FAQ: Choosing Socks
How do I pick the best sock for me?
What size sock do I wear?
We recommend choosing your sock size based on your shoe size. You can do this using our sock sizing charts, which are included on each sock page and on our Sizing Charts page.
Are your socks unisex sizing?
Most of our socks are sized based on men's, women's, and kids’ shoe sizes, with a few styles offered in unisex sizing. Depending on an individual's shoe size, a lot of our socks can be worn by anyone. See our size chart for size conversions.
What is the difference between the heights of your socks?
You can see the different sock heights we offer and how they compare to each other on our Sizing Chart page, which includes a measurements chart with the average length from heel to cuff for each sock height.
What are the different weight options for your socks?
The sock weight (or yarn weight) refers to the fineness/thickness of the yarn used in the knit. We currently have 4 different sock weights; from lightest to heaviest, they are Ultra-lightweight, Lightweight, Midweight, and Heavyweight.
These combine with our 3 cushioning levels to create a range of support, warmth, and comfort in our socks. Try different combinations of cushion and weight to find the perfect balance for you.
What are the different cushion levels of your socks?
Sock cushion is created by knit terry loops. The cushion provides added protection in high impact areas, shock absorption, and extra warmth and comfort. Our 3 cushioning levels are No Cushion, Cushion, and Full Cushion. You can learn more about these levels on our Size Guide page.
A few of our Ski & Snowboard socks feature targeted cushioning in the shin that is separate from the foot. In our Work category, we also carry socks specifically for steel-toe footwear with extended cushioning in the toe.
Do you make a sock that's 100% wool?
No, we do not make any socks that are a 100% wool; instead we use three simple materials (merino wool, nylon, and Lycra) to give our socks their signature fit and durability. All our wool socks include some nylon to increase their durability and Lycra to improve their comfort and fit.
Should I buy your Coolmax socks for summer?
"Coolmax" is the brand name of the synthetic fiber we use in many of our non-wool socks. Coolmax mimics a lot of the same performance properties as merino wool and is a good alternative if you are unable to wear wool products. Otherwise, we recommend sticking with our merino wool sock styles.
What is the thickest, warmest sock that you make?
The thickest, warmest socks we have are our Heavyweight socks, available in select Hunting, Tactical, and Mountaineering styles. The Mountaineering Socks are 25% thicker than our standard cushion socks and are available in micro crew and over-the-calf heights with cushioning throughout the sock.
What is the thinnest Darn Tough sock I can buy?
I have diabetes and need a compression sock. Which Darn Tough socks do you recommend?
We don’t make medical-grade compression socks; however, we do make several Light Compression socks that offer the optimal amount of compression to help speed your recovery from activities. These over-the-calf socks are perfect for skiing, running, and everyday light support.
I have thick calves; do you make models that accommodate larger calf sizes?
All of our socks are designed to have a snug performance fit. We don't make any sock styles that are specifically for wider calves, but the fit from style to style will vary slightly based on the material mix and knitting technique.
Why do my Darn Tough socks feel tight?
Our socks have a snug fit because they are knit with performance in mind. The better fitting the sock, the more durable it will be over time and the better they will perform.
Do I need to wear sock liners with your socks?
Nope. Long ago people used sock liners to compensate for socks that fit poorly, but you won’t find that problem with Darn Tough socks.
