Sock Height
Sock heights are relatively universal. We admit we invented Micro Crew on our own. The below visuals can give you the general idea, and the socks lengths chart will help with specific measurements.

Sock Height (Inches)
We measure from the heel to the top of the sock. Feet or shoe sizes can help you determine the position of the sock on the leg, but the actual measurement results may vary due to everyone's leg length.
| Sock Height | Men's/Unisex | Women's | Kids |
|---|---|---|---|
| No Show | 2" | 1.75" | – |
| Hidden/No Show | 3.5" | 2.75" | – |
| 1/4 Sock | 5.5" | 5.5" | 4" |
| Shorty | 6" | 5.75" | – |
| Micro Crew | 8.5" | 7.5" | 6" |
| Crew | 10.5" | 8.5" | 7.5" |
| Boot | 11" | 10.5" | – |
| Mid Calf | 12" | 12" | – |
| Over the Calf/Knee High | 17" | 16.25" | 13" |
Sock Cushioning
Cushioning is the filling made of knitted wool in the sock. Cushioning can provide extra protection in high-impact areas, absorb impact, and bring extra warmth and comfort.
1. No Cushion
Thin knit, the sock's lining is not covered with wool. Even if there is cushioning, these socks are naturally light and thin, with no comparison.
2. Light Cushion
Almost all of our sock types use the most extensive cushioning. Cushioning, some people think this weight is the most perfect combination of our knitting.
3. Full Cushion
The terry cloth is thicker and the sock is longer, or it is mainly used to keep the body warm, which is the most comfortable cushioning for the feet and provides the best cushioning.
Some of our snow socks are cushioned at any position on the ground, which is consistent with the part. In our work sock category, we also provide socks with steel toe reinforcement, which have extended cushioning function at the toe.
Socks Size FAQ
How do I determine socks size?
To determine socks size, first confirm your shoe size. Shoe size will tell you a larger socks size. Our socks sizes correspond to 2-3 shoe sizes. If your size is between two size categories, please choose the larger one. For more information, please refer to our socks size chart.
Are all socks one size fits all?
Socks are not one size fits all, but our various socks sizes are suitable for several shoe sizes. Because socks are elastic, they are suitable for different foot types; therefore, in order to achieve the best effect, you need to fit the appropriate socks size. For more information about sizes, please refer to our socks size chart.
Are socks sizes the same as shoe sizes?
Socks sizes and shoe sizes are not the same; however, your shoe size will help you determine your socks size. For example, if you wear size 11 shoes, you need a pair of men's large socks, because men's large socks are suitable for sizes 10-12.
What size socks do I need?
If you are not sure how many large socks you need, please check your shoe size first, refer to our socks size chart, and then choose the socks size corresponding to your shoe size. If your size is between two sizes, we recommend choosing the larger size of socks.
What size socks do I wear?
If you have never worn Darn Tough socks before, please be sure to check our socks size chart and compare your shoe size with our socks size (if your size is between two sizes, please choose the larger one). If you have a pair of our socks, but are not sure of the size, please check the inside of the sock, we will all knit the size (for example, "M" means medium).
