These heated socks are great for winter, chilly offices, or if you get cold feet easily. My office is always blasting the AC so I've gotten a lot of use out of these socks on their low heat setting to keep my feet at just the right temperature. Operation is easy. After connecting the battery via the sock's integrated USB-C cable, long press the power button on the side to turn it on and short press to toggle between high, medium, or low heat. Powering off is also a long press of the button. The batteries have LED indicators for remaining charge and current heat settings. They also recharge via USB-C and a pair of USB-C to A cables are conveniently included. Using a 10 W (5V/2A) charger, it takes around 4 hours to charge from nearly depleted. The batteries are slimmer and lighter compared to another pair of 5000 mAh heated socks I own. If I do a light jog, the sock cuffs still manage to stay up but vigorous running will make them droop down. The heating elements are concentrated along the top of your toes and the ball of your feet with the heat on the bottom tapering off towards the midsole. As it's your extremities that get cold first, this keeps your feet nice and warm. That said, I wish there was heating along the top of the ankle since that part often gets exposed depending on your shoes' cuff height and the pants you're wearing. I found for my pair that the right foot warms up slower and not as warm as the left oddly enough. As for fit, I'm between 41 and 42 which is in between sizes according to their sizing guide, so I opted for Medium as I prefer a tighter fit; the foot is just how I like it but the cuff is a bit tight. After a few wears and washes, they have loosened up a bit though. When I first wore them, they were much tighter. The fabric is comfortable to the touch. In the 3 weeks since I've been using this, I have yet to encounter any irritation. I recommend filing your toenails though. There's a lot of loose fabric/threading that can snag on rough or uneven toenails when putting them on. Another feature I really liked is the pocket flaps' magnetic snap buttons for the battery pockets. Compared to traditional buttons and regular snap buttons, it's far easier to fasten. Regarding the battery pockets, I do wish that they were a tad deeper as I found the batteries don't sit fully inside the pockets and protrude slightly above the opening. That said, the pocket flap and the batteries' weight keeps them from falling out; I just prefer not having the power connection exposed in any way though. They can be machine-washed and a laundry bag is conveniently included; no tumble drying though. Alongside my regular laundry, I machine washed on cold with a gentler spin cycle using the laundry bag and they've come out without any problems. I then use a drying rack that has some sock prongs to air dry them. Quality has remained the same after several washes. There's also a companion app to use with these socks. It's pretty simple to use with a straightforward interface. It lets you control each sock separately or both at the same time. Heating is still only 3 levels of low, medium and high; unfortunately, there's no greater granularity even in the app. In addition to powering off, the timed shutdown feature is handy and I also really like that it allows you to turn off the indicator LEDs on the battery. It also has a battery indicator, albeit it's not percentage, just bars. It uses Bluetooth to communicate so you do have to enable location permissions though. As it's not winter yet, there hasn't been a chance to try them in more extreme temperatures, but based on my testing at home, I would say they would complement snow boots well but would not suffice for trying to use lighter footwear in the winter, at least for southern Ontario winters.
