It's great to have warm feet by using the heated insoles. It can be a lot of work taking out the existing insoles in a pair of shoes so the heated insoles can be used. I want to use them in a number of different boots and shoes. I wish there were a better way.

These are a great idea for shoes that you will always need the heat in. I was originally looking for electric socks, but was concerned about the comfort of the battery pack further up the ankle or calf while wearing them with tall fire boots. Socks would be more versatile, and could could serve in any shoe, but the soles appeared to fit my needs specifically. The remote worked remarkably well, but getting positive feedback from the insole when turned on or off was less practical. The indicator light is at the back of the heel and is difficult to see when the insole is fully seated in the boot. I have settled on having it almost fully in place and sticking the fabric flap out of the way so I can more easily see the power light.

Great idea but I am disappointed. I purchased these insoles to use with my running shoes during the winter, when my toes freeze to the point of numbness. User-wise, what I find most frustrating is that there is no feedback on the remote control that reflects the current setting on the insoles. This includes any indication that the heating mechanism has been turned off. Since I wear them nearly daily for about an hour at a time, I'd rather not have to dig them out of my shoes after every run to make sure they're off. I've also found that I really have to fiddle to attach the charging port to one of the insoles. I'm concerned that it is just a matter of time before I won't be able to connect it at all. Lastly, they don't keep my toes warm. I tried wearing them with one turned on and the other off. Probably has something to do with my Raynaud's condition, but I could not distinguish the difference during wear. (I could feel by hand touch that it was actually working.) I purchased these as in "Open Box" product, with the understanding that they are not returnable. Thank you for welcoming feedback. I will say that they are comfortable, and online support was helpful. They might be better suited for ski boots.

These are great, they have become part of my everyday routine. Only wish there was some indication they are on or off, as it is hard to tell once they are in your shoes.
