Compression socks are awesome. When I ride an hour and a half in the morning, stand on my feet for 9 hours, then ride an hour and a half back, my feet feel a ton better at the end of the day. Like many things, I thought it was hooey at first, then tried it, and thought "well no ####, there's something to this."
A couple months ago when I got my powermeter my normalized power was about 170 with an average HR of 160. Yeah, that's pretty out of shape.
My commute home got cut in about half last night due to date night with the wife, but my normalized power over 12 miles was 381 with an average HR of 149. I'm still not fast, but I'm practically giddy.
