Choosing the best socks for you is waaay easier when you understand which qualities make a sock right for a given activity.

Read on to learn more than you ever imagined about material, fabric weight and sock height!

We watch our weight! 

Fabric weight, that is. Ultralight, light, medium, heavy and extra heavy, the type of padding and insulation you’ll need in a sock varies depending on your activity. Fabric weight describes the warmth and padding level of a sock. Skinny knits are best when you need a close fit, while thicker fabrics provide excellent cushion and insulation. A heavy cushion sock is best if you’re on your feet all day while an ultralight sock will minimize blistering if running is your thing. Our Sock Finder can help you select the perfect fabric weight for you.

Right sized!

No show, knee high or micro crew, has the right sock height for each shoe or activity. Sock height describes the highest point a sock reaches on the leg. Choosing the right height for the activity you’re doing will help provide extra comfort and protection for your shins, legs and feet. has wide range of heights: crew, knee high, no show, quarter crew, boot, ¾ crew, micro crew, thigh high, calf sleeve and tights. Use our Sock Finder to find which sock height works best for whatever adventure you have planned! 

Material matters!

Fabric content determines whether a sock is best for hiking, running or everyday wear. Information about the fibers used in our socks can be found easily on the product page. 


A synthetic fabric that has excellent wicking properties. It’s light weight, soft, warm and quick drying. An acrylic/wool blend is good for outdoor activities in cold weather.

Brands: Fox River, Under Armour, Wigwam


A strong, soft fiber that retains body heat well when dry and is comfortable to wear in all types of weather. 100% Cotton fibers are best for dress or casual socks, since cotton fibers stretch and bag easily, which can lead to blisters. Cotton socks often blend some synthetic fibers into the weave so you can have the best of both worlds; the softness and durability of cotton, along with the elasticity and high tech moisture management of synthetics.

Brands: Fox RiverWigwam, Toesox, Under Armour


A moisture-wicking technical fabric developed by DuPont in 1986. It is fade and shrink-resistant and is often combined with cotton, wool, or Spandex. Best used during extreme physical exertion and in combination with other materials to provide warmth.

Brands: Fox River, Injinji, Wigwam, Wrightsock


A soft, napped fabric, normally made from a 100% synthetic material like polyester. It is warm, soft and easy to clean.

Brands: Acorn

Nylon (aka Polyamide)

A polymer fabric that is extremely strong, absorbs more water than other synthetics, is light weight, and easy to clean. It is best used in garments that undergo a lot of stretching and pulling, like tights.

Olefin (CoolMax)

A very light weight fabric that is extremely strong, quick drying, easy to clean, stain and soil resistant, and comfortable to wear. Olefin is one of the best fibers for both repelling water and wicking water away.

Brands: DryMax, Fox River, Under Armour, Wigwam


A synthetic fabric that is quick drying, strong whether wet or dry, wrinkle resistant and easy to clean. It is more breathable and absorbent than nylon.

Brands: Balega, Darn Tough, Toesox, Under Armour, Wigwam, Wrightsock


A “super” waterproof fiber with extreme moisture wicking capabilities. It is strong, stain resistant, very light and rivals wool as an insulator.


The strongest natural fiber. It is elastic, absorbent and has top-notch insulating properties similar to wool. Silk is comfortable to wear year round and is dirt resistant but light and sweat sensitive, requiring regular care and cleaning.

Brands: Wigwam


A synthetic fabric that can be stretched more than 500% without breaking. It is stronger and more durable than rubber yet lightweight, soft, easy to clean and provides an excellent combination of comfort and fit without bagging or sagging.

Brands: CEP Compression, DryMax, Injinji, Toesox, Under Armour, Wigwam

Wool (Merino, Mohair, Other)

An exceptionally soft, durable natural fiber that keeps the body at an even temperature by insulating instead of trapping heat. Wool keeps you cool in hot weather and warm in cold weather. Superior breathability and wicking properties prevent clamminess. The natural elasticity of wool fibers allow garments to stretch and then return to their original shape, preventing sagging and bagging. Wool is super absorbent so it dries slowly but retains heat even when wet. It is also naturally fire resistant.
