Balega Trail Buster. Full stop. I love this sock.
A friend of mine recently asked me if I had any strong preferences for running socks. Like, could I name my favorite brand? No, not so much I said. She confessed that she's in love with Balega socks, a brand that I hadn't even ever heard of. As long as socks don't have any cotton in them, they're pretty much all good as far as I'm concerned.
But... wait... I did tell her that I had a pair I preferred. I found them on clearance at a local running shop a few years ago and I bought two pair. I wore them the next day and promptly went back and bought them out. Nearly five years later, the socks are still fluffy soft and have held their shape. They're like running on pillows. I know it's time to do laundry when I run out of these amazing grey socks. I couldn't tell her who made them because it had never occurred to me to seek them out.
They're Balega, specifically the Trail Buster. They're awesome.
I checked my sock drawer, and there are a few neglected other pairs of non-balega socks (mostly Defeet) stuck way in the back, along with the stretched out sports bras that are really only good for yoga.
