Best wool socks brands
Updated October 15, 2026
Wool is the most practical natural fiber for socks. It regulates temperature across seasons, wicks moisture without holding it against the skin, resists odor between washes, and outlasts cotton by a significant margin. Merino wool — finer, softer, and well-suited to direct skin contact — is the dominant choice for everyday and athletic socks. The brands below work with wool and merino and are listed in The Plain Thread directory. Most make socks alongside other wool accessories and apparel.

Common questions about wool socks
Are wool socks worth it?
Yes — wool socks outperform cotton and synthetic alternatives in almost every practical way. Wool regulates temperature so your feet stay comfortable in both cold and warm conditions. It wicks moisture and resists odor far better than cotton, meaning you can wear wool socks multiple times before washing. Wool is also naturally durable: a well-made pair of merino or wool-blend socks will outlast several pairs of cotton socks. The higher upfront cost is offset by longevity and performance.
What is the difference between wool and merino wool socks?
Merino wool is a specific breed of wool known for its finer fiber diameter — typically 17 to 24 microns, compared to 30 microns or more for standard wool. The finer the fiber, the softer the sock against skin. Standard wool socks can feel scratchy to some people; merino wool socks are generally soft enough to wear directly against sensitive skin. Both share wool's core benefits — warmth, moisture management, odor resistance — but merino is the better choice if comfort against bare skin is a priority.
How long do wool socks last?
A quality pair of wool socks lasts two to five years with normal use and proper care. Key factors: fiber quality (higher micron counts can pill faster, while tightly spun yarns hold up better), construction (reinforced heels and toes extend life significantly), and washing habits (machine washing on cool and air drying prevents fiber breakdown). Brands that use nylon or reinforcement fiber in the heel and toe area will outlast 100% wool socks in high-abrasion zones.
Are wool socks good for hiking?
Wool socks are the standard choice for hiking, particularly merino. They manage moisture without holding sweat against the skin, which reduces blister risk. They insulate even when wet — critical if conditions change on the trail. They resist odor on multi-day trips where washing is not possible. Most serious hiking sock brands use merino wool, often blended with a small percentage of nylon for heel and toe durability. Look for cushioned construction and a seamless toe if you are covering significant mileage.
Do wool socks shrink?
Wool socks can shrink if washed in hot water or dried on high heat. The felting process — where wool fibers interlock and compress — is triggered by heat combined with agitation. To avoid shrinkage: wash in cool or cold water on a gentle cycle, or hand wash. Reshape while damp and air dry flat. Most wool sock brands pre-treat fibers to improve machine washability, but the safest approach is always cool water and air drying. Merino wool is generally more resistant to shrinkage than coarser wool types.
