Compression kit!

Id like to know what experience people have had using compression wear, specifically calf socks/wraps??
I have always suffered with niggles on and off in the lower leg (never in the same place), and was considering purchasing a pair of half legs. Ive read some reviews but they seem specific to competition use as opposed to injury prevention.
Can anyone offer any information/advice?

Thanks,
Lynzi

I've used them for the last year or so having always got pain in my lower calves after running and they seem to have helped me.

I had a calf problem leading up to the Florida Half-Ironman in May 2010. I bought some calf socks the day before the race, and they got me through it, and helped my recovery afterwards. It wasn't long before the problem went away, and I could run free again.

Thanks for the responses. I have placed an order and hope to be running again soon.
