I’m so serious about playing keyboards that I would wear those silly looking shoes if they would make play better!

I always wear piano keyboard socks when I'm playing!

I stick to t-shirt that indicate i am not that serious about playing keyboards, as it needs to be fun.
I am serious however about improving my skills..

Shoes and playing better only apples to organ players and not keyboard players. (Bass pedals)

But, if it makes them feel better, then do whatever.
