Heizteufels heatable "360° Warm Socks" heat 6 zones: the entire sole of the foot, the toes, the heel, the instep, the shin as well as the calf with 42°C feel-good temperature and very low power consumption. Thus, with a battery pack "Medi" at full heating power, a heating duration of 2.5 hours is achieved. With a battery pack "Medi-Push" or "Pro-Push" 3 heating levels are switched, 100% - 75% - 50%, thus extending the heating duration to almost 5 hours. The heatable 6-zone knee socks are made of an elastic mixed fabric and double-layered, which creates additional insulation against the cold from below. The knee socks have a comfort waistband that does not cut in and is reinforced at the heel and toe. A waterproof plug-in connection ensures safe outdoor use in cold and wet conditions. With the battery pack plugged together, noticeable warming is delivered immediately.
The knee socks are machine washable, if possible stow in a laundry bag and wash with wool or delicate cycle. Of course, hand washing is also possible. Please do not use fabric softener and tumble dryer!
The insoles get the necessary power supply with small but very powerful LiPo battery packs. For people with a normal feeling of cold, the "Medi-2" and "Medi-Push-2" heating packs are just right. If you are particularly sensitive to cold or are going to a very cold region, the "Pro-Push-2" heating pack is the right choice due to its twice as strong heating power. The Pro-Push battery is also recommended for outdoor workers, as the heating duration is sufficient for almost one working day. Sometimes it is advisable for leg and foot active persons like farmers, forestry or stable workers to carry the battery packs in the trouser pocket or a belt pouch - order the suitable connection cables 60cm, 90cm or 120cm then immediately.
Heizteufel offers various fastening and carrying options for each battery pack:
- Spring steel clip holder for boots, ankle boots and boots, can also be plugged into belt and waistband by means of connecting cable
- Velcro fastener for discreet, secure and snug attachment to the lower leg, preferably above the calf
- Textile clip pocket for belt and waistband as well as for boots and ankle boots
Frequent applications are:
- Working and standing on cold (foot) floors (in cold offices, at the market, in construction trailers, object protection, forestry and agriculture)
- Medical therapy and preventive care (for post-operative pain and low blood pressure, for wheelchair users).
- Sports (motorcycling and biking, fishing, horseback riding and paragliding, skating and skiing, mountain biking, hiking, outdoor sports events)

| Total current of all added heating consumers | = A | |||
| A-value x number of hours (planned heating time) | = Ah | |||
Ah = ampere-hour, the minimum capacity required of the battery at 100% heating power.
Example calculation for an 11.1V battery supply:
4-zone shirt + gloves = 4.3A x 2.5h (heating time in hours) = 10.75Ah.The battery capacity should be at least 10.75Ah for 2.5 heating hours.
Accordingly, the next largest battery technology would be a battery with 11.1V/12Ah.
