The best socks for marathon runners

When it comes to marathon running, your socks matter more than you think. The wrong pair can lead to blisters, overheating, and discomfort—none of which you want to deal with at mile 20!

A great pair of running socks should offer breathability, durability, moisture control, and anti-blister protection. Whether you’re running your first 26.2 miles or training for an ultramarathon, choosing the right socks can make all the difference.

As a long-time ambassador for Runderwear, I can confidently say their anti-blister socks have gotten me through multiple ultras, sub-3 marathons, and everything in between. They are my go-to for race day and hard training sessions.

This guide will walk you through the best running socks for marathons, including my personal favourites and the best on the market today.

What to Look for in Marathon Running Socks

Before diving into specific brands, here’s what you should look for in a high-performance running sock:

✅ Blister Protection

Blisters can ruin your race. The best socks use seamless construction, targeted padding, and moisture-wicking fabrics to prevent hot spots and friction.

✅ Moisture-Wicking Materials

Keeping your feet dry is key. Look for merino wool, synthetic blends, or Drynamix fibres that draw sweat away from the skin.

✅ Arch Support & Cushioning

Compression-style socks or cushioned options help reduce foot fatigue and improve circulation, essential for endurance runners.

✅ Temperature Regulation

Some socks adapt to temperature changes, keeping your feet warm in winter and cool in summer—crucial for long-distance races.
