I work in a machine shop where I stand on concrete the whole shift. I'm at a point in my life where I've had more good days than I have ahead of me. So I need every edge I can get when it comes to keeping my feet from hurting all day long. These shoes are the most comfortable and supportive I have ever had for my aging flat feet. I plan to buy another pair in the near future to replace a new pair of spare shoes about every 3 or 4 months (I can wear 3 to 4 pairs a year). - I don't recommend them. enough.
