How long does the battery last?

Savior Heat rates the low setting at up to 6.5 hours, medium at 3 to 4 hours and high at 2 to 2.5 hours. Cold weather and thick socks can shorten those times.

Can I control the heat without the app?

Yes. A button on the sock cycles through high, medium and low, marked by red, white and blue LEDs. The app adds remote control but is not required.

How do the batteries attach?

Each sock has a pocket on the outer side of the calf that holds its 2200mAh battery. A dual charging cable tops up both packs at once.

Are they machine washable?

The batteries and cables must come out before washing. Wash the socks gently and let them air dry, since heat and tumbling can damage the carbon fiber elements.

What comes in the box?

A pair of heated socks, one 2200mAh battery per sock, a dual charging cable, a user manual and a gift box.

Are they good for skiing?

Yes. The knee-high cut fits under ski boots and the wrap-around forefoot heat targets the toes that go numb on lifts. The medium setting is the usual choice for active skiing.
