The Snow Deer Heated Socks are rechargeable ski socks with a 7.4V battery that heats the front foot, toe and sole through a far-infrared element. Three heat levels run from roughly 2.5 to 8 hours per charge, and the Coolmax, elastic and spandex blend is meant to wick and stretch. They suit skiers, hikers, riders and anyone with cold feet outdoors. Against plain wool ski socks they add on-demand warmth, but they need charging, hand washing and battery care that ordinary socks never ask for.

These rechargeable heated socks run on a 7.4V battery. A far-infrared heating element warms the front of the foot, the toes and the sole. They are made for skiing, cycling, motorcycling, hiking, fishing, hunting and other outdoor activities.
Three heat levels are shown by the indicator light: red is high, white is medium and blue is low. Heating temperature ranges from 40 to 65°C, and heating time ranges from 2.5 to 8 hours.
Charge the battery fully before first use, then connect it to the wire in the battery bag next to the sock. Put the socks on and long press the power button for 3 seconds to start. After that, short press to change the heat level.
