I picked up 2 pair of ProDry extreme roll tops today to see how the hold up. And make sure they do not slip down my heel. Also a pair of just pro dry low to check those out. i am culling all my other socks as I wear a pair and if they slip down - trash at end of the round.
I am doing the same thing for the most part. My sock drawer is pretty full at the moment, but most don't stay up well or are starting to wear out in areas that cushion is a must. Replacing with ProDry Extreme lows and Roll Tops as needed.
