Frequently Asked Questions
How many hiking socks do I need?
3-5 pairs for regular hikers. This allows rotation (extending lifespan), having a backup on multi-day trips, and always having clean socks available. For thru-hiking, 2-3 pairs is standard.
Should I wear liner socks with hiking socks?
Generally no. Quality hiking socks like Darn Tough are designed to be worn alone. Liner socks were needed with older wool socks but modern merino blends wick moisture effectively without them.
Light or full cushion for hiking?
Mid-cushion (like the 1466) is most versatile. Full cushion for cold/rough terrain and well-fitted boots. Light cushion for hot weather, trail running, or snug-fitting shoes.
How do I prevent blisters when hiking?
Proper sock choice is key: merino wool, correct fit (snug but not tight), and no cotton. Also ensure boot fit is correct, break in new boots gradually, and keep feet dry.
Can I machine wash hiking socks?
Yes, but use cold or warm water and avoid high heat drying. Darn Tough specifically says machine wash warm, tumble dry low. This extends lifespan versus high heat which degrades merino fibers.
