Isn’t pine too soft for flooring?

I’m glad you asked. I’ve personally walked on white pine floors (in New England) that are over 300 years old. Now granted, they are not looking their best, but neither would I after 3 centuries of being walked on! Sure, pine will dent quicker and deeper than oak, but in most cases it just adds to its patina and history and in no way shortens its life span. After all, if owning a floor that never mars and looks the same as the day it was installed is your goal, real wood isn’t a good choice anyway.
