Hi, I am not a runner. I am looking for some good walking shoes. I am currently using sketchers go walk ones. It's more like casual shoe. I am having knee pain because of walking in a wrong way or wrong shoes. I did walk in the hilly roads without proper shoes. So, planning to change to a good walking shoes. My PT also recommended to try shoe inserts. Anyone used shoe inserts before? I have to get a median arch support. Anyone tried that? Thanks.
