Although it may seem compulsive, ironing socks with a steam iron gets out wrinkles, removing deformities like heel impressions and allowing the hosiery to retain its normal shape. However, since most socks have some artificial fabric content, the right ironing materials and iron setting must be used to avoid singed or shiny socks.
Lay the sock on the ironing board on one of its sides.
Set the iron to its highest setting. You'll be using a press cloth to protect the fibers, so there's almost no risk of damaging synthetic fiber content from high heat.
Lay the press cloth on top of the sock. Iron the garment flat, avoiding the creation of a crisp crease along the top and bottom. Flip it over and do the same to the other side.
Remove the sock and iron the next one.
