I had that same issue when i was in school and i just bought a pair of white nikes that worked fine. When those wore out i just bought whatever color shoes i wanted and just told my profs. that it was impossible to find mens white nursing shoes and they all understood for the most part or just didnt care.
Im one semester away from graduating from a pretty good BSN program and am starting to look for jobs. If i want to eventually become a CRNA, which ICU area would be best. Im most likely going to be at a major hospital so its really just a matter of which area rather than hospital size or amount of patient flow. Thanks
