Description
Count on dependable warmth and superior comfort with the Pro Merino Heated Socks, crafted from a premium merino wool blend that insulates naturally, draws moisture away, and stays soft on the skin. A calf-length cut, a smooth toe seam, and dense cushioning where impact is greatest make them well suited to long days outdoors. Arch support keeps them secure, as do non-slip details and a toe and heel that have been strengthened, while two heating zones, one over the toes and one beneath them, provide constant warmth. A terrific pick for hiking, hunting, or any cold-weather outing.

User Manual
Technologies

Mobile Warming® Heating Technology
Strong Warmth, Delivered Exactly Where Needed
Mobile Warming® Heating Technology uses very thin, flexible heat pads powered by light rechargeable batteries. Positioned at key spots throughout the garment, the pads give consistent warmth you can adjust at the press of a button, which keeps you cozy whatever the weather, minus extra bulk.

MW Connect™ Bluetooth® Wireless Control
Bluetooth Control at Your Fingertips
With MW Connect® Bluetooth Control Technology you can adjust your heat wirelessly from a smartphone or smartwatch. Switch between temperature levels, monitor the battery and fine-tune your comfort, wherever you are.

Zapsheer™
Static-Free Comfort
Zapsheer™ Technology blends conductive fibers into the fabric to safely discharge static electricity. Static cling is reduced and so is the chance of sparks, a good fit for daily wear and for environments sensitive to static.

Odorsheer™
Stay Fresh, Longer.
Odorsheer™ Technology fights odor where it starts, using antimicrobial properties built into the fabric. Even after long wear your gear stays fresh, leaving you free to concentrate on the adventure instead of the laundry.

SWEATSHEER™ Moisture-Wicking Mesh Liner
Moisture-Wicking Comfort That Keeps You Dry
Sweatsheer™ Technology relies on a high-tech polyester mesh that draws perspiration away from your skin and helps it evaporate faster. Designed for active use, it leaves you dry and comfortable, so your focus stays on the effort however hard you go.
Features

Includes Powersheer® Pro BT 3600mAh Li-Ion Batteries
Longer Warmth, Greater Comfort
The 3.7V Pro BT Batteries deliver large-capacity power (3600mAh) to our top-tier heated socks, which have heating elements beneath and above the toes. Curved ergonomically just like the Micro BT, so they rest comfortably against the calf, they add Bluetooth control through the MW Connect® App, plus a Micro USB port for charging and an LED gauge for remaining battery life—for heat that is smarter and endures longer in brutal cold.

2nd Review
This comes from 1 and half seasons in the deer woods. Once I took them out for the 2nd season, one sock stopped working. The fault was in the sock, not the battery. Fieldsher stood by its 1 year warranty and mailed me a brand new pair, batteries included.
The socks are excellent. They are easy to operate and the heat is easy to control. When temperatures are in the 50s the lowest setting carries me through the full day. In the 30s I normally use low-med and get 8 hours. For a full day in the stand I carry a spare set of batteries and swap them out right there. Every setting gives clearly more warmth.
Any hunter will tell you the feet get cold before anything else. These let me sit in the stand for longer. I also don't need to shift around so much to keep my blood moving.
Expert tips: Pull another warm sock over these to seal in the heat when temperatures drop under < 30 degrees.

Heated Socks
I compared several brands and picked these because the listing said the settings could be controlled through the App. Other models needed buttons on the batteries, and I figured reaching those while out in the field (under layers) would be a hassle, so the App seemed the smarter choice. My first letdown is that the app can't switch the socks on. It lets you change the temperature or shut them off, but each battery has to be powered up by hand first. I get dressed early in the morning before driving to the hunting spot and would rather not drain the battery while I sit in a warm vehicle for 1-2 hours. I wore them 2 days over the last weekend and recharged the batteries in between. The power settings felt the same to me and, honestly, I wasn't sure they were even on. I was hoping to notice obvious heat at the top setting but never did. The weather wasn't extremely cold (a mix of snow/rain) and my feet stayed warm anyway, so that counts for something. I'll try them once more next week... They are expensive, and I wanted to test the least costly model before considering the other options I had in mind for snowmobile season.
