For a perfect manteinance we suggest:
Initial water temperature should not exceed 30C or 65 to 85F, and with low spin speed.
No bleach product may be used. The sock is not colorfast or structurally able to withstand any bleach.
A machine dryer may not be used. Usually accompanied by an alternate drying method symbol.
Socks may not be smoothed or finished with an iron.
Socks may not be commercially drycleaned.
It's always better to turn inside out your socks before washing them, especially socks with embroidery, stripes and special designs.
