I know your frustration. The day before I started to move into my new sewing studio/room I knew my pinking shears were on my table. Once out there I couldn't find them,had looked everywhere. I knew they had to be there. I have a very large quilted bag with lots of pockets. I had batting and fleece offcuts in said bag. I felt in all the pockets searched among offcuts - nothing!! Six months later I decided to take this bag to a retreat so removed all my offcuts to a basket:- surprise, surprise there were my shears. I swear I'd went through that bag at least 3 times but had still missed them.
I agree shears are a lot larger than a foot but don't give up. Hope you find your foot soon.
