What you're actually getting
The Terrex Skychaser AX5 sits in that sweet spot Adidas does well: not a chunky boot, not a flimsy trainer. It's a low-cut hiking shoe with Gore-TEX lining, which means actual waterproofing rather than the 'water resistant for about twenty minutes' stuff you get on cheaper pairs. The outsole is Continental rubber, same as you'd find on higher-end trail shoes. That matters on wet rock, which is basically half of Britain's countryside.
Personally, I've worn a previous Terrex model on a damp morning in the Peak District and the grip held up well enough that I stopped thinking about my feet, which is exactly what you want from a hiking shoe. You want them to disappear.
Who this is for, and who it isn't
If you do mixed terrain, day hikes, maybe the odd weekend trip somewhere muddy, these are spot on. Light enough that they're comfortable for longer distances. The Gore-TEX makes them genuinely versatile through autumn and winter too.
That said, if you're heading into serious mountains or carrying a heavy pack regularly, you'd want something with more ankle support and a stiffer sole. These aren't mountaineering boots. They're not trying to be.
The price question
The 863 degrees of community heat on HotUKDeals is a decent signal. That's not casual clicking, that's people who comparison-shop for a living flagging something properly good. Gore-TEX Adidas Terrex shoes regularly sit well above this price point, so if your current hikers are letting water in or the soles are separating (we've all been there), this is a reasonable moment to sort it out.
