They can work, just depends on the person. I've bp hunted and hauled big loads in Inov-8's, Altra, and Hoka. As long as you know your body and your feet the weight savings and quick drying can be worth it. I've used them into Novembrer with a toe warmer insert and had warmer feet than partners in their stiff insulated boots. There are times where I've also missed the physical protection of a full leather boot in boulder fields and do also use a heavier Crispi at times. Every gear choice is a compromise to some extent.
They're great if you have hot feet. They're a great way to see what frostbite feels like if not. I have very cold feet so it's a no go, but I'll wear them right up until snow
That has been my experience with trail runners when going off-trail here in SW Montana as well. The thorns find their way through the lightweight construction and even through the thinner soles. And it only takes one thorn breaking through to bring my progress to an immediate stop.
I'll go in for many days but never further than 3/4 day in from the truck. That works out to about 1 day out with meat.
I learned to try to pair up with someone in about the same physical shape as you are or one that moves slow and deliberate when hunting and not in such a hurry to get there. If hunting partners lose patience with each other, hunting is no longer fun.
You can always pack a military grade poncho. These make great lean-to's, are light and durable, and have numerous uses.
