Not 65c on high but warm-ish
Bought these for working in my unheated garage and skiing. Got them today, charged them fully and tried them out in my ski boots. On 65c the highest setting, they get warm, not hot and most certainly not 65c. But they will probably do okay for taking the edge off when its really cold out. If you suffer from cold feet in the winter and don't want to monkey with heated socks with wires and external batteries, these could work for you. I'm not going to say I am overly impressed because I'm sorry,. 65c should be really warm. A bit of embellishment on the advertising here. But again, there is a simplicity factor being wireless and freezing toes are no fun. I think compared to other very similar heated wireless insoles these are priced right. Thats why I'm giving them a middle of the road 3 stars rating. Any more expensive and there needs to be some wow factor. If they heated up to the advertised temp its 4 to 5 stars but sadly they do not. If they prematurely fail I will update this review accordingly.
Rating: 3 stars
