Query: Seems to work for my Runner's Knee

I was having pain in my knee and turns out I had Runner's Knee. I bought these to help relieve the pain and I've been using them for a little over a month and my knee pain has definitely improved. I still have a little after I run, but these things have helped. I'm also doing Terminal Extension exercies to help strenghten the muscles around my knees. To help them last longer, I keep them in my running sneakers and only where them to run.Also, my Reebok sneakers are a size 7 and I got the 6-6.5 size and they fit in my sneakers perfectly. However, they don't fit in my size 7 New Balances.
