There is a sustainable AX4 variant, and it's called the Adidas Terrex AX4 Primegreen. It comes with an upper made with 50% recycled materials. Complete lab-specs overview 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). Adidas markets these shoes as offering a “lightweight trail running feel with the stability of a hiking shoe ”. We wanted them to feel as light as a feather, but unfortunately, they’re a touch heavier duty than anticipated. 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. This Adidas shoe also does not get as narrow towards the toes as most other hiking shoes do (it remains 15% wider to be exact).

More overlay coverage. The Adidas Terrex AX4 now comes with mudguards. Their presence delivers extra abrasion protection and more splash resistance.

Adidas’ entry-level hiker offers excellent grip, support, and durability for the price

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

Thanks to a tried and reliable Gore-Tex textile lining, these hiking shoes are waterproof. Although they only have a flood height of 3 inches, they keep water out of your shoes when crossing shallow creeks and muddy pathways. 3. Traction Like many footwear companies these days, Adidas is making a shift toward more sustainable production. The brand has pledged to replace virgin polyester with recycled polyester “wherever possible” by 2024—though that’s a fairly vague goal—and to make sure nine out of 10 of their articles contain a sustainable material by 2025. The brand is also experimenting with circular product design in a small line available only to members of their adiclub. What does this all mean for the Terrex AX4 here? Mainly that the upper features at least 50% recycled content. It’s not on par with competitors like Merrell’s Moab 3—which features 100% recycled laces, webbing, and mesh lining—but it’s a start, and we appreciate that.On a positive note, the shoe's toebox offers plenty of toe space as long as you have the right size length-wise. 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.

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. We discovered that the fourth iteration in the Terrex AX series comes with improvements over to its predecessor, the Terrex AX3. Here is what has changed: 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.You need only glance at particular models of hiking shoes to know it’s going to be a painful few months breaking them in, but that’s not the case with the Adidas Terrex AX4 GORE-TEX hiking shoes; they’re comfortable from the get-go.
