Product Information

Full details

The Adidas Terrex Skychaser Ax5 Gtx is a technical hiking shoe designed for adult men who need agility and protection on demanding mountain terrain. Featuring a waterproof GORE-TEX membrane and a responsive LIGHTMOTION EVA midsole, these trainers excel at keeping feet dry and comfortable during fast-paced hikes; however, users should note that the lightweight design prioritizes agility over the heavy-duty ankle support found in traditional high-cut hiking boots.

FAQs

Are these shoes suitable for running?

While they are built for agility, they are primarily designed as hiking trainers. They provide excellent support for hiking but may feel stiffer than dedicated trail running shoes.

Can I use these for winter hiking?

They are suitable for damp and cool conditions, but they are not insulated for sub-zero temperatures or deep snow.

How do I ensure the correct fit?

These shoes are designed for a regular fit. It is recommended to try them on in the afternoon when your feet are slightly swollen, as they would be during a hike.

What is the weight of the shoe?

Each shoe weighs approximately 440 grams, providing a lightweight feel for technical terrain.

Are the insoles removable?

Yes, the OrthoLite sockliners can be removed for cleaning or if you need to use custom orthotic inserts.

Troubleshooting

Foot feels too hot or sweaty

Ensure you are wearing technical, moisture-wicking synthetic or wool socks rather than cotton, which traps moisture.

Mud accumulation in outsole grooves

Use a stiff-bristled brush to clear the tread patterns after your hike to maintain consistent grip for the next outing.

Loss of water repellency over time

Apply a GORE-TEX safe DWR (Durable Water Repellent) spray to the exterior upper once it is clean and dry.

Pros and Cons

Pros

  • Excellent traction on wet and rocky terrain
  • Lightweight construction prevents fatigue
  • Effective waterproof protection
  • Good energy return from the EVA midsole

Cons

  • Lower ankle profile offers less stability than full boots
  • Not intended for extreme high-altitude alpine mountaineering
  • Limited to adult male fit specifications

Setup, Compatibility & Care

These trainers feature a standard lace-up closure that allows for a secure, customized fit. To ensure longevity, always loosen the laces fully before removing the shoes to prevent heel collapse. After hiking in muddy or dusty conditions, remove the OrthoLite sockliner and allow the shoes to air dry naturally away from direct heat sources, such as radiators, which can damage the GORE-TEX membrane. Clean the exterior with a soft brush and lukewarm water. Avoid machine washing, as the heat and agitation can degrade the structural adhesives and waterproof integrity.
