Even in 20 to 30 degree weather for last 2 years my toes are cold. Never had a problem with this. usually my fingers. I have tried smart wool and about ever sock they have at cabelas . Those toe warmers drive me crazy in my boot. I am at the point to even spend 200 bucks on pair of heated shocks. I have been wearing same brand of boots for the last six years. I even have some of those wicked thick ones we use to wear 20 years ago. I think I have atleast 1/2 of 45 gallon garbage can liner bag full of socks that don't keep my toes warm.
