This was our second purchase of a pair of electric sock liners for my wife. She has developed circulation problems with her feet and her hands. The electric sock liners have done an excellent job in warming her feet. In addition, I purchased electric glove liners which we had to exchange due to a finger sizing issue. The Warming Store made the electric glove liner exchange in a timely manner and honored the sales price in effect at the time of my original purchase. The electric glove lines have also done an excellent job in warming her hands, so much so, that she doesn't have to wear the glove liners at all times. I rate my personal business and product experience with the Warming Store as excellent.

I bought these to keep my toes from becoming uncomfortable on long winter rides. They serve this purpose well. I have not used the socks for more than 5 hours on any given ride, so I cannot say exactly how long they will go (on low heat), but 7 hours seems possible. They are reasonably comfortable and the wires do not often make themselves felt. I bought the largest size for my size 10.5 feet and wear them over thin regular socks. I am glad I made this purchase.

Love my liners, The height is long enough so the power button is above my boots which is extremely convenient. And the 3 heat setting is clutch for the different tolerances of weather.

These socks are the warmest I have had- love that the top, bottom my feet and toes are completely warmed. The second setting has lasted 7 hours in 20 degree weather. However, the wires are perfectly positioned over the ankle bone and really hurt a lot when I wear them with ski boots. I actually have bruises. They are fine in my snow shoe boots which are soft. Also this is the first pair of warmed socks that I can not put in the washing machine. Don't know why they give you a washing bag. Unlike the prior Gerbig socks, the calf elastic fits- the last ones I had to cut the elastic to fit over my calf- at 5' 4" and 118 pounds- my calves aren't large, but they corrected that and these socks are fine!!

Top notch items (Gerber 7V Vest and socks) at good price and quick shipping.

I highly recommend these liners. They warm your entire foot. I am a downhiller skier who suffers from Raynaud Syndrome and Chilblains. These socks have eliminated my symptoms and have allowed me to enjoy outdoor sports again. The only reason that I am rating 4 instead of 5 is because I have not been able to purchase back up batteries (sold out) and need them so I can ski longer than 4-5 hours at medium heat.

These liners are relatively easy to put on. They seem to run true-to-size. Hubby wears size 11 shoe. We bought him L/XL. I only wear womens 9.5 shoe, but didn’t want socks to be too small, so i ordered same L/xl. I have about a half inch of sock left at the heel when I put them on, so cloud have ordered smaller size. I compensate by wearing my liners over, rather than under another pair of socks. It works great. I get 7.5 hours out of my batteries, when used on low power. I haven’t tested the other powers, really, so can’t judge length of time, but that brings me to my four-star rating, which would really be a 4.75 star, but I don’t have that choice…. The batteries are inserted in a pocket at the top of the sock. We have been wearying them so that the battery is on the outside of our legs, thinking that they might hit as we walk, but we are somehow bumping the batteries and changing the heat setting. It only requires a light push to change the setting, which is nice for gloved hands, but we are working on varied construction projects, and find we suddenly have one foot hotter than the other. So, we will try wearing them with the batteries on the inside of our legs. It’s not a big deal, since it is obvious when the socks go from warm to warmer, you can just change it back. We work when the temps are in the upper 20’s, but not colder. I suppose we might have to turn up the socks, if it was colder out, but all we were trying to do is make sure our toes didn’t fall off in our boots by the end of a long day, outside. The rest of our body doesn’t want to work when it’s any colder. We have thick insoles in our boots, so we don’t notice the wires in the socks. While still at home, when we walk on the floor, we can feel the wires, but they are not uncomfortable, they are just noticeable. It’s perfectly acceptable. Additional batteries are too expensive for our tastes, so we don’t have any back-ups.
