Merino: the fiber that goes beyond base layers
Temperature regulation, moisture control, breathability, warmth — merino wool brings the same natural benefits to any piece of a winter kit, not just what's against skin.
That’s why Smartwool goes beyond base layers, creating reliable merino solutions for any cold-weather activity your customers take on. Discover new ways Smartwool puts the fiber to work, from insulated outerwear to performance ski socks.

How to choose a ski or snowboard sock
Smartwool offers a full range of merino socks designed for skiing and snowboarding. Every style is odor-resistant, moisture-managing, ZQ Wool Certified and made in the USA — but that doesn’t mean any pair will work for anyone. The right recommendation comes down to cushioning level, which influences warmth, thickness and the feel of boots.
Here’s what to know about each level and how to find the right sock for you or a customer.
Zero cushion
Slim, non-cushioned fit for less bulk. Best for newer, tighter boots or those who prefer the most precise, performance-oriented fit.Targeted cushion
Padding and mapped mesh zones at toes, heel and shin. Smartwool's most popular level and athletes’ favorite, it has just the right amount of cushion to complement boot fit without sacrificing feel.Full cushion
Cushioning throughout the entire sock delivers more warmth, impact protection and durability. The heaviest in the lineup, it’s the go-to for a more forgiving boot fit.Additional options
For some, cushioning is only part of the equation. Many Smartwool ski/snowboard socks come in these options:
- Extra stretch for those with fuller calves.
- Ski compression (with 20-30 mmHg of graduated compression) for those who need extra support.
Spotlight ski sock: Intraknit™ Zero Cushion
The new Intraknit™ Zero Cushion is a no-bulk, race-ready ski sock that delivers a precise, responsive fit inside tight performance boots. The secret: 3D-knit technology that provides articulation, ventilation and minimal cushioning where it matters most. Recommend it to ski racers or technical skiers who want to feel every edge.
Key features:
- Anatomical extended welt contours around the knee, adds coverage and improves comfort
- Graduated cushioning and cuff shape creates a breathable performance fit without sacrificing cushion
- Indestructawool™ for better durability
- 4 Degree™ Elite Fit System locks in a precise fit
- Body-mapped mesh zones keep feet breathing
For backcountry skiers who could benefit from 3D-knit technology but have more wiggle room in their boots than racers, suggest the Intraknit™ Targeted Cushion Ski Sock.
