Have you ever tried mobile warming heated socks? When you hunt when it is below freezing, whether in a tree stand or a duck or ground blind, we all have experienced cold feet. It can ruin your day. I recently saw the Mobile Warming 3.7V Merino Socks at Costco and picked up a pair. I swear by merino as a hunting sock due to the scent control and the ability to keep your feet warm or cool if needed due to the moisture-wicking and insulation properties.
These socks have a USB rechargeable battery for each foot and the temperature is regulated by an application on your phone. You can push the button on the battery, Bluetooth connect your sock, and choose your heat level. They were easy to turn on in the field even with no cellular signal. My feet were comfortable at both low and medium temperatures for several hours while still having remaining charge. I also wore these socks without turning on the battery and felt that they were warm alone whereas I typically will wear two pairs of socks.
