These rechargeable heated insoles are comfortable, versatile, and easy to use. They come in four sizes, and can be easily cut to size if they are too big - just make sure you cut around the sizing markings on the toe and don't cut the heel, where the battery is located!
The battery used in these insoles is rechargeable, and can be used for up to 4 hours, depending on the temperature setting. This time can be further increased by switching the insoles on for short bursts as needed. The charger plugs into the back of the heel, so there is no need to remove the battery in order to charge. The insoles come with a USB cable charger, ideal for charging via PC or laptops, or via wall adapter (not included).
Trim to Your Exact Shoe Size
The insoles can be trimmed to achieve a perfect fit. This makes them versatile, and means that they can fit into many different types of footwear. They are perfect for partaking in winter sports, such as skiing, or for anyone who works outdoors.
A handy storage bag is included so that you can keep the insoles together as a pair. If you are going on holiday or travelling then this bag will be incredibly useful.
