Bertschat Heated insoles Extra thin Dual Heating Ultra Power

The thinnest possible heating sole with maximum heating surface? That's what this BERTSCHAT Ultra Power heating sole has. With this dual heating version, you have twice as many heating zones compared to other insoles. This new technological development heats the entire sole. The sole is only 4 mm thin and therefore suitable for any shoe. The heating surface extends over the entire sole so that the entire sole is really heated. We recommend wearing well-insulated shoes, as this increases the heating effect. You can regulate the temperature in three different heat levels using the remote control supplied. You can choose from three modes: low (1), medium (2) and high (3). Especially at the highest level, in insulated shoes, the temperature can reach unimagined heights. The sole can be cut to size. On the back you will find the cutting lines from size 36 to 48 so that it fits in every shoe. You can simply remove the sole and put it in another shoe. Because the sole is so extremely thin at 4 millimetres, an external battery is included. This powerful battery has a capacity of 3,800 mAh at 7.4 volts. This makes the battery up to 4x more powerful than comparable models. The battery can be attached to your shoes using a clip. Do you prefer to have the battery out of sight? This is possible using an extension cable. This means you can easily stow the battery in your trouser or jacket pocket. The extension cable can easily be ordered in the order menu at a reduced price. The batteries supplied are rechargeable via USB. This way you can charge them on the go. You can heat for around 16 hours on a single charge. Would you like to heat for longer at a time? This is possible by purchasing an extra set of batteries.
