Heating element for knee-length socks from 30seven®

The socks feature a slit at the bottom of the toes, in which one holds the heating element with the white side up.

The cable is threaded upwards in the cable duct along the leg, after which the plug is connected to the battery, which is secured around the leg with a strap.
