe's grip.

We enjoyed the traction that this shoe provided on a variety of surfaces. Concrete. Wood. Asphalt. Ceramic tiles. On whichever floor we walked on, we were able to stop when needed and the shoe's grip allowed us to walk strong and with confidence.

Size and fit

Toebox width - widest part

The widest part of the toebox is only 95.8 mm wide as per our caliper measurements. This number is just around the average, so our recommendation is for those who have normal-sized feet to go true to size. Those who have wider feet may want to size up.

Tongue: gusset type

The tongue is non-gusseted and we are thankful for it. We have already seen that the whole shoe is pretty rigid, so it would have been too constricting if the tongue still sported a gusseted design. 

The Alphaboost V1's not-so-stiff heel and non-gusseted tongue gave us the give that we needed to still move comfortably when the rest of the shoe was pretty inflexible.

Removable insole

Just like many other sneakers, the insole of the Adidas Alphaboost V1 is removable. It was easy to get rid of it when we needed to wear orthotics and other forms of shoe inserts.
