The socks are available in pairs or in sets with batteries, the latter with 1.200 and 1.400 mAh capacity.

With 37% merino wool, the Therm-IC Powersocks feel very comfortable; the cable isn't a nuisance either. The material isn't quite as thick as some other heated socks, but the shaft is also quite high. The noticeable cable tunnel runs along the side of the foot and doesn't get in the way.
The batteries are connected with two snap fasteners and then held in place by two flat bands on the outside of the shaft - one with the snap fasteners and an elastic band that could be tighter. The rubberized battery consists of two parts with a flexible connection so that it can adapt to the shape of the leg.
The delivery includes a charger that consists of two separate charging trays. The batteries are inserted into these; internal metal tongues establish the electrical connection to the push buttons. There is also an app with which the three heating levels can be selected.
It can take a few minutes for the Therm-IC Powersocks to warm up; you can actually only feel the heating effect in the area of the big toes. Even at the highest level, the effect is not exactly overwhelming. It seems impossible to check the charge level.
