Your mileage may vary. I've only done long hikes (20+ km, multi-day) with full gear (30+ kg) in the army, and they worked well in those circumstances.
But then again, issues with feet were very common in those conditions, and for some, their sock/sizing really doesn't work.
If I was you, I wouldn't order them without first trying them on. The sizing is usually pretty generous (I wear 43 and 42, normal size for me 44), and getting a pair that is too big will fuck with your ankles/feet.
