It might sound silly, but different terrains tend to be „interesting“. I also feel it has an impact on how i walk and how i stand - so actually back problems and (minor) aches are either easier or gone.

I, too, travel the alps, nock mountains, katschberg mountain, Dachstein etc. I totally wear bulky hiking shoes in the mountains, though, as you definitely want the protection for your foot and ankles. However, i more often than not even hike easy trails in those barefoot shoes. I guess i just am used to it so much that those protective shoes feel too heavy and bulky, even if the bedding is comfortable.

But fir the day to day footwear you have to wear necessarily I almost always choose barefoot shoes over the few remaining normal ones. I will keep one set business shoes, one pair of winter boots and my mountain equipment, everything else will be gone quite soon.
