The thin Sidas Ski Race Heat S.E.T heated socks are made for racers and performance skiers who need warmth in extreme conditions but do not want to give up precise contact with the ski boot. The heating uses Smart Elastic Technology (S.E.T): a thin 2 mm heating line routed in an elastic flat seam spreads gentle warmth around the toes without disturbing how the sock sits on the foot.
Polyamide fibres with a high share of elastane provide a snug fit with light compression. The very fine 200-needle knit gives a high-resolution construction without excess loops and cut threads, so the sock transmits the feel of the ski boot better. It also offers functional insulation and good moisture wicking despite its very thin weight.
The socks are sold without batteries. You need compatible Therm-ic S-Pack batteries for heating. For S.E.T socks we recommend the higher-capacity S-Pack 1200 batteries, which provide up to 9 hours of warmth depending on the selected intensity. If you would like the socks and batteries in one box, take a look at the Therm-ic Ultra Warm Comfort S.E.T set with S-Pack 1200 batteries.
