Hi, @duchwalking pilgrim.
The Cleveland Clinic‘s website is one of my go-to places for questions like these, because of the unbelievably great treatment they provided a relative years ago.
The years can literally reshape your feet

Bottom line is, yes feet change over the years. I think a lot of us have found that our feet have widened, usually not dramatically from one year to the next. But there is a tipping point, when you just have to change your footwear. I had always used Solomoon hiking shoes, but my toe box was widening, and I made the happy transition to Altras a few years ago. Anyway, you should not be surprised to learn that you need a longer and/or wider shoe.
So much info on the forum about shoes, overwhelming in fact, but I hope you can get yourself to a good store and get some professional advice in addition to all that you will find here! Buen camino, Laurie
