I've used Drymax for years. The price hurts, no doubt. But because I have years of stats, I know that cotton socks don't last at all, plus they are terrible for sports. Even if you don't do sports and worry about blisters, Drymax socks outlast cotton so disproportionately that you will not be wasting a penny. Spend and equal amount on cotton socks, all of them will be worn out in the same amount of time as your Drymax.
I wish I could say they last longer and are a better value, but in my opinion they are the same value in longevity for anyone.
If you're an athlete who cares about performance, too, then Drymax becomes the better value, for sure.
