While we are discussing SIDI's, I purchased a pair of Geniuses 3 years ago, Size 48. They have always fit fine. My feet have become longer (probably flatter) in recent years, now a new Genius Size 48 seems tight.

I want to upgrade to an Ergo 2. Will a Size 48 Ergo 2 ultimately fit as well as my old Size 48 Genius, even if it seems tight to begin with? (There is no Size 49, so it is 48 or nothing).
