I'm gonna argue from the other side of the fence.  I am a woman who wears men's shoes most of the time, or unisex shoes, like Dr. Martens.  I wear blokey shoes because I find them more comfortable, durable, and practical.  You can easily get wide widths if you need, they are made more true to the shape of a foot, the materials are stronger.  
If some guy wants to abandon the comfort and practicality of men's shoes for the pinchiness, instability, and fragility of women's footwear, then that's his prerogative.  I can't fathom it, but I won't condemn it, either.
