These might not be the most attractive shoes, but they are incredibly comfortable.  After having surgery I was gearing up to start running again and needed a great pair of supportive yet comfortable shoes.  These were just the ticket, I've always experienced shin splints when running and that doesn't happen with these.  The pair I had lasted about a year and now that I need a new pair of running shoes, I'm of course looking solely at a new pair of zigs.
