Therm-ic PowerSocks Heat Fusion One heated socks

The PowerSocks Heat Fusion One heated socks keep your feet warm while skiing, snowboarding, winter hiking and other outdoor activities. The heating element at the front of the foot warms the toes from both below and above, right where they are most sensitive to the cold.

The Heat Fusion technology distributes heat evenly and ensures thermal comfort even at low temperatures. The snug fit adapts to the shape of your foot and provides support without adding unnecessary bulk inside the boot. Targeted padding on the shin, heel and toe reduces pressure points in the most stressed zones, and technical fibres support thermoregulation as you move.

The batteries attach with patented snap buttons and the wide elastic ribbed cuffs keep them securely in place. The socks are sold without batteries, so choose compatible Therm-ic S-Pack batteries, for example S-Pack 2400 or S-Pack 1200. If you want everything in one box, take a look at the Heat Fusion One set with S-Pack 2400 batteries.
