These heated ski socks also provide maximum comfort in the sensitive areas of the foot, namely the shin, calf and instep. Equipped with Moisture-Vent Technology, this ski sock efficiently wicks away moisture from the arch of the foot. Thanks to the macro-channels around the foot, moisture is guided away from the ski boot, making it easier for your foot to breathe. The Powersocks Heat Fusion offer a soft and pleasant warmth around the toes and provide up to 16 hours of warmth, depending on the type of battery used. The socks are sold without batteries. 

Instructions for use
• Remove the batteries before washing the socks
• Turn the sock inside out before washing
• Wash the socks in the washing machine at 30° maximum with a low spin
