This is the main reason I've heard. That is, if the soles are stiff, they will not bend as much, which will create more wear on the toe portion of the sole. I've worn some AEs for the first time without much carpet wear, and definitely noticed some wear at the toes. So, I had taps put on, but now that they're broken in, it doesn't seem like the taps are getting much wear. This suggests that if I had just broken them in on carpet (or at least with minimal pavement exposure initially), taps would not have been necessary.
