Smartwool Size Chart

Frequently Asked Questions on Sock Sizing

Do Smartwool socks run big, small, or true to size?
Smartwool socks run true to size, based on your total foot length (and calf circumference, for compression socks). Refer to the sock size charts above to identify which size is right for you.

How do I know what size is right for me?
With proper foot length (and calf circumference, when applicable), you can reference the above Smartwool socks size chart to ensure the right size. If you have specific questions about size and fit, feel free to contact us.
