My husband works outside in all seasons so I purchased these for him now that the weather has been turning cold. He had nothing but good things to say about them. They battery lasted his full work day (10 hrs). I was concerned with washing, but they are easy to wash (I put them in a laundry bag to be safe!). Will be purchasing another pair for him for Christmas.

Socks fire !! I will order 2 more pairs, in -20 with the dog I went for a walk in these socks and winter ankle boots, my feet were thrust into a snowdrift at maximum power, the heat is hot, on the average level it is quite comfortable

They heat up super fast! Would definitely fit a wide range of shoe sizes. They also fit good over my wide calves. All around a good product!!

Keep whole feet warm. I have tested them in offroad snow mountain biking (around -3, wet) and they worked for more than 6 hours set on the 2nd level perfectly and the battery was not depleted after the day.

I was greatly surprised at how much nicer the sock quality is. They are so soft and warm even without turning the batteries on. It hasn’t been extremely cold yet but on low, these socks give just the right amount of heat to keep my toes warm. I really like them.
I haven’t washed them yet. I hope they wash well.

I have really bad cold issues, have to wear double/triple layers of clothing in the northwest winter. Multiple layers of socks weren't cutting it, tried using Hottie packets all over between layers. These socks work great for warming the bottoms of my feet (use high then medium heat levels). Wires on the side and bottoms don't bother me, don't feel them. Like that these come up to knees.

These are amazing! I go to a lot of NFL games (The Patriots of course) and I always just need a little more warmth during the colder football games. These are just what I needed. They charge up and are ready to go for game days. I like that they also don't fall down - they stay up and tight in my boots. Absolutely love them!

I bought them as a gift because winter started and most of the time he works outside, these socks worked perfectly and are very comfortable also the material is of good quality a good cotton, Also As it appears in the description it keeps more than 10 hours warm It is easy to set the temperature if it is low or high and it also heats up quickly without having to wait too many minutes. The batteries are rechargeable and light green when they are fully rechargeable, on the other hand they are not heavy batteries and they have no problem with making them uncomfortable with pants.
What a great product and I'm glad I found it!

I always complain that my feet are cold. No more! Nicely made sports socks with rechargeable batteries for built-in heat! Batteries are a bit bulky, but easy to charge and the heat they produce is very pleasant.
