Falke SK4 Advanced Men's Skiing Knee-High Socks

The SK4 Advanced is a knee-high ski sock designed for skiers wanting direct power transmission and precise control. The light cushioning strikes the balance between protection and responsiveness—ideal if you've invested in custom-fit boots and want to feel what's underneath you.

Why we rate it

The 45% polypropylene, 20% acrylic, 20% merino wool and 15% polyamide blend does real work here. Merino handles the warmth and odour resistance; the synthetics wick moisture and dry fast. The 3-layer construction keeps your feet dry without bulk, which matters because wet feet get cold fast and lose sensitivity. The anatomic left/right shaping and light sole padding follow the foot's natural contours, so there's no bunching or pressure points even in a snug boot.

Who it's for

More advanced skiers (intermediate and above) who prioritise feel and control over cushioning. Works best in custom-molded boots or boots with a snug fit. The light padding suits all-mountain and piste skiing where you're pushing the boot rather than being protected by it.

Key features

• Merino wool-rich blend — warmth and natural odour resistance without synthetic smell
• Light sole cushioning — enough protection for comfort, not so much that it dulls your connection to the boot
• Moisture-wicking 3-layer construction — pulls sweat away from skin, dries fast
• Anatomic L/R shaping — socks mould to each foot's shape for a custom fit
• Knee-high length — full coverage in tall boots, with shin and ankle reinforcement

From the fitting room: These socks work brilliantly in stiffer boots because they don't add bulk. If your custom boots feel a touch loose, these won't help you take them up a size—but they'll keep your feet warm and dry on the coldest days.
