It's always interesting to hear from others on what they like and use. Like you, I have socks I only use for running and have tried Darn Tough, Feetures, Smart Wool, Voormi, and Injinji. I don't like the feeling of anything between my toes (I don't even like flip flops for that reason) so the Injinji socks aren't my favorite but if I know my feet will be constantly wet on a run I still wear them as, like you, I've never had a blister in those socks. For that reason alone I'll always own a pair of Injinji socks for running in wet conditions. Darn Tough are probably my favorite but all of the brands I mentioned work well. The Voormi socks run large and got holes in the toes after only 75 miles or so, which was disappointing, but I darned them and they have been good ever since. The Injinji and Feetures also developed toe holes but not for a couple hundred miles. The Darn Toughs are just more durable all the way around, at least for me, and I can get 1,000 miles plus out of a pair. Maybe that's why they are my favorite, after spending so much I want them to last and they have the bonus that when I wear them out I can send them in for a free warranty replacement. I haven't tried the Feetures warranty yet but likely will at some point. Those socks feel great but slide around in my shoes a bit more than the others. I'm not sure good socks helped me at all with reducing joint pain but they do help prevent blisters and allow my feet to keep going on longer runs.I'll also echo the comment about good socks. It seems crazy to spend 20 dollars on a single pair of socks, but if you only use them for running/working out, they will last a long time. I've tried and been happy with Darn Tough, Smart wool and Balega. My personal favorite though is the Injinji (yes the toe socks). Even with completely soaked socks, I've never had a blister with them.
