Will heated socks fit inside my ski boots?

Most heated socks are designed to add minimal bulk. The heating elements are thin textile strips, and the main bulk comes from the battery pouch at the calf. If your boots are already tight, choose an ultra-thin option like the Therm-ic PowerSock. Never size down your socks to compensate — this restricts circulation and makes cold toes worse.

Can I wash heated socks in a machine?

Some heated socks are machine washable on gentle cycle after removing the batteries. Others recommend hand washing only. Always check the manufacturer's instructions. Never put heated socks in the dryer — heat can damage the heating elements and battery connectors. Air dry only.
