The thinnest possible heated sole with maximum heating surface? That's what this BERTSCHAT® Ultra Power heated insole is all about! With this Dual Heating version, you have twice as many heating zones compared to other insoles. Thanks to this new technological development, the entire sole is heated. Being only 4 mm thick, it’s a sure fit in any type of shoe.

Unique heating area

The heating area covers the entire sole, thus truly heating the entire footbed. We recommend wearing well-insulated shoes, as this enhances the heating effect by conserving the generated warmth.

Always the perfect temperature

With the remote control, which is included, you can control the temperature in three different heat settings. You have a choice of three settings: low (1), medium (2) and high (3). Especially on the highest setting, in well insulated shoes, the temperature can reach unprecedented levels of warmth.

One size fits all

The sole can be cut to size. Located on the bottom of the soles are cutting lines, allowing for trimming from men’s size 13 all the way down to women’s size 3. Easy to install and remove, they are truly compatible with any type of shoe.

Battery and mechanism

Because the sole is so extremely thin - 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 four times more powerful than comparable models currently on offer.

The battery can be attached to your shoes by means of a clip. If you prefer to have the battery out of sight, that is possible with an extension cable. This allows you to easily carry the batteries in your trousers or jackets pocket. We offer the extension cables for a discounted price of €10,00 when selected through our combi-deals.

USB-Rechargeable

The included batteries are USB-rechargeable. This allows you to charge them on the go. On a single battery charge, you can heat for up to 16 hours. If you would you like to heat longer consecutively we offer an additional set of batteries separately .

Suitable for:

Because the soles are extremely thin and flat, they are suitable for all shoes. From sports shoes to hiking boots and cycling shoes to ski boots.
