Yes. The sock is knee-high and the battery sits in a buttoned pocket at the very top of the cuff, above the boot shell, so nothing presses inside the boot.

One size fits most adults. The stretchy knit fits roughly US women's 6–11 and men's 6–11 (EU 37–45), and comfortably over most calves. The sock is about 37.5 cm (14.75 in) tall, so it sits knee-high on most people.

The manufacturer rates the batteries at up to 8–10 hours on setting I and around 3 hours on setting IV. Real-world time is shorter in deep cold, so most skiers run setting I or II and carry the spare set for long days.

Four settings, from a gentle warmth to properly hot. Most skiers live on settings I and II: you stop noticing cold toes rather than feeling heat. Setting IV is for warming up quickly; drop back down once you are warm.

Fit
Nothing pressing inside your boot
The battery rides in a buttoned pocket at the very top of the knee-high cuff, above the boot shell, so your boot fits exactly as it did before.

Why it’s hereBulk inside the boot is the most common complaint about heated socks.

Toe and sole heating
Where ski boots go cold first

Heat
Warmth where your feet need it
The heating element runs under the toes and along the sole of the foot, the first places to go numb on a cold chairlift.

Why it’s hereCold toes end more ski days than tired legs.

If you have reduced sensation in your feet (for example from diabetes or neuropathy), speak to your doctor first and use only the lower settings. Do not sleep in them on a high setting.
