Two questions. (I know nothing about Sidi shoes other than that they are a poor fit form my feet, as are most shoes.) Did Sidi manufacture go to Asia since your previous pair? Have your feet splayed out as is common as we age. Mine have. I can still wear my old, well used shoes but I cannot imagine trying to put on NOS versions of those shoes. Most of my shoes are now a full European size larger than what I used to wear.

I ask that first question because I had a pair of Italian made Vasque hiking boots that were comfortable the moment I put them on. Like really, really comfortable. Bought them '89 and hiked hard for three days that weekend. Loved them. They disappeared when my marriage ended. Went to REI to try on the exact same shoe. Didn't matter the size; I could not make them work. Employee told me manufacture had gone to Asia and that the lasts had changed. Things do change. I now have a pair of Vasques I bought last year, different model, that aren't as good as the first pair but not far off.
