Frequently Asked Questions
Are merino socks better than cotton for work boots?
Absolutely. Cotton holds moisture, causing blisters, odor, and cold feet. Merino wicks moisture, regulates temperature, and resists odor even after multiple wears. The upgrade is transformative.
How do I prevent steel toe rub?
Use socks with cushioned toe boxes (like the Darn Tough Steely line). Also ensure proper boot fit—too tight causes rubbing, too loose causes movement that causes rubbing.
How many work socks should I own?
Minimum 5 pairs (one per workday). Ideally 7-10 pairs to allow rotation and reduce wear on individual pairs. With daily washing, this also ensures you always have clean socks ready.
Should work socks have compression?
Light compression (arch support) is beneficial for long shifts. Heavy compression socks are a different category—good for specific circulatory needs but not necessary for most workers.
