Dream on Ben Nevis

I was making a jogging ascent of Ben Nevis (unlikely, even in my prime).
The problem was that I was wearing a pair of brown leather town shoes.
I remember these shoes as I wore them in the sixties.
They were not designed for the Ben.
As I ascended, rather slowly, I had to download a black and white dream into my brain.
This kept me busy and I tended to forget my feet.
Makes perfect sense.
