Care and Cleaning

Damaging your wool socks in the wash is frustrating.

Worried about shrinkage? Fearful of stretching or unraveling?

Cleaning is actually super easy. Read this guide, and caring for your wool socks will be a breeze.

[Will they shrink?]
Our wool socks are specially treated for shrink-resistance before leaving the factory, keeping them from losing shape over long-term wear and washing.
▶ Machine wash or soak and gently hand-wash sweaty areas; water temperature should not exceed 40°C (104°F).
▶ Tumble dry on low or air dry in the shade. Tip: Turn your socks inside out and place them in a laundry bag when machine washing to maintain the loft and cushioning of the inner terry loops.

[How to choose detergent?]
⚠️ Remember the golden rule: Wool contains keratin (essential for antibacterial and odor-resistant properties), and acidic or alkaline substances can break down proteins!
Therefore, we recommend: Using a neutral detergent (look for a gentle formula with a pH of 7). Do not use baking soda (mildly alkaline), soap, bleach, detergents with enzymes, or fabric softeners.

What is CUSHION?

CUSHION is made of TERRY LOOPS knitted into specific areas of the sock. Cushioning increases comfort and warmth while providing extra protection in high-impact zones.

	No Cushion
	High-density cushioning underfoot
	Extra padding in targeted areas like the shin, in addition to the sole; typically used for ski socks
	Cushioning added to the leg of the sock, in addition to the sole
	High-density cushioning throughout the entire sock (including the top of the foot)
