These heated socks were the most comfortable pair we tested: I could barely feel the wires when I tried them on and neither could our testers. Not only was the fabric soft, but the socks had extra padding around the toes plus compression bands at the mid foot and ankle for a stay-in-place fit. When I first tried them, I was instantly impressed by how I couldn't feel the wires and how cozy the socks felt on their own. They heated up exactly where I needed it, however it wasn't clear how much battery was left. RELATED: The Best Heated Vests
