I had some knee troubles that had really started to slowly become worse after moving out of the area. Once coming back I was barely running at all and not without great pain. Spent lots of money at doctors and rehab places and would get some relief from drugs or stretches but still had pain and swelling. Met with Dennis and brought in my last several pairs of shoes and he was able to recomend a couple shoes to try and made some small modifications to the pair I did buy and haven't missed a step since. I have gone back a couple of times and would recomend to anyone, with or without knee or foot problems. You don't get this type of knowledge and service most places you buy shoes.
