WHEN TO WEAR SKYCHASER
Made for those who need a shoe that transitions from city streets to outdoor scrambles, the Skychaser AX5 MID GTX CLIMA delivers stability and comfort — with GORE-TEX protection to keep you dry and CLIMAWARM+ insulation for the coldest days.
CHOOSING THE RIGHT FIT
When choosing hiking shoes, aim for a fit that is snug all over, without being tight, and allows you to wiggle your toes. If shoes are too tight, they can be uncomfortable and cause blisters. Shoes that are too loose might cause your feet to slip, resulting in chafing. The Skychaser AX5 features Lightmotion lightweight cushioning for all day comfort that connects you directly to the terrain with superb responsiveness.
CLEANING GORE-TEX SHOES
Carefully wipe away any dirt with a soft cloth and lukewarm water, but no detergent. If you want to remove dirt from inside your GORE-TEX footwear, you can use lukewarm water and a small amount of liquid detergent.
Waterproof, insulated hiking boots made with CLIMAWARM+, our best thermal insulation.
Made for cold, damp weather, the adidas Terrex Skychaser AX5 Mid GORE-TEX CLIMAWARM+ hiking shoes are your ticket to winter adventure. A GORE-TEX membrane seals out wet conditions while letting your feet breathe for dry, comfortable feet in wet conditions, CLIMAWARM+ traps heat and releases sweat for a warm, dry and focused performance. A mid-height cuff provides extra support for your ankles across uneven terrain, and a Continental™ Rubber outsole provides secure footing, wet or dry.
CLIMAWARM+ advanced insulation provides superior engineering with advanced materials that unite for warm, dry and focused performance. Insulating materials trap warmth for optimal body temperature.

Sizes! I started with the gore tex trail maker in 8.5 my usual fit and was spot on for size , but decided to change for sky chaser Ax5
I needed a 9 in these as it was a tighter fit,
Not content in the end I opted for the Ax5 clima warm as I wanted the extra warmth, but I actually needed a 9.5 in these because of the extra padding used for warmth
So there is Upto a size difference between these particular 3 models!
Now the size and fit is perfect, waterproof and warm, very warm to be fair and so far my feet have been bone dry even after stood around in torrential rain a d walking through puddles and muddy fields . Comfy to wear and nice and light to wear . Definitely size up if you go clima warm .

go half a size up
Quality of the boots is fine. Go half a size up. for some reason this boots feels super tight and hurts the feet until u break the boot in. I'm a size 8 and it felt like I was wearing a 6 until the boot loosens off.
