Much of nature was inaccessible to them simply due to the fact that it was too cumbersome, slow, and dangerous to walk there.
The only people wondering why we switched to boots as soon as possible are from the city, simply because they incapable of wear boots for a few hundred miles without feeling pain, lol.
