Cold feet can ruin a day outside faster than anything else. If you've decided to try heated footwear, you've probably narrowed it down to two options: heated insoles or heated socks. Both work, but they suit different people. Here's how they compare.
How each one works
Heated insoles replace the insole in your boot. The heating element sits under your foot, usually focused on the toes or forefoot. Wireless versions have the battery built into the insole and are controlled with a remote.
Heated socks have heating wires knitted into the fabric, usually over the toes and top of the foot. The battery typically clips onto the top of the sock at the calf.
Side by side
| Heated insoles | Heated socks | |
|---|---|---|
| Where the heat is | Under the foot | Over the toes and top of the foot |
| Battery | Often built in (wireless) | Usually a pack at the calf |
| Fits in | Boots with a removable insole | Most footwear |
| Washing | Wipe clean, not washable | Washable with battery removed |
| Swap between boots | Move them to another pair | Wear with any boots |
When heated insoles make more sense
- You already own good winter boots and want to make them warmer.
- You don't want a battery pack at your calf or a cable running up your leg.
- You stand on cold ground: ice fishing, hunting stands, outdoor work on concrete or snow.
- You like adjusting the heat from a remote without taking anything off.
When heated socks make more sense
- You want heat over your toes as well as underneath.
- You wear tight ski or skate boots where a thicker insole won't fit.
- You want something you can machine wash regularly.
Things to check either way
- Fit. Insoles need the right size (or trim lines) and enough room in your boot. Socks need a snug fit so the heat reaches your skin.
- Runtime by setting. Ask for measured figures, not just the maximum.
- Battery documentation. Lithium batteries under your feet should come from a seller who can tell you exactly what's in them.
- Overheat protection. Check how the product controls its temperature.
The bottom line
If you want to upgrade boots you already own and hate cables, heated insoles are the simpler choice. If you need heat over your toes or wear very tight boots, heated socks may suit you better.
