Started running last year and, at age 50, getting the right equipment is important for both comfort and for injury prevention.  I tried several sock types and brands from New Balance, Balega, Feetures, Nike, and Under Armor.  Of those, the only ones that I would not recommend are those from Feetures and, especially, Under Armour--they were terrible for me.  The Thorlo's are, by far, the most comfortable and well designed socks I have ever worn.  I have a narrow foot, but these are snug enough to not ever bunch or move around during my runs.  The pads give just enough extra cushioning without making the shoes tight and the material through the instep keeps the socks secure and cool.

They are pricey, but I'd encourage you to try a pair before passing them by on price alone.  You won't be sorry.
