I switched to trail runners at age 73 and never wore the boots again! Admittedly, the shoes I switched to have anti-pronation and motion control. I also remove the factory insoles and use green Superfeet (which work fine for me, but not for everyone!).

Admittedly, this change was part of a shift to lightweight backpacking. They say one pound on the feet is like five pounds on the back, and I found this to be true. In addition, I have not had a blister since I switched! Nor have I turned an ankle (which used to happen frequently in boots).
