Lose the boots and put everyone in comfortable shoes. The color of the shoes and socks would match the trousers (no more onesies please). The exception to the shoes would be the security personnel duty foot wear would be similar to hiking boots (no laces?), dress uniform for security would be shoes.
As I said, no single piece uniforms. In TMP one of Kirk's uniforms was a white short sleeve shirt (with small epaulets), and grey trousers, this will be the basic everyday duty uniforms
look, but with different colors by sections.
Senior command (and staff). White shirt, black trousers.
Other command (bridge, etc.). Sand and black.
Engineering and support. Red and black.
Medical. Pastel green, teal.
Science. Medium blue, navy.
Security. Khaki and brown.
