I think this could be true for certain feet. But ours (myself and older children) have been using regular running shoes for all of our rmnp hikes including longs for the past two trips. The first trip I used keen mids and my feet got sore. The next year was trail runners and that was better. This past year was normal road running shoes and my feet felt the best. But that could be just because the feet have toughened up over the years, who knows.....
Bottom line is that happy feet tend to make a happy hiker. Use what works.
They (can't remember who exactly now / but people I would trust) have talked much about how wearing more flexible shoes or boots and lower top shoes and boots can very much improve your climbing on steeper rocks and trail because of making you more comfortable due to that flexibility. Makes sense to me.
Changing for different types of hiking or packing may be the the way to go for some. I like my boots but so far this year I have been using low top casual "tenni type" shoes on the easier, short hikes and they work fine. The sole is a little thicker and "treaded".
Whatever works best for everyone. Switching out types is just another option.
Good Hiking To You All!!!
