miracle clothing

Today I went looking for some un-floppy nylon running shorts online, and here is what I learned about spandex shorts:

Why Compression? Spandex shorts increase blood circulation which oxidizes the muscles during exercise. More oxygen will reduce the build up of lactic acid which can be painful. Compression from our bike shorts also supports muscles to reduce movement. The excessive movement of flesh during exercise can be tiring. These compression shorts can also help reduce delayed onset soreness from exercise by compressing muscles to increase the blood flow to heal muscles after workouts.

I'm not sure I can afford such awesomeness all in one pair of shorts.
