Darn Tough Socks Size Guide

Find your best fit based on your shoe size. Darn Tough sock sizing is designed around standard shoe size ranges for a comfortable, secure fit.

How to Measure

• Measurement Area: Foot length (heel to longest toe)
• Units: cm / inch
• Method: Place your foot flat on a piece of paper while standing. Mark the back of your heel and the tip of your longest toe, then measure the distance between the two points. Compare your measurement with your usual shoe size range.

If you are between sizes, choose the smaller size for a closer performance fit or the larger size for a roomier feel.

Note: A specific foot-length conversion chart in cm/inch was not provided in the available product information. The size guide above uses official shoe-size ranges only.
