Heated Insoles – Extra Thin – Ultra Power

A large heating surface, maximum battery capacity and the thinnest possible sole - that's what BERTSCHAT®s Ultra Power line offers. The advantage of this extremely flat sole (only 4 millimetres!) is that it fits any shoe, from sneakers and sportswear to the thickest of winter boot. These soles can also be used for various sports activities such as cycling and mountain biking.

Unique sole

The heating area covers the entire front part of the sole. We recommend wearing them in insulated shoes, as this significantly enhances the warmth by retaining heat. These soles are a true one size fits all since they can be trimmed from men’s size 13 all the way down to a women’s size 3.

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).

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 20 hours. If you would you like to heat longer consecutively we offer an additional set of batteries separately here.

Suitable for:

Because the soles are extremely flat, they are compatible with all shoes. From sports shoes to hiking boots, cycling shoes and even the sturdiest of ski boots.

Good to know:

Wearing heated soles and clothing indoors allows you to turn down the thermostat? You no longer need to heat the entire room. This to the benefit of your energy bill.
