I have those exact same heavy weights socks. 4 pairs.I have a fair amount of time on midweight Darn Tough boot socks and their ski socks with no issues. This is the only HWT pair I have (had). What’s funny is I got the heavier socks to swap once I get to my stand location to start each hunt with 100% dry feet. That sock tore like wet paper.
I’ve switched from 400 gram boots to much better 200 gram mtn boots and am looking for something Warmer than midweight but also durable.
Thought I’d try Buffalo. I’ve mid-weight alpaca socks already. I was interested in the these new Kodiak socks because of the higher Bison down content (65% overall). But it sounds like they’ll be too bulky.
Maybe I’ll just try grey wolf boot blankets or Arctic Shield.
