I wore a pair a few seasons back & after walking, my feet stayed warmer, but after sitting w/ slower blood circulation, same as usual socks. My go to is a boot 1/2 size bigger w/ 50 cent toe warmers on colder sits.
I’ve fished without any shelter in minus 26 degrees, and never had cold toes.If you need toe warmers, you need to find a better sock combination, and a better boot!
Those of us that are 60+ years old might disagree with that. Poor circulation...the struggle is real. And I wouldn't fish in -26* at any age. Shelter or not.
And you still haven't learned to come in when it's -26° outside ?!
…I guess not! 😬
