I want to start a bit of my history, I was in the military and I used to run all the time because I had to. I left the military and stopped running about 3 years ago, I've always had a hard time finding a good fit with enough support. Back then my weight bounced between 200-210 Lbs I had runners knee, shin splints and tended to rolled my ankles, I used to run a 5K in just under 22 minutes. In addition to having a heavy weight I have flat feet. I want to get back into running and I am slowly progressing, one thing that discouraged me was (and I emphasize was) my knee pain . Currently I am 235 Lbs and these shoes have restored my optimism in running. I do not use runners tape or knee braces. I will more than likely purchase 3-5 more pairs and hide them away in my closet just in case.
