Obviously from your thread title this is inspired by the high school band whose guard members' bare feet were so badly burned on the turf yesterday in a Bands of America prelims competition in Texas that a doctor told them they couldn't perform in the finals that evening (for which they had qualified).
As it happens, over in DCA, the Caballeros' guard was barefoot for daytime prelims at championships in 2014 in New York and some membes feet were burned, but apparently not as badly.
Curious why you asked for this topic, which seems like a legitimate one for discussion here, to be deleted.
