Ask anyone who's had a miserable day on the mountain and there's a good chance it started with their feet. Cold toes, rubbing shins or sweaty socks can ruin a day faster than bad snow.
The fix is simple, but it's not what most people expect.
The short answer
Wear one pair of thin to medium, over-the-calf merino ski socks. Not cotton, not two pairs, and not the thickest socks you own.
Why thicker isn't warmer
It sounds backwards, but a thick sock can make your feet colder. Ski boots are built to fit snugly. When you cram a thick sock (or two) in there, you squash the blood flow that actually keeps your feet warm. You also trap sweat, and damp feet get cold fast.
A thinner, well-fitted merino sock lets your boot fit properly, keeps the blood moving and wicks moisture away from your skin. That's what keeps you warm.
What to look for in a ski sock
- Merino blend fabric. Merino regulates temperature, wicks sweat and resists odor. Our Signature Merino Blend™ adds bamboo rayon for a softer, non-itch feel.
- Over-the-calf length. Your sock should sit above the top of your boot so the boot's cuff never touches bare skin. That's what stops shin bang.
- A snug, wrinkle-free fit. Any bunching inside a ski boot turns into a pressure point by lunch. Look for an elasticated arch and a sock that stays up.
- The right cushioning. Cushioning is about fit and feel, not warmth. More on that below.
What not to wear skiing
- Cotton socks. Cotton holds onto sweat and loses its warmth when wet.
- Two pairs at once. Layering socks causes friction, blisters and a worse boot fit.
- Short socks. Anything that stops below the top of your boot will rub.
- Base layers or ski pants inside your boot. Keep your base layer bottoms and ski pants out of your boot. Only your sock should go inside.
How to choose sock cushioning
Choose based on how your boots fit and how you want them to feel.
- Zero Cushion: For tight, performance-fit boots. The most precise, responsive feel.
- Targeted Cushion: A low-volume, precision-fit sock with cushioning focused on the shin to protect against impact. The Goldilocks option for most skiers.
- Light Cushion: Adds light padding under the foot for more comfort, while keeping a close fit.
- Full Cushion: For roomier boots, snowboarders and anyone who wants maximum comfort over long days.

How many pairs do you need?
For a weekend, two pairs is enough. For a week-long trip, pack at least four so you always have a dry pair ready. Merino can be aired out overnight and re-worn, but after a wet day you'll want a fresh pair.
Frequently Asked Questions
What socks should you wear skiing?
Wear one pair of thin to medium, over-the-calf merino ski socks. They keep your feet warmer and drier than thick or cotton socks, and let your boots fit properly.
Should you wear two pairs of socks skiing?
No. Two pairs cause friction, blisters and a tighter boot fit that restricts blood flow, which can actually make your feet colder.
Are thick socks warmer for skiing?
Not usually. Thick socks can squeeze your feet inside your boots and trap sweat, both of which make your feet colder. A thinner merino sock that fits well is warmer.
Can I wear normal socks skiing?
It's not recommended. Normal socks are usually too short, often made of cotton, and don't have the cushioning or fit needed inside a ski boot.
What length should ski socks be?
Over the calf. Your ski sock should sit above the top of your boot so the cuff never rubs on bare skin.
