I purchased these socks to use on my family’s annual 10-day hunting trip. I have feet that are almost always chilly, if not downright cold, and waiting for elk at 6 AM at 10,000 ft elevation usually makes the sun popping over the mountains somewhat of a religious experience. In the past I have been so miserable that I can hardly focus on anything but the ice blocks filling my boots. These socks changed hunting season forever. For the first time in my life, my feet were comfortably warm.Pros/Observations:1) The batteries do not interfere with movement. You do not even know they are there. I was able to hike, ride my horse, and sit in various positions without being bothered a bit. The batteries stayed perfectly in place, never grew warm, and were not cumbersome in any way.2) The socks are comfortable without being too thick. Some reviewers complained about the soles being thick. I did not find this to be the case at all. They feel like any other pair of high-quality wool socks I’ve ever worn. They fit nicely inside my boots, did not cause rubbing, and did not feel any different from a normal sock.3) The heat they produce is surprisingly natural. It doesn’t feel like you’re wearing a heated sock–it just feels like your feet are staying warm. There were no hot points or cold points. You can leave the socks on a low setting (3 was perfect for me) and enjoy sustained, natural-feeling heat. There’s no nonsense like with other products where you turn the heat on, get too hot, then turn it off, then repeat when you get cold again.4) The app is extremely simple and effective, with a clear battery read-out so you know how much juice is left. Linking the batteries to the app is very simple if the instructions are followed.5) The batteries can remain in “standby mode” for an entire day and retain 100% power.6) The batteries lasted on power levels 3-7 for 16+ hours on average.Cons/Observations:1) These socks are definitely best suited to all-day cold. The only issue I ran into (which isn’t a defect in the socks at all) is that they were great for the mornings but brutally warm in the afternoons (turned off, of course). But, such is hunting in Colorado in September (10 degrees at 4 AM, 75 degrees at 4 PM). If you intend to use them when it’s cold part of the day and warm the other part, I recommend packing a lighter pair of socks. One plus, though, is that they are wool, which means that even if your feet get sweaty you don’t feel like you’re walking in a puddle. You just feel hot.2) You cannot turn off the batteries, only put them in standby mode which automatically shuts off after 10 minutes (sometimes). The first night I had the batteries, they remained flashing in standby mode for more than 24 hours. The batteries stayed at 100% so it doesn’t really matter, but it annoyed me that I couldn’t just turn them off. I expect this feature exists so you can’t accidentally turn them off during activities.3) It really is ridiculous to drop $300 on a pair of socks then have to pay $5 for the app. You don’t HAVE to have the app, but it is a great tool for specific heat control and battery monitoring.Sizing: I am a female, 5’8, 170 lbs, shoe size 9 women’s, 7.5-8 men’s. I ordered the medium socks and they were perfect for me, if just the tiniest touch on the large side. I found them to be just a little tight on my calves with the band folded over to the conceal the battery, but not uncomfortably so.The bottom line:I would definitely purchase these socks again. The natural quality of the heat still boggles my mind but impresses me enormously. These socks alone changed hunting from a grueling endeavor to an enjoyable sport.

I bought these socks for hunting. I have chronically cold feet in the winter. After sitting immobile in ground/ tree blinds for several hours a day for the past 2 weeks with cold feet, I decided to buy some warm feet. These socks provide comfortable warmth (not heat) from heel to toe for several hours a day. Just what I need. While I have not been back out hunting yet, I have worn them regularly indoors and out in 6-30F temps for the last few days. My feet were always comfortably warm. I have yet to exceed a heat setting of 2, so I know I’ll have plenty of extra heat available if I need it during a long sit outside. I couldn’t ask for more.Having said that, after paying $300 for the socks, the $5 charge for the full control app is a ripoff! You can forego any remote control and just push the buttons on the battery packs, but that’s pretty hard to do when you’re wearing layers of clothing for cold weather activities. Don’t even bother with the free app. You get what you pay for and it’s worthless. The free basic app gives you 3 heat settings and will put the batteries in standby mode, but will not turn them off. Supposedly they turn off after 12 hours, but I had one unit stay on for 24 hours. The paid app gives you immediate 0-10 heat settings and immediate on/off. Who wouldn’t want maximum, on demand, control of all settings on an expensive pair of socks? Paying extra for the “privilege” is cheesy and sleazy!As to performance, I first wore these socks without another sock. You can feel the wires in the soles. I didn’t find this bothersome, but most of my activity is a short walk to a blind and then several hours of sitting still. A small price to pay for warm feet. I don’t know how they would feel if I wasskiing or hiking long distances. They also had a tendency to slip down into my boot and bunch up under my foot. I bought a pair of Incrediwear ski socks and wore them underneath these socks. The total thickness is about the same as a thick pair of wool socks (that don’t keep my feet warm). Not only does this combination provide incredibly even warmth without sweating, it also minimized the slippage and the feel of the wires.I gave this product 3 stars. For performance it deserves 4-4 1/2. My rating is a protest for gigging me $5 for the maximum control app.

