Anyone use them to help keep your feet warm in our frigid winters?

Get a couple of pairs of thin poly sock liners to wear inside your wool socks, you'll love them.

I've got a couple pairs of polypropylene socks I sometimes wear under my thick winter socks. They probably help a little, but they're a pain if they slide down inside your boots.

These are what I have.

I've bought polypropylene socks and I just seem to go back to a pair of Filson heavyweight wool socks because after a long day out in the cold they aren't balled up around your toes in the bottom of your boots .
Yes they're expensive but buy once cry once and enjoy them for year's to come .

If you have the true sock liners on and do a lot of walking or if your feet sweat a lot, sock liners are great as they will wick away the moisture and keep you more comfortable.

I get the thin wool sock liners that are made in Sweden, Woolpower is the American division, not cheap but way better then polypro

And here I thought socks were boot liners.

That’s funny!!!

Cheap nylon dress socks, thinner the better, work great for me under heavy wool blend hunting socks. I like the ones that go up to about mid calf.

Good idea, used to but worn out, help lots. Dont have Walmart or farm supply store for years

Buy Drymax brand socks. No need for liners and you will never get a blister.
