I work in a warehouse with temp's varying from 45 to -40, my toes get very cold in the freezers wearing steel toed boots. I put these on high and wasn't impressed at first but about 45 minutes later they warmed up very nice. If used on the high setting my feet are super warm all night, problem is the batteries don't last long so you'll need to have extras. The medium and low settings don't really seem to do much of anything

I bought these things as a late night impulse purchase. Not going to lie....kind of pricey just to keep the feet warm. My husband grumbling the whole time about it as I reminded him my blood flow is horrible to my toes. He let it go eventually, and I'm thankful he did.

WELL, I decided to pop them on just before an early morning horseback ride at only 17 degrees with the wind blowing around 35mph. The only smart decision i made as i left in jeans, a columbia jacket, baseball hat, and a scarf. Everyone else showed up in coveralls and winter coats. I noticed immediately after we took off on our horses around 3am that the wind was biting cold. I mean within minutes every part of my body was numb. I lost feeling in my cheeks, lips and ears, and had to wrap my scarf several times around my head quickly. I knew the next two hours was going to be rough. Ten minutes in, my hips and butt were frozen to the saddle and aching so bad from the chill---to the bone pain. An hour in, I became quite dizzy from the chill and felt like going to sleep or falling from the horse. At this point I stopped talking to others as I feared they would catch on to my demise and make me turn around or call an ambulance. After laughing at me some I imagine. I was one of the youngest of the group and clearly the least prepared (except for my socks and scarf) so I stubbornly refused to quit. I made the ride, but by the time we got off our horses I couldn't feel my backside, hips, thighs, arms, hands, and face. The only reason my hands didn't have frostbite is because I intermittently would have to stick them against the skin off my bare chest. Talk about cold touch. For five hours after I sat trying to warm up after, involuntarily shivering in the heat as the cold drew away from my bones. The people in the group asked if I was going to be ok. I pondered my life choices for a while. I thought about how cold I was and what parts of my body weren't hurting so horribly bad as they warmed up. I pondered the parts that didnt ache and it was then I realized that just my toes and feet were HOT. Like really, really warm. I hadn't even thought about them the entire way. Usually, my toes are the first thing to hurt. It was just so miserable that i hadnt realized how good my feet were really feeling. There was one part of me that could keep going for hours more--- My feet! I believe to this day the heat generated from those socks kept me awake and going for the ride instead of slumped over my horse as my friends would've likely called for help after taking a picture of my dumb self. So thank you, socks. It's not our little secret anymore but it's real as it comes.

On a side note, if you want your socks to last for longer then put them in a lower setting. On high these bad boys lasted just over two hours but I'm thankful they did. Saved my hide that day. Also, if you're wondering....yes, I learned my lesson.

I have been using these for awhile and I will say they do keep my feet warm in the deer stand but the only issue I have and warn everyone is get a size up so they are not so difficult to put on and have learned if you put a sock outside of them they hold in a lot more heat. Overall if they last more than one season they will have been a good purchase if not then they will be an ok purchase.

For anyone wondering like I was the batteries do die within 3 hours on high but the plus side is they also charge quickly.

These socks are almost a life saver. I am a female in my late 60s. I suffered frostbite years ago. I lived in a warm climate for over 30 years but have moved to a four seasons climate about 4 years ago. These socks are the only reason I am not stuck inside during the winter months. The batteries last about 8 to 10 hours at a medium setting. I am able to comfortably walk 2 to 3 miles every morning and evening, without the pain and burning sensation I usually get. I do change them for wool socks if I am goin to be in the house most of the day and put them back on before heading out again, for a walk or any reason. I'm no longer "afraid" to be outside during the winter.
They stay up, at almost my knees, I don't feel the wires, my toes stay warm and the residual heat keeps my feet comfortable. They are durable also, I just retired my first pair, 4 years old. And the batteries are still working great so I have extra batteries. Husband likes them too, they make gifts or "prizes" so easy for him! For the record I have tries other heated socks. They didn't stay up, or as warm or last as long as these batteries do. I intend to walk 3 To 4 miles a day, as long as I can and these socks make it possible. THANKYOU Snowdeer. And the dog thanks you too!

These work perfectly as advertised, but I would not recommend them for skiing. The toes of the socks are much more bulky than regular socks, with an extra layer built in to protect the wires. If your ski boots are snug, then the toes of these socks are not going to fit comfortably inside. (The battery pack, by the way, up on your ankle, DOES fit with a ski boot - the sock reaches high enough on your calf that the battery does not interfere with your boot). I ended up cutting open the toe of the sock and removing the 2nd layer over the toe section! Now they work well, but they look a mess and will probably unravel over the winter. But my toes are warm & toasty!
