Mobile Warming Heated Socks With Lithium Battery

I LOVE THESE SOCKS!! so much that I bought a pair for my husband.
Super excited to give them to him for our big ski/hiking week in Vermont-they came in time-I wrapped them up and gave them to him for his birthday a week prior to our vacation. Do order these fantastic warm socks!

Couldn't be happier. Long lasting warmth and comfort. The only thing I would change: The general one size fitting - (S/M) instead of specific sizing. The socks are a little too big for me and can be difficult to fit into my shoes easily.

I purchased these rechargeable heated socks for a winter trip to Yellowstone National Park. My hands and feet stay colder than the average person's so I knew I needed some heat on my toes for the freezing temps in the park. I used these socks for three days in a row and I made sure to charge them all night prior to use/reuse. On average I would say the charge in each battery held for a maximum of six to seven hours per day. I toggled between setting one and two because I wanted the charge to last for as long as I was outside in the elements. I figured if I kept it on high (setting three), the batteries would not last long at all. I was correct. I turned them on at around 7;30 each morning after already having them on my feet obviously. It was single digits most mornings. We returned after 3pm each day and my batteries were already dead by then, but my feet were not totally freezing. I always started on setting one (low) and wondered if they were even working on the first day. It is difficult to determine if they are putting out heat or not. I checked them to see if they were heating at all by taking my boot off and feeling the sock. It appeared to be warm and a friend agreed with me after feeling the sock as well. So I knew they were working, so I booted back up and went the remainder of the day with toes that were warm. When I knew I would be walking thru the snow, I bumped it up to the second setting for a bit, but not too long. I could feel the difference by pressing my toes to the floor. That's how I knew they were heating up more. I did this for three days and had no real complaints. My peers on the trip did not fair the same. They used toe warmers (those portable warmers that stick to the underside/outside of your socks). They were changing these throughout the day because they just would not last as long. They also took off their shoes to apply direct heat to their socked feet. I never had to do this. I wore sock liners under these socks. One day, after walking in snow, my socks were a bit wet when I took them off in the afternoon. I might blame my snow boots for this, but honestly I am not sure how the socks got wet (sweat or leakage thru boot). My socks were damp each day upon taking them off, but my liners and feet were dry, too. I went snowshoeing another day and the socks were not wet that day, so who knows. It only happened once. I just dried them with a hairdryer and then recharged them. I wore them three total days without washing and they never smelled. I would not recommend washing them in a washing machine. I may hand wash mine later, but as for now, I do not intend to use them again. I live in Georgia where it never gets cold enough to warrant using them.

I have only worn them once and a 30 degree day and they kept my feet toasty. Iā€™m a mail carrier and itā€™s important Iā€™m comfortable while Iā€™m delivering my mail and again Iā€™ve only worn them once but I was comfortable. Iā€™m ordering another pair so I can have them on rotation during wash days

So far seems to be OK, just had them 1 wk.
