High-quality materials are used in Adidas TERREX items to ensure you are ready for any weather. GORE-TEX®, for example, is both waterproof and breathable, making it excellent for long journeys. Polartec Alpha also performs well in terms of moisture control and breathability, ensuring that you keep warm without overheating. 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.

At 379 g or 13.4 oz per shoe, the Adidas Terrex AX4 is among the lightest trail shoes in circulation (FYI: in hiking, low-top shoes weighing 450g (15.9 oz) or less are considered light). 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. 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 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:The standard for pliability meets rigidity has been set. The AVA midsole adds support and stability through your foot so your foot still feels adequately encased without the fear of dodgy rolled ankles. 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 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. The unique mesh and synthetic materials of the TERREX shoe range contribute to a comfortable foot environment. Perspiration is routed away, to ensure a dry and comfortable shoe even after hours of jogging. Both adiPRENE® and TORSION® provide extra heel or midfoot stability, for traction on all types of surfaces. Even after many hours of exertion, the EVA midsole softly cushions every step. Final verdict

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. The lower price comes with some durability concerns, including lots of exposed stitching on the upper and a thinner, cheaper insole.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. On a positive note, the shoe's toebox offers plenty of toe space as long as you have the right size length-wise.

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

Great Shoes Whatever the Terrain

Even for running, whether on trails or on the road, we adored the pair. The shoe's sustainable sibling From the moment we put them on, the Adidas Terrex shoes felt stiffer compared to the other hiking shoes we tried. When worn on its own, the Swift's synthetic and cloth top is unyielding, and we discovered that the ankle collar gave the foot great support. 2. Withstanding submersion in water
