Byebye aching knees

I certainly hope this solves the problem of my slightly swollen knees. I've been ignoring them, mainly because I still doggedly want to run 6km every day. So I've done this, ditch the nike free run ( which gives no support) and opted for a stiffer base which hopefully will absorb the impact and take some pain off the knees. Did 6km on the treadmill with these...no ache. But now I'm down with a cold in the head. Most annoying. So I didn't jog today and I feel like a miserable ole bat!
