- Element positions itself along your lower leg, wrapping around the Achilles and under the arches and delivering heat to your toes and balls of feet
- Simply pull socks on, align upper cuff with BootDoc (BD) logo in front, position the heating element beneath toes and balls of feet, and then connect charged battery pack
