Wool Sock Allergies

Many people complain that wool socks itch and cause their feet to get hot and uncomfortable and think it is a wool allergy. What they are really experiencing is a reaction to the coarse hair of poorly processed wool. Most itchy reactions are considered a form of dermatitis or irritation to the skin.

Under-processed Wool

Most people do not have a true wool sock allergy. What they are experiencing is a reaction to the fine hairs of the wool yarn.

True Wool Allergy

A true allergic reaction will cause hives, blisters, sneezing and swelling. It can be caused by the wool itself or chemicals used to treat or dye the wool.

Lanolin Allergy

The most common kind of wool sock allergy is an allergic reaction to the lanolin in the wool itself. Since lanolin is an oil you can wash a certain amount of it out, but you can never remove all the lanolin in wool.

Wool Blends

Some people who cannot wear sheep's wool can wear softer wool blends. Some common blends include: wool and alpaca; wool and acrylic; and wool and cotton.

Alternative Style Wool

There are several alternatives that are just as warm or warmer than sheep's wool, such as alpaca, camel, cashmere and yak.

Allergies to Other Fibers

Many socks have processing agents and antibacterial agents sprayed on them before shipping. These chemicals used in post-manufacturing may cause allergic reactions.
