I have always thought that pointe work could bring out some of the strength characteristics of male dancing. For women, it is often used in a "femme power" kind of role, kind of a maleness put into a femme body. So to do it with men would be great.
But please, get beyond being self-conscious about what is and is not "manly", especially in training. We cannot define manliness by what it lacks, as a kind of "female dancing minus the girly steps". Avoiding bourrees will NOT make you any more manly. Rather, we must define it by its salient characteristics, what it brings to the table that women cannot.
Once you've done that, it's really no big deal whether or not your guys do bourree in class (I do, it's good for training some things). The color of their shoes is also not a big deal. My legs are pink, so how does wearing peachy-pink shoes make me a girl? Pink ribbons look best on pink ankles. Black shoes are awful, they hide what the feet are doing. I can only imagine using black pointe shoes for some kind of macabre harlequin thing. In general, if you're going to work on your feet in pointe shoes, then you should show them off in white --- or pink. Peachy pink is fine for me, I'm not so fond of the pinky-pink.
