I’ve got to suggest electric socks!
I’ve got two nice pairs of Rock boots (don’t know exactly what model)
The warmest ones keep my feet warm sitting all day,in the coldest weather.
But are miserably hot when exerting any energy, like walking, climbing, or dragging a deer.
I Find I’m a lot more comfortable in the lighter pair and plugging the battery on the electric socks while I’m sitting in the stand.
