I have a knee replacement done few years ago. My doctor toll me that I could play doubles. I did and was having problems with my food on the good knee and it was kind of hard with my injured knee. Then, I purchased these sneakers. It is wonderful. No problems with toe nails. The food on the good knee doesn't hurt any more and I get full support on the food with my knee replaced. I find myself forgetting that I have an injured knee and do not have to ice my feets after games. I strongly recomend these sneakers. In fact, I am about to buy my second pair.
Great for playing tennis in or shoveling show with. These are the best ever
