Autocastle 3.7V 2200mAh Rechargeable Battery Heated Socks for Men Women

These socks are phenomenal for the price. I've had them for two years now and while I don't wear them very often, they still work like new.As far as the functionality goes, the battery life is tremendous on low. Also. The battery doesn't seem to drain very much when not in use. When I first pull these out for the winter there has always been battery life after sitting for 8 months. The socks themselves are pretty thick and warm in their own right. There has been plenty of times where I didn't even need to turn them on. Because they are thick they are also quite comfortable. My wife has worn them around the house before on cold days and likes them a lot as well.The only cons I can see with these is that there is a little meter on the battery that shows whether it's in low, medium or high and that doesn't really work, you have to go by the intensity of the light. The battery also protrudes from the pouch in the top of the sock but I can never feel it... So neither are an issue for me and not worth docking even a fraction of a star.

Absolutely love these socks! My feet stay warm for hours. Also extremely comfortable and simple to use. Have used a few different types and these are the best out there!

Will work just fine to take off the edge, I currently use toe and foot warmers during my week in the woods hunting. Lots of waste and if not enough air flow, they don’t work. These stay warm till the batteries die. I’m having trouble getting a response from seller to order a second set of batteries. 5 stars for the socks. Batteries are small (about the size of your vehicle key fob). I tried the advice to wear the sock upside down (heel on top of your foot). This was a little uncomfortable, but kept the bottom of my foot toasty. Recommend you remove the socks before tracking and recovering an animal. Too hot and could damage the wires in the socks.

I bought these for stand hunting and it did absolutely nothing. It was record breaking cold weather at -15f this season in Minnesota and I was so happy I bought these until I was in my stand and turned one on and left the other one off. After 20 mins I could not tell you which sock I turned on ...zero difference in warmth. The heating element is on the top of the sock so it can't transfer heat and just heats up to 42C and does nothing. The battery on the site pushed on my calf super hard and hurt (i have big calfs) The socks however did keep my feet somewhat warm without the heating element on. The image on the left shows the sock and the heated element on the right is a 150 dollar insole I bought. The insole is so much better for conducting the heat to your foot because of the weight of your foot is on it. Also the remote is very nice to save battery life and convenience. Returning this as they were no effective. I actually only took the thermal image to see if they were working because I could not feel it.

Works well but because it heats only the top of your feet it isnt what i was lookin for, in the reviews it says it warms to the ankle so i thot it was toes to ankle heat but it wasn't. Still a good product. Wont buy them again tho.

My feet stayed warm on a 4 mile walk in 30 degrees weather. They were still working after 3 hours. My feet never got hot. My boots were about a half size larger than what I wear so my feet were completely comfortable the entire time. You need to try them on with different types of boots or shoes for your desired comfort.

I was hoping that these socks would be useful in keeping my feet warm this winter. Received them, charged the batteries and put them on. On first attempt the heating was completely inadequate, charged the batteries again (the red light on the battery came on automatically this time when I charged them) and after that there was noticeable heating occurring on high on the top of the foot. Not sure whether the heating will be adequate to keep my feet adequately warm through the cold weather months. The use of a ceramic heater at foot level may still be necessary (and cost is similar).

These are perfect for people who work outside or even just stay cold inside. The battery back does take some getting used to, but it's not too bulky. The socks get super warm. We've washed them and they come out just fine.
