Find your hiking-sock size in the right brand chart.
A medium in one chart can mean something different in another. Use the chart for your chosen model, then check the fit in your footwear.
Use the size of your foot
If you buy larger hiking shoes for extra space, their label can produce an oversized sock. Enter your actual foot’s size in the published US, EU or UK system. This field is not a foot length in centimeters.
Choose the chart for the exact model first, then its US men’s, US women’s, EU or UK column. Those columns are numbering systems; a model’s men/women/unisex label identifies its chart family. See foot measurement and chart examples.
Example: US men’s 9.5 in the Darn Tough men and unisex chart.
M
Darn Tough advises sizing up between sizes. Chart coverage does not mean every model is sold in every listed size.
| Sock size | Shoe range |
|---|---|
| XS | 2.5–5 |
| S | 5.5–7.5 |
| M | 8–9.5 |
| L | 10–12 |
| XL | 12.5–14.5 |
| XXL | 15–17 |
When the chart does not settle the choice
An overlapping boundary can produce two results. Use that chart’s between-size guidance rather than averaging two sock sizes. A gap or unsupported size system stays unanswered; this tool does not invent a shoe conversion.
Match the chart to the exact model and check heel position, toe room and cuff height in your footwear. A published range is a starting point, not a promise about how a particular knit will fit. Use the hiking-sock fit checks before comparing extra cushioning or another layer.
