My feet always get cold come later in the season. I actually bit the bullet and got a pair of electric socks on Amazon. They easily last 3 hours, which is the longest I generally sit in late season. I will hold out as long as I can, then turn them on. Within minutes my feet are warm again. They have lasted about 6 hours longest, and my feet were good all that time. I am considering a second set of batteries for tgem, or a second pair. At $42, they weren't cheap. But, I have been comfortable ever since. Best $42 I have spent to be comfortable in a stand.
