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.
Use the white needle, which you can click on the plug at the end of the cable.
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.
