The ActionHeat. It runs 4+ hours on high, 6+ on medium and 8 on low. The Gerbing runs 3 hours on high, 5 on medium and 7 on low.

Is the Gerbing worth it over the ActionHeat?

If price matters most, yes. The Gerbing is $74.95 at eBay versus $89.99 at Amazon as of November 4, 2026, about $15 less, but you give up roughly an hour of heat at each setting.

Which is warmer at the top setting?

They tie. Both top out at 140F on high. The difference is how long they hold it: 4+ hours for the ActionHeat, 3 hours for the Gerbing.

Can I machine wash either pair?

The ActionHeat is machine washable on gentle cycle in the provided mesh bag. Gerbing's listed specs do not state washing instructions, so check the tag before washing.

Do both come in the same sizes?

Yes. Both come in S/M, L/XL and XXL.

Which has better materials?

The ActionHeat lists 50% wool with cotton and Lycra. The Gerbing lists wool, nylon, acrylic, polyester, spandex and rubber without percentages, so the ActionHeat is the more clearly wool-heavy sock.
