No, I don't like them and I don't think they're appropriate for a GP ( or any HCP really)
Wear them in your own time if you want .
But if I go to my GP , its about me . I don't want to think " My , you're whacky/umconventional/human"
I'd be "What the feck were you thinking ?"
Uniform at work is there for a reason.
A dress, a tunic and trousers, a suit . It inspires confidence.
I would not want to be given serious possibly life changing news by someone wearing those .
My work shoes are flat black lace-up, inoffensive and professional.
(There was a hair thread on MN a while ago, same thing . Do I want a GP with blue hair ? No .
Would I think "Oh you're human quirky and a bit oddball, I've warmed to you"? Again, No.
