Sorry to hear that Jean Cavallaro is no longer making flute case covers. I have several and never had a problem with any of them. Intelligently designed and very well made. Nothing else on the market I’m aware of as nice.
UPDATE 11/16
I was able to locate a Cavallaro cover for a student flute case with B foot at Weiner Music:

There are also some Cavallaro covers still available at Carolyn Nussbaum
