Frequently Asked Questions
Is merino wool good for sweaty feet?
Yes, excellent. Merino wicks moisture away from skin, can absorb 30% of its weight while feeling dry, and has natural antimicrobial properties that prevent odor. It outperforms synthetic for sweaty feet.
Should I avoid thick socks if I have sweaty feet?
Generally yes. Lighter socks allow more airflow. However, quality matters more than thickness—a light merino sock beats a thick cotton sock every time.
Do moisture-wicking socks actually work?
Quality merino socks absolutely work. The key is the fiber's natural properties, not marketing claims. Merino wool's structure actively moves moisture away from skin.
How do I reduce foot odor?
Merino wool socks are the biggest factor. Also: rotate shoes (let them dry 24 hours between wears), wash feet thoroughly, and replace insoles periodically. Merino can be worn multiple times without odor.
