Care and Cleaning

Damaging wool socks while washing is always disheartening.

Worried about shrinkage? Afraid they’ll stretch out or fray?

Actually, cleaning is super easy. After reading this, maintaining your wool socks will be a breeze.

[Will they shrink?]
Our wool socks undergo a specialized anti-shrink treatment before leaving the factory, ensuring they resist deformation over long periods of wear and washing.
▶ You may machine wash or hand-wash in water no hotter than 40°C after soaking, gently rubbing high-sweat areas.
▶ Tumble dry low or air dry in the shade. Tip: Turn socks inside out and place in a laundry bag when machine washing to better maintain the loft and cushioning of the inner loops.

[How to choose detergent?]
⚠️ Remember the golden rule: Wool socks contain keratin (the key component for anti-bacterial/anti-odor properties), and acidic or alkaline substances will damage these proteins!
Therefore, we recommend: Using a neutral detergent (pH 7). Do not use baking soda (mildly alkaline), soap, bleach, detergents containing enzymes, or fabric softeners.

	No Cushioning
	High-density cushioning underfoot
	Cushioning on underfoot and specific zones like the shin (usually for ski socks)
	Cushioning underfoot and extending into the leg of the sock
	High-density cushioning throughout the entire sock (including the top of the foot)
