Welcome to the Shanty Michael_M, Glad to have ya Aboard !
I don't know if this will help you, but it worked for us. I got the Missus a pair of the Arctic High insulated Muck boots and Smart wool socks and the silk sock liners. She doesn't put the muckboots on till we are at the lake, she used to put them on at the house and during the ride to the lake her feet would Perspire [she says women's feet don't sweat !
] and she always had cold feet because of it. Now she is good to go for the entire day, I still pack an extra pair of sock in the in the possibles bag just in case. Good luck !!
