My mother refuses to wear shoes. How in the world can I get shoes on her?

My mother has vascular dementia with behavioral disturbances. (dr said she thinks it’s probably mixed dementia but was just listing as vascular for now) She has delusions. Her legs and feet were swelling due to cardiac problems and her shoes wouldn’t fit for a while but now with compression stockings, the swelling has gone down enough that she can wear a few of the pairs she has. We have repeatedly tried them on her, she says they fit then a couple days later is back to having “no shoes to wear”. Currently the only thing she will wear are the gripper slipper socks they give you in hospitals. ( although she told the neurologist Monday she (the dr) is so dumb the Dr didn’t KNOW they were shoes. Yep that was a rip roaring visit , hence the behavior disturbances diagnosis lol!)

The AL wants her wearing shoes for safety plus obviously she needs shoes when she goes out. We just tried buying her a new pair but same thing, they fit , she says they fit but an hour, day or week later refuses to wear them and says they don’t fit. We try them back on and the cycle repeats. I don’t think even pretending they are a new pair would help since we have bought her new pairs with the same results.

I know with delusional thinking you can’t argue but how in the world can I get shoes on her lol?
