Heated Insoles These insoles are charged and placed in your shoes to protect your feet from the cold. Once charged, you can remove them from the cord and put them in your shoes, so your movement isn't restricted. The remote control is out of battery (I think) and hasn't been tested for operation. I was using them inside room shoes. I cut them to about 23.5cm. They can be made a few millimeters smaller. I haven't used them in outdoor shoes, so there's no dirt. They become gently warm. To reduce shipping costs, the price is set without the box (photo 6). If you want the box, it will be 1000 yen. Please let me know in the comments before purchasing. Please understand that this is a used item.
