Washing

Machine wash your socks at 30–40°C. Washing at too high a temperature can weaken the fibers and cause them to wear out faster, especially with wool socks.

For wool socks, use a suitable detergent.

Wash them with similar colors and avoid overloading the machine.

Drying

Air-dry whenever possible.

Avoid the dryer, which tends to shrink the fibers.

One last tip: be sure to check the bottom of the drum to avoid ending up with mismatched socks!
