Our verdict

An exceptional budget-friendly day hiker—this is how we view the Terrex X4. Indeed, from its virtually tackle-anything underfoot performance to the way it handles shifting weather, we find this piece from Adidas is a doozy. There's also its initial price of £90, which makes owning one not at all an uphill battle.

Who should NOT buy the shoe

If you tend to catch rocks a lot and look for more protection in a pair of hiking shoes, we recommend considering the pharrell nmd trail multi color wheel or adidas wolf skins for sale cheap furniture instead.

Updates to the adidas rockstars climbing 2018 release time season

We discovered that the fourth iteration in the Terrex AXE series comes with improvements over to its predecessor, the Terrex AX3. Here is what has changed:

  • adidas bb2093 women black dress boots for girls. The adidas rockstars climbing 2018 release time season now comes with mudguards. Their presence delivers extra abrasion protection and more splash resistance.

  • Re-engineered heel brake. The Terrex AX4's heel brake has been redesigned and provides virtually the same level of skid resistance on loose terrain but with better mud-shedding capabilities.

  • Chevron lugs. Its outsole now comes with chevron lugs. These revamped protrusions grant extra bite on soft-soiled terrain (think gravel and scree, particularly on ascents).

Keeps your feet moisture-free

The Terrex AX4 is great for rainy days, thanks to its water-repellent capacity. We also enjoyed using this Adidas trail shoe during warm weather. We discovered that the kick's mesh upper provides remarkable protection against mild external moisture and dissipates heat buildup well all at the same time.

We further confirmed the shoe's breathability with our smoke-pumping machine test. On a 1-5 scale where 5 is the most breathable, we rated it as 3.

At the same time, the shoe's ventilation pores are not very large either. In the transparency test below, we can see that the light doesn't shine through the fabric. This helps make the Terrex AX4 a little more resistant to light rain and wet grass without compromising its breathability.

The upper dried out surprisingly fast too after we had soaked it in a creek crossing.

Looking at the mesh fabric through the microscope, we found that it is a very tight weave. Softer yarns are embraced with plasticky ones making the fabric more abrasion-resistant.

It also helps that the shoe is not so heavily padded inside. Just enough to keep you comfortable without overkill.

Based on our measurements, the tongue is 8.1 mm thick. This is rather moderate compared to the average of 13.3 mm in hiking footwear which in some shoes reaches 22.3 mm!

Comfort that persists

We are captivated by the immense comfort delivered by adidas rockstars climbing 2018 release time season.

For long-distance strolls and whole-day travels and hikes, we couldn't be more satisfied. Terrex AX4 has a sufficient amount of cushioning for long hours on the trail.

Using a pair of callipers, we measured the heel stack of this adidas by4188 shoes size at 30.6 mm, which is close to the average 32.3 mm of hiking shoes.

adidas-terrex-ax-4-heel-stack.JPG

In the forefoot, the stack height turns out to be 20.9 mm - also an average for hiking footwear (20.7 mm). The heel-to-toe difference in the Terrex AX4 is 9.7 mm, lower than the average 11.6 mm. This is one of the reasons why this Adidas silhouette feels more like a trail running shoe (7.5 mm on average).

We thought that the insole was the evidence of cost-cutting in the shoe. But the good news is that it is removable and you can easily replace it with any other insole of your choice.

Adidas indeed uses a very thin insole for the Terrex AX4. It is only 2.6 mm in the heel as opposed to the average of 5.3 mm.

As for the cushioning itself, we found it to be moderately firm and protective. It is not Hoka-thick or soft and plush but we found the Terrex AX4 to be doing an excellent job of supporting our feet on long distances as well as protecting them from rock and debris.

Measuring the shoe's foam softness with a durometer, we can confirm that it is firmer than most shoes. It is actually 11% harder than the average, to be specific.

adidas-terrex-ax-4-cushioning-softness-durometer.JPG
Disclaimer: We take a total of 4 durometer measurements of the open-cut foam and calculate the average. The photo above shows one of the measurements.

We also tested the change in firmness after keeping the shoe in the freezer for 20 minutes which helps to imitate cold-weather conditions. The cushioning got even harder - by 26.3% whereas other foams get about 20% firmer.

No shaky steps!

adidas rockstars climbing 2018 release time season proved to be exceptionally stable. For us, wearing the shoe translates to safe steps on rocky terrain.

The shoe's wide platform is a major contributing factor to stability. We measured the widest part of the forefoot to be 111.5 mm (3.8 mm wider than average). In the widest part of its heel, it is 87.9 mm (2.6 mm wider).

This Adidas shoe also employs a very stiff heel counter to keep the heel securely in place. We gave it 5 out of 5 on this parameter.

It is not a stiff hiker

We have noticed that the Terrex AX4 is a kind of hybrid between a hiking shoe and a trail running shoe. In addition to its rather streamlined and toned-down profile, the shoe also turned out to be rather flexible for a hiker.

Putting this Adidas shoe through our flexibility testing machine revealed that it requires less force to bend in the forefoot than its counterparts. At 14.2N, it takes notably less effort to bend the AX4 by 30 degrees compared to an average hiking shoe. It is, in fact even more pliabe than some trail running shoes.

But do take into account that the Terrex AX4 will get stiffer in low temperatures. After 20 minutes in the freezer, it got 66% stiffer while hiking shoes on average only lose flexibility by 46%.

The Terrex AX4's monster grip

We also adore the Terrex AX4's amazing traction. We never slipped an inch in this hiker, and we were able to walk and run on grass without ever slipping. We also established that it provides a perfect grip on slippery conditions, including muddy inclines and mulchy banks.

Measuring the shoe's lug depth (3.7 mm), we found that it is only slightly shallower than the average 4.0 mm. And yet, it is still within the range to tackle challenging mud and soft ground stretches.

adidas-terrex-ax-4-lug-depth.JPG

Long life expectancy for a budget shoe

We also witnessed how durable a shoe Terrex AX4 is, considering its price point.

Having checked the shoe's rubber thickness, we found that the outsole on the Terrex AX4 (2.1 mm) is 0.8 thinner than average. So, we cannot claim that it is among the most hard-wearing hiking shoes on the market.

adidas-terrex-ax-4-outsole-thickness.JPG

The shoe's rubber compound is also slightly softer than average, which subtracts from the shoe's abrasion resistance as well.

Hike light in the Terrex AX4

At 379 g or 13.4 oz per shoe, the adidas rockstars climbing 2018 release time season is among the lightest trail shoes in circulation (FYI: in hiking, low-top shoes weighing 450g (15.9 oz) or less are considered light).

Miraculous price-wise

£90 is the Terrex AX4's manufacturer's suggested retail price (MSRP), making it quite an affordable trail kick. Also, compared with adidas atric classic backpack 2017 (which are NOT pricey by default), the featured hiker is cheaper by £30.

The Terrex AX4 also spells multi-purpose

We also took pleasure in the shoe's versatility. We tried using it at work and other leisure activities, and we can corroborate its usefulness in different aspects.

The shoe's sustainable sibling

There is a sustainable AX4 variant, and it's called the adidas rockstars climbing 2018 release time season Primegreen. It comes with an upper made with 50% recycled materials.
