I run uninsulated boots year round. Crispis & Zamberlans. My feet sweat in insulated boots & freeze.

Just change your socks to match the temperature. light merino for early season/turkey season, heavy weight merino for normal 30-50 degree days, hollow socks when it gets 20s or below. Extreme cold, like -20s windchill in oklahoma last year, I put on the artic shields when I get in the stand.
