Best Running Socks (2025): Compression, Merino Wool, Toe Socks

Running badly socks suck. If running over 65 marathons and 20 ultras and traveling most of Europe has taught me anything, it’s this: a runner is only as happy as his or her feet. You can spend hundreds of dollars on the best running shoes, but if you put your foot in an old athletic sock, you’re still likely to end up with blisters.
Running socks, along with running underwear, are probably as essential to your comfort as any other item of clothing you train in. This is why regular ultra runners change socks for a big psychological boost mid-race. If your socks don’t fit well, trap sweat, or fail to cushion your steps, it’s a quick ticket to hot spots and Blisterville. And if they don’t look the part, forget PR.
To help you avoid all that, we’ve scoured the endless variety of cuts, cushions, and, yes, colors, to find options that are worth the money. Whether you’re someone who logs miles daily for fitness, an ultrarunner who tames the trails, or a twice-weekly jogger, there’s a sock for you. Don’t see anything you like?
