Buying guide
Merino wool or synthetic running socks?
Merino wool controls odour well and feels comfortable across a wide temperature range. Synthetic socks tend to dry faster and often cost less. Many of the best socks blend both.
What height of running sock should I choose?
No-show and low socks suit road running in warm weather. Crew and mid-height socks add protection against debris on trails and warmth in cold weather.
How can I stop blisters when running?
Choose a snug sock that does not bunch or slide, avoid cotton-heavy fabrics that hold sweat, and consider toe-sock designs if you get blisters between toes. Break in new socks and shoes before a long run.
How often should I replace running socks?
Replace them when the cushioning flattens, the fabric thins or holes appear. Frequent runners often go through a pair every few months.
