For me, absolutely not. It would be the equivalent of handing them a sharpened sword and putting my neck right under it. Babies/small children don't wear shoes, adults do. When people want to trap you, one of the first things they take from you is shoes.
It makes escape harder.

Also, to me, it is an act of extreme familiarity. Familiarity of that sort is not something I think is a good idea to have around a therapist.

And I like wearing shoes. They make me feel safe and strong.

I certainly understand some of these things are cultural as well as simple personal choice. I would not ever take my shoes off at any professional appointment or at work. No one, that I saw, condemned those who choose to do so.
