I think it may matter if, like Bulk said, you have neuropathy... Or, and that's something to consider, your blood sugars run high. If you're high all the time it impairs your ability to heal and you'd be infection-prone. But yeah, ask the doc to be on the safe side.
I do have to say though, I used to break my toes on a regular basis and I wasn't allowed to have them taped to a well toe next to it, because "Diabetes!!". I have excellent sugars and no neuropathy, but once diagnosed they kind of tend to blanket things like that. (I taped my own toes repeatedly instead, and I haven't lost a foot yet.)
