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.

Will Smartwool socks shrink or stretch?

Not with proper care. Smartwool's high-quality wool sock construction methods help your socks retain their shape and fit.

Does Smartwool provide sock repairs?

We don't have a repair service, but if you're not completely satisfied with your socks, you have two years to return them. See the details of the Smartwool satisfaction guarantee to see if we can help you.

What if a pair of socks I order doesn't fit?

We’ve got your back--er, feet! Smartwool offers free returns within 30 days of purchase, so you can easily return any socks that don’t fit. Visit our Free Return Policy for more details.
