Compression Socks?

Running obsession comes with searching the internet for everything running.  I'm seeing these compression socks everywhere, with some strong testimonials.  So, of course, I have to have them.  Or do I?  The word is that they are great for long runs, keeping calves from being sore and tired, and help with recovery as well.  Some people with shin splints and Achilles tendon issues are swearing by them.

Then there's brands.  And socks vs. sleeves.  Running is quickly becoming a money pit.  A lovely, lovely money pit.

Happy running and God bless!
