Purchased these just before this winter. I have now had the opportunity to use a number of times when hunting and have enjoyed them very much. They are not going to get hot, but do warm so that there is a noticible difference in how long I was able to stay on the stand in very cold temps due to feet getting cold. I even used inside my non-insulated boots when temps were just around freezing and they worked great for that too as I didn't have to wear the heavy boots and get sweaty feet walking in.
Warm Toes = More Stand Time