The right foot sock overheated and burnt my foot. I had to disconnect the battery while skiing to stop it.

I bought these as a Christmas present for my husband. He has poor circulation in his feet. He absolutely loves these socks. They are definitely worth the money. They stayed warm all day on low heat. He said they fit like a thick pair of socks.

I usually have cold feet while skiing, these socks have made a difference. I can ski longer. Seems like towards the end of the day, feet start sweating and the feet get cold. The battery set on low has lasted all day in temps around 20 with windchill around.5.. Haven’t tried.to set battery at higher yet. Directions say if boot or feet wet socks won’t work.

Product is garbage. One sock quit working a month after I purchased them and now the second has quit working another month later. Don’t waist your time or money

I bought these for a hunt in Saskatchewan. I was there November 2018. There were a few days well below 0 fahrenheit. I sat on average 11 hours a day. I put the socks on low each morning. And my feet were comfortable all day. They didn’t get warm, but they also didn’t get cold. Just what I was hoping for. Worked great for me. No problems with batteries and they lasted all day.

For the first time in my life my toes were toasty warm the entire time I was skiing. I’ve been living with Raynaud’s for 37 years and even moved to Hawaii due to my circulation. This amazing product makes it possible to live and THRIVE in the cold.

For $300 these feel really cheap! they work pretty good, but aren’t super comfortable with the heating elements on the bottom. My feet are always cold when I ski so it was worth it to me to spend the money just to get the relief, but I wouldn’t recommend these until you’ve tried everything else you can to stay warm. If they were like 150 or so I’d say go for it but they are very pricey.

Gets maybe 80 degrees

I really wanted to like this item. Really tried to convince myself that my feet were nice and warm. Just wasn’t happening. Battery on high are good for 3 hours.Just couldn’t find the $350 value on these socks. Most likely worth $100. Coming to think about it, I shouldn’t have been trying to like. I should have been amazed by the comfort and warmth for $350.

5 stars because they WORK! Here are a few things to make note:1. To make the battery last as long as possible, set it on a lower setting. Then use the interval setting where it will switch on and off for the times you set. I like to set mine to come on for 10 minutes on level 2 or 3, then off for 20 minutes. This does not drain the batteries so fast and helps them last much longer.2. These are really helpful for people who have Raynauds. When your feet are intolerant to cold, you can feel these heat up right away. They are so helpful in relieving symptoms immediately and reducing the pain from restricted blood flow and then coming back which is painful.3. The batteries are a bit bulky, and tough to wear with skinny jeans. I try to wear them over my jeans and under my boots, tucking them inside the boots. You just need to turn the lights off on the batteries. When wearing with boots, I add another layer of socks over the top of the warming socks to trap in the warmth. It helps.4. The phone app has settings that go from 0-10 for the levels of heat you want. The sock warms not just your toes, but all the way around the base of your foot. It has the interval settings on the phone app, and is very simple to use.5. The batteries do not take very long to charge, and could easily recharge over a few hour period. The socks apparently could be washed, although I have not opted to wash them yet. They still work great!If you have perpetually cold feet, these are the foot warmers to make a difference!

Socks were warm enough only on high. Fully charged batteries only lasted 3 hours. Because they only heat the the toes, I could still sense cold coming through the bottom of my boots when out for a walk. (I guess I need to look for fully heated insoles instead?) When I tried to recharge batteries overnight and into the next day, I never got a green light indicating full charge.

I love these socks! My toes have always been frozen on ski days… but with these socks they stay nice and toasty.My complaint is with battery life. The literature seems to imply that it should be easy to cover a full day of skiing, but I have to work like crazy to keep the heat on for a full ski day (6 hours).What seems to work for me is in the phone app to use a heat setting of 3 out of 10; and then do an interval setting of 3min on/ 1min off. That seems to keep my toes warm and stretches the batteries so they don’t die until near the end of the day.

I have NORMAL woman legs and once you turn the tops on these to cover the batteriesthe cuff at the top of my calf hurt so much my feet went numb! (I’m only 5’4″ 120lbsaverage size woman & legs! OMG. I tried I did to enjoy them. My feet were never HOT,but instead these just kept them at room temp which was okay….enough…sigh. Set upis very confusing manual is poorly written. Also the battery constantly flashes no wayto turn off/not draining but no way to turn off. Since worn 2x I can’t return so am sellingnow on another website that rhymes with e-stay. 🙂 Customer service said they sell thesethrough over 100 retailers and they do make a slim version but mine were not slim.Wow, what do the heavy people wear???? Shame. The low heat and calf pain were justnot worth the money / no.
