For high school, we had to have all white shoes for summer parade (white shorts, the years orange band T shirt, and specific calf high socks that we bought from the school.
Fall uniform was black shoes of our own, must be all black with high black socks.
Often the spray paint was pulled out to ensure "all one color" much to the annoyance of parents on a budget trying to balance kids' fashion desires with a need for marching band shoes. [waves]
I became proficient in using tape well enough and picking the most bland shoes I could. So my shoe game was terribly dull until college. When I promptly got the loudest most colorful running shoes I could.
My senior year though we had new uniforms with white pants and white shoes that were uniform marching shoes, so that at least alleviated the shoe budget for some families
