I've got the men's version of this boot and I would say it is absolutely fine for anything less than heavy (50+ lbs) load hauling. With a 30 lb pack, you'll be fine with this boot. I love them and even though I usually hike and backpack in trail runners, I use these for steep stuff when I have my toddler on my back because they do provide extra support and the brake heel is great on steep downhill walks.
