Definitely buy a half size up. They’re cosy - not sure how they’d fit with a thick sock on.

Great all-terrain boot.
This boot really stood up to task of going from really deep, wet, heavy mud to fast flowing streams and puddles. Kept my feet warm and dry throughout. Just not as comfortable as my Skychaser 2’s unfortunately, even with the ortholite insoles.

Great boot , looks good feels great
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 .
