Questions, answered
Are your heated socks battery-powered?
No. Our heated-style socks are thermal: a thick, brushed interior traps your body heat. There are no batteries or wires, so they’re machine washable and ready whenever you are.
What does TOG mean?
TOG measures how well a fabric holds in heat. The higher the TOG rating, the warmer the sock. Styles that have been rated show the number in their listing.
Merino wool or lamb’s wool?
Both are naturally warm and breathable. Merino has very fine fibers that feel especially soft against the skin, which makes it a favorite for hiking and long wear.
What size should I get?
Sock size 9–11 fits most women’s shoe sizes 5–10, and sock size 10–13 fits most men’s shoe sizes 6–12. Each listing shows its exact sizes.
How fast is shipping?
Orders ship within 1–2 business days by USPS and usually arrive 3–5 business days later. Shipping is free on every U.S. order.
Can I return them?
Yes. New and slightly used items can be returned by mail within 14 days of delivery, with no restocking fees. See our refund policy.
