Description

58% of the blend.
Features
  • Merino wool blend. 58% Merino carries the warmth, the moisture management and the odor resistance; the nylon and elastane carry the durability and the shape. Full blend: 58% Merino wool, 40% recycled nylon, 2% elastane.
  • Full cushion. Full cushion across the shin, calf and foot — the warmest, most padded option in the kids' line, for cold days and boots that rub.
  • Flat knit toe seam. A flat knit toe seam rather than a stitched ridge, so there is no bump across the toes inside a boot.
  • Over-the-calf height. The cuff finishes above the boot cuff rather than under it, so there is no sock edge trapped between a hard shell and the shin.
  • Odor resistance. Merino resists odor build-up, so a pair aired out overnight is wearable again the next day — the practical reason to ski in wool.
Size & Fit

Smartwool sock sizes run off shoe size — check the Smartwool sock chart on this page. Offered in XS, S, M, L. Over-the-calf height finishes above a ski or snowboard boot cuff rather than under it. Kids' sock sizes follow kids' shoe sizing, which restarts after 13.5 — so M covers 12 through 2.5 and L covers 3 through 6.

M 12 - 2.5 29 - 32 11 - 13.5

Kids' sock sizes follow kids' shoe sizing, which starts over after size 13.5 - so size M covers 12 through 2.5, and size L covers 3 through 6.

Smartwool socks run true to size, based on your total foot length - and calf circumference for compression socks. Smartwool socks are designed to retain their fit and shape; following the care instructions on the label will help avoid shrinking or stretching.

Medium thickness with full sock cushioning.

Warmth

Very warm

58% Merino at 63 g (2.21 oz) over the calf. A cushioned sock traps more air, so it is the warmer choice.

Durability

A Merino and nylon blend with no additional reinforcement published for this style — a standard-duty sock rather than a reinforced one.

Bulk in the boot

Full cushioning takes up real room. If your boot is already snug, size the sock down in bulk, not in length.

Best for

Is this right for you?

Ski and snowboard lessons

Over-the-calf height means no sock edge trapped between a hard boot cuff and the shin — the thing that ends a lesson early.

Not for: Not an everyday sock: over-the-calf Merino is more sock than a school shoe needs. Try the Kids' Ski Light Cushion socks

Sledding and snow play

Merino keeps insulating when it gets damp, which is what happens to every sock inside a snow boot by lunchtime.

Not for: A wet sock is still a wet sock — bring a spare pair for a full day out. Add the Kids' Thermal Merino Neck Gaiter

Winter boots

Warm enough for walking-around winter boots, and odor-resistant enough to go more than one day.

Not for: Above about 50°F this is more sock than most kids want. Add the Kids' Merino Gloves

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
How do I pick a sock size?

Smartwool sock sizes run off shoe size, not foot length in inches. The Smartwool sock chart on this page maps each size to US, Euro and UK shoe sizes. This style is offered in XS, S, M, L.

What does full cushion mean?

Smartwool's own definition for this style: “Medium thickness with full sock cushioning.” Full cushion across the shin, calf and foot — the warmest, most padded option in the kids' line, for cold days and boots that rub.

Can I wear these more than once between washes?

Yes — that is one of the practical reasons to ski in wool. Merino resists odor build-up, so a pair aired out overnight is fine for a second and often a third day. Wash them when they are actually dirty.

Will they shrink?

Not if you follow the label. Machine wash on a gentle cycle in warm or cool water and tumble dry low. High heat is what shrinks and felts a wool sock — a hot dryer will do more damage than a season of skiing.

Do I need a liner sock under these?

No. One Merino sock is the right answer in a modern boot; two socks bunch, trap moisture between the layers and cause more blisters than they prevent.
